Seriatopora histrix

Seriatopora histrix "Pink Bird's Nest Frag" - Small

Bird's Nest Corals ( Seriatopora sp. ) grow in a colony with thin branches that grow in random directions to resemble the tangle of twigs of a bird's nest. They grow best under bright lighting and moderate to high flow. This is one of the most popular corals among coral propogators and many varieties of frags are available.

Pectinia sp. "Spiny Cup Coral" - Small

The Spiny Cup Corals ( Pectinia sp. ) are unique-looking corals, usually ranging from dark to light green. Less commonly, blue, red, purple or yellow colonies can also be found. It can form a cup-like shape with sharp points protruding from the center of the coral, branching colonies, or may resemble some deep-walled maze brain corals or leafy leather corals. Pectinia is not a very hardy coral and will do best in a well-established aquarium with good lighting and regular addition of trace elements. Pectinia will use photosynthesis to feed but can benefit from supplemental zooplankton feedings. Water movement should be moderate to high to help carry waste and debris away from the colony.

Sinularia flexibis

Sinularia flexibis "Spaghetti Leather Coral" - Medium

The Spaghetti Leather Coral ( Sinularia flexibis ) is usually white or tan in color and can have colored polyps. It has long spaghetti-like extensions that grow from a central trunk. Large colonies have been compared to Weeping Willow Trees. Bright yellow or green colonies can occasionally be found and require highly lighting than the more common tan or white variations. Spaghetti Leather corals are usually good for beginners in that they are hardy and easy to keep. They grow best under medium to high light conditions with adequate water movement. Spaghetti Leather corals rely mainly on photosynthesis as a food source, but can benefit from additional zooplankton supplements. These corals can grow fairly large and should not be kept in a crowded aquarium. They can be propagated easily for regular maintaining "trimming" as well as to make new colonies. Sinularia corals are some of the more aggressive soft corals. They can grow quickly and may overcome some less aggressive colonies, and they can release chemicals into the water as a means of "chemical warfare" among corals in their competition for space. Sinularia corals are also especially productive with the mucus coating they secrete. They should only be kept in systems with moderate to high water flow, efficient skimming, and high water turnover to help the coral shed its mucus coatings and to remove it from the tank before it can irritate any other corals. This is a Restricted item and is not covered by our Arrive Alive 5 Day Guarantee.

Cladiella sp. "Colt Coral" - Small

Colt Corals ( Cladiella sp. ) are one of the easiest corals for beginners. Colors can vary from browns to pinks or yellows. Bushy polyps extend from tree-like trunks and are usually darker than the base color of the colony. The colony itself is slippery in texture compared to many other rougher corals with a similar appearance. Colt Corals adapt well to most conditions, although they will have brighter colors under more intense lighting. They receive some of their nutrition from the photosynthetic algae in their tissues but will also filter-feed and absorb some nutrients and minerals from the water. The corals should be supplements with planktonic filter-feeder foods, especially under less intense lighting. Colt Corals are one of the more aggressive leather corals. They should not be placed close to sensitive corals as they will "attack" and show aggression towards other corals by releasing slightly toxic chemicals into the surrounding water. They shed a mucus layer periodically that can irritate other corals and they can also grow fairly quickly, outcompeting and overgrowing neighboring colonies. These corals are easy to propagate and "frag" in home aquariums. A piece of the colony can be cut off with a sharp blade or shears and allowed to re-attach to a hard base like a frag plug, piece of rubble rock or shell. Reduce the flow around the new frag until it attaches or use a piece of netting or fishing line to help the new piece stay in place.

Echinophyllia sp.

Echinophyllia sp. "Green and White Chalice Coral"

Echinophyllia is a colorful coral that is easy to maintain in a home aquarium. It is a hardy species that that will grow in almost any type of light environment but will grow best and have the brightest colors under moderate to high lighting. Caution should be taken when placing Echinophyllia near other corals as it has long sweeper tentacles that may sting them. Echinophyllia can easily be fed meaty foods such as mysis or krill, but will only feed at night.

Acropora sp. "Assorted Acro Frag" - Small/Medium

Acropora is one of the most popular and easily recognisable corals in the aquarium trade. It is easy to propogate and, if given the proper conditions, not difficult to maintain. Lighting must be high and supplemental planktonic foods can be given occassionally. Trace minerals and calcium levels should also be kept high for proper skeletal formation. Flow should be indirect but moderately strong to help bring food to and carry waste away from the colony. With more than 350 documented species of acropora around the world, colors and formations are practically limitless. The same species can look vastly different depending on where it is growing on the reef. Colors can vary from browns to blue, green, or pinks. Most commonly kept in the aquarium trade are the neon green, blue and purple varieties.

Galaxea sp. "Green Galaxy Coral" - Small

Galaxy Corals ( Galaxea sp. ) are very popular with many aquarists because of their hardiness and beauty. Most will consist of large colonies of separate corallites with small tentacles extending from each one. Be careful when placing this coral near other corals as it has "sweeper tentacles" that can stretch up to 5 inches from the colony and will sting other corals that may compete for space. A moderate flow of water over the coral allows for sufficient feeding. Invertebrate foods such as Marine Snow or Microvert along with other types should be fed once or twice a week and care must be taken to make sure water quality is always good. If the tank contains extremely strong lighting, this coral may be placed on the substrate of the tank but generally mid to upper levels of the tank are a more appropriate choice.

Acropora sp. "Colored Acropora Coral" - Medium

Acropora is one of the most popular and easily recognisable corals in the aquarium trade. It is easy to propogate and, if given the proper conditions, not difficult to maintain. Lighting must be high and supplemental planktonic foods can be given occassionally. Trace minerals and calcium levels should also be kept high for proper skeletal formation. Flow should be indirect but moderately strong to help bring food to and carry waste away from the colony. With more than 350 documented species of acropora around the world, colors and formations are practically limitless. The same species can look vastly different depending on where it is growing on the reef. Colors can vary from browns to blue, green, or pinks. Most commonly kept in the aquarium trade are the neon green, blue and purple varieties.

Sarcophyton sp.

Sarcophyton sp. "Toadstool Leather Coral" - Medium

Toadstool Leather Corals ( Sarcophyton sp. ) are hardy, undemanding corals. With the exception of the Yellow Toadstool Leather ( Sarcophyton elegans ), most can adapt well to a wide range of conditions. These corals have a short "trunk" supporting a mushroom-shaped cap that can grow very large in diameter. Polyps extend periodically from this cap. Color is usually tan but can range from beige or darker brown to green or yellow. These corals may benefit from occasional feedings in the aquarium but survive mostly on photosynthesis from the zooxanthallae algae living in their tissues. They should be kept in a tank with moderate to high lighting. Toadstool Leathers can survive in lower lighting but will often change color and rely more on planktonic feedings if not given enough light. Conversely, they may become stressed in extremely high light and should be acclimated to any new lighting conditions carefully. Water movement should also be moderately strong to assist in waste removal and in the coral's periodic shedding of a mucus layer. These corals have low to moderate aggression and can easily fall victim to other aggressive corals although the mucus layer produced by their shedding can irritate some corals and they can grow large and outcompete other coral colonies. They also benefit from trace element supplements, particularly iodine which can assist in growth and in shedding. Most Toadstool Leathers can be successfully and easily propagated by either cutting the "cap" of the coral with a sharp blade and mounting the new piece onto a base or by cinching off a new piece by gradually tightening a length of fishing line, rubber band or zip tie around the area to be cut.

Acanthophyllia deshayesiana

Acanthophyllia deshayesiana "Green Meat Coral" - Medium

Meat Coral is one of many common names used in describing Acanthophyllia deshayesiana , but this is an apt title, as this species has a thick and fleshy polyp. Their fleshy skin is rather delicate and care must be taken when placing them in the aquarium so the thick, toothy skeleton doesn't cause too much damage to the soft tissue. When the soft tissue expands, it drapes dramatically over the edges of the skeleton. Color may vary from red-brown to bright green or red, and, in some cases, specimens may be striped or mottled with another color. Place these corals either low in the tank or firmly anchored midway up in the tank, with low water movement. They do produce food through photosynthesis, but will also except an occasional meaty foods placed near the oral opening. Meat Coral is similar to, and often confused with, Scolymia corals. (Note: This species was formerly identified as Cynarina deshayesiana but has recently been reclassified by the U.S. Fish & Wildlife Service.)

Echinophora sp.

Echinophora sp. "Blue Hedgehog Coral Frag" (Jason Fox)

The Blue Echinopora Frag is a small piece of the rare blue Echinopora variety popular with reef aquarists. It has been propogated in captivity and is mounted on a small artificial base. Echinopora is known in the trade as Hedgehog Coral or Chalice Coral. Very high, intense lighting is needed to keep the colony healthy and to keep its color vibrant. Insufficient lighting can cause the color to change to a dull tan or greenish color. Supplements of very small food items like phytoplankton, pastes, or rotifers can be added as well. Moderate flow is also required. The artificial base that the frag is mounted on can be affixed to live rock or other surfaces to keep the small piece in place. Jason Fox is well known within the coral enthusiast world as one of the premier coral farmers in the U.S.A. Jason has spent years accumulating a spectacular collection of corals in his farm, TFP is proud to offer some of Jason's signature corals as part of our coral frag collection.

Plerogyra sp. "Bubble Coral" - Large

Bubble Corals ( Plerogyra sp. ) get their name from the daytime expansion of their tissue. Also called Cat's Eye or Grape Coral, these corals can have a variety of blue and pearl colorations as well as more rare green varieties. These corals are considered aggressive because they use sweeper tentacles that can expand several inches at night for feeding. They will also use these sweeper tentacles to sting adjacent corals if they are a threat to their territory. For this reason they will need sufficient room to be able to expand. These corals require medium to high light, and require low water movement for full expansion. In most tanks they should be placed midway and higher in the tank to thrive. As Bubble Corals can expand and can easily be damaged by their sharp skeletons, Bubble Corals should be firmly secured into place to prevent them from falling over.

Dendronephthya sp.

Dendronephthya sp. "Carnation Coral" - Large

Carnation Corals ( Dendronephthya sp. ) are unique soft corals perfect for adding some color to a reef aquarium. They are most often found with light trunks and polyps in shades of red, orange, or pink in the aquarium trade, but other colors can be found on rare occasions. The colony can expand or deflate greatly with conditions. These corals are found in low light and even dark environments, like caves and under rock ledges. In the home aquarium, they can be kept under low or moderate light, and do best when hung upside down from the rockwork. They feed both by filtering particulate foods from the water column, as well as by absorbing nutrients directly from the water. They need a constant supply of food and will slowly starve if not provided with enough. These corals typically reproduce by "budding", in which a new colony or stalk will split from the parent colony under the right conditions. This is a Restricted item and is not covered by our Arrive Alive 5 Day Guarantee.

Cycloseris sp. "Orange Plate Coral"

Cycloseris plate corals are very closely related to Fungia sp. plate corals with some small skeletal differences. Its skeleton forms a cupped disc with ridges that radiate from a central oral opening. Cycloseris plate corals tend to have a more mound-like shape than the more common Fungia corals. These corals come in a variety of colors, usually green, pink, or purple. Short tentacles extend upward on the upper side of the animal. These corals have a medium aggressiveness rating because they are quite mobile on an open surface, and can sting other corals that it may come into contact. Place this specimen on a gravel or rubble bottom in direct light, with a medium to low water movement.

Distichopora sp.

Distichopora sp. "Purple Fire Coral"

Several species of coral are regularly known as "Fire Corals". Distichopora sp. grows in blunt-tipped face-shaped colonies. Stylaster sp. has pointed tips on its branching colonies. Millepora sp. has a variety of forms and is the most notorious for delivering a powerful sting if touched. Stylaster and Distichopora are both filter-feeders and are not photosynthetic. They should be spot fed regularly and placed in moderate to high water flow, preferably in a low-light or overhang placement. They have a hard calcium carbonate exoskeleton and race mineral and calcium levels in the aquarium should be monitored for proper growth of the coral. Millepora is photosynthetic and needs moderate to high lighting and flow. Stylaster and Distichopora are both nonaggressive and very sensitive, delicate corals. Millepora is much hardier but is also much more aggressive.

Acropora sp. "Yellow-tipped Acropora Coral" - Medium

Acropora is one of the most popular and easily recognisable corals in the aquarium trade. It is easy to propogate and, if given the proper conditions, not difficult to maintain. Lighting must be high and supplemental planktonic foods can be given occassionally. Trace minerals and calcium levels should also be kept high for proper skeletal formation. Flow should be indirect but moderately strong to help bring food to and carry waste away from the colony. With more than 350 documented species of acropora around the world, colors and formations are practically limitless. The same species can look vastly different depending on where it is growing on the reef. Colors can vary from browns to blue, green, or pinks. Most commonly kept in the aquarium trade are the neon green, blue and purple varieties.

Sinularia flexibis

Sinularia flexibis "Green Spaghetti Leather Coral"

The Spaghetti Leather Coral ( Sinularia flexibis ) is usually white or tan in color and can have colored polyps. It has long spaghetti-like extensions that grow from a central trunk. Large colonies have been compared to Weeping Willow Trees. Bright yellow or green colonies can occasionally be found and require highly lighting than the more common tan or white variations. Spaghetti Leather corals are usually good for beginners in that they are hardy and easy to keep. They grow best under medium to high light conditions with adequate water movement. Spaghetti Leather corals rely mainly on photosynthesis as a food source, but can benefit from additional zooplankton supplements. These corals can grow fairly large and should not be kept in a crowded aquarium. They can be propagated easily for regular maintaining "trimming" as well as to make new colonies. Sinularia corals are some of the more aggressive soft corals. They can grow quickly and may overcome some less aggressive colonies, and they can release chemicals into the water as a means of "chemical warfare" among corals in their competition for space. Sinularia corals are also especially productive with the mucus coating they secrete. They should only be kept in systems with moderate to high water flow, efficient skimming, and high water turnover to help the coral shed its mucus coatings and to remove it from the tank before it can irritate any other corals. This is a Restricted item and is not covered by our Arrive Alive 5 Day Guarantee.

Heliofungia actiniformis

Heliofungia actiniformis "Long Tentacled Plate Coral" - Large

Long Tentacled Plate Corals are a bottom dwelling stony coral, however they are often mistaken for sea anemones. This is because when their tentacles are fully open they completely obscure their skeletons, giving the illusion of a soft bodied anemone. Much the same as short-tentacled Fungia sp. disc corals, Heliofungia 's skeleton forms a cupped disc with ridges that radiate from a central oral opening. These corals come in a variety of colors, usually green, pink, or purple. Tentacles extend several inches upward on the upper side of the animal, and may have brightly colored tips. These corals have a medium aggressiveness rating because they are quite mobile on an open surface, and can sting other corals that it may come into contact. Place this specimen on a gravel or rubble bottom in direct light with a medium to low water movement. They will produce their own food through photosynthesis but will also accept frozen food such as mysis shrimp or brine shrimp. They are quite interesting to watch and will actually pass the food up the tentacles to the mouth of the coral.

Parambassis lala

Parambassis lala "Highfin Glassfish"

The Highfin Glassfish is a small fish that is almost completely transparent. The organs and skeleton of the fish can easily be seen through its scales and flesh. The dorsal fin has two points, and gives the appearance of being two separate fins. The Highfin Glassfish is a peaceful, schooling fish that is best kept in groups of 6 or more. It can be kept with most smaller community species. However, it is timid, and easily harassed by larger, or more aggressive fish. It is relatively hardy as long as good water quality is maintained. The addition of some brackish salt to the water helps to reduce stress. However, they can be very sensitive to poor water conditions and cool water temperatures. Provide many hiding places using plants, driftwood, and other decorations. Highfin Glassfish will eat insect larvae, small crustaceans, and worms in their natural environment. In captivity, they will accept most flakes and small pellets, as well as frozen brine shrimp, daphnia, glassworms, and other meaty treats.

Aphyosemion australe

Aphyosemion australe "Chocolate Lyretail Killifish"

Male killies exhibit intense and beautiful coloration. These are no exception, and the color of their fins, in particular, really puts on a show for the ladies. This variant is characterized by the cocoa brown hue of their bodies, especially on the flanks and tail, that is normally golden in color. Like all killifish, they remain relatively small but have attitude to make up for their size. Avoid mixing multiple males in an aquarium as they will fight, but several females to one male (harem) are usually compatible in a larger aquarium. Keep lighting subdued in a killifish tank as these fish prefer a more dimly lit environment. They naturally live in "blackwater" environments with soft, acidic waters; many commercial extracts are available to help you maintain these conditions. Lots of plants and gentle water movement also help to replicate their natural environment. Killifish have naturally short lifespans and will usually not survive long after spawning. Most killies have lifespans of several months, up to just over a year. Spawning is sometimes triggered by environmental conditions like a change in temperature or pH. Research your choice carefully to make the most of your killifish population. This is a Restricted item and is not covered by our Arrive Alive 5 Day Guarantee.

Paracirrhites forsteri

Paracirrhites forsteri "Freckled Hawkfish" - Large

The Freckled Hawkfish has variable color. It is normally characterized by a mostly brownish body with dark freckles on the head and forebody. Two wide white or yellowish stripes may run along the dorsal and the sides. Hawkfish can be aggressive toward tank mates. They will eat small crabs, shrimp, and other crustaceans but are otherwise reef safe. Hawkfish do not directly eat or damage corals, but they lack the swim bladder of most fish and spend most of their time perching on a surface. A good diet for these fish consists of meaty frozen or prepared foods like brine shrimp, pellets, or small bits of foods like shrimp, scallop or squid. At its larger, adult size, the Freckled Hawkfish may also be given a very occassional live treat like ghost shrimp or feeder fish.

Paracirrhites arcatus

Paracirrhites arcatus "Arc-eye Hawkfish" - Small

The Arc-eyed Hawkfish has a light pinkish-brown body with a broad white stripe on each side that extends to the tail. They have a yellow and red arch-shaped marking behind the eye and three yellow dashes on the lower portion of the gill cover. To feel comfortable, Arc-eyed Hawkfish need plenty of rockwork to hide in and perch on. They can be somewhat aggressive toward other fish of the same size but will not do any serious harm. Arc-eyed Hawkfish are ideal for reef aquariums. Caution should be taken as they may eat small crusteaceans, fish, and shrimp. Arc-eyed Hawkfish do best on diet of live foods or frozen meaty foods.

Antennarius pictus

Antennarius pictus "Red Painted Frogfish"

The Painted Frogfish ( Antennarius pictus ) is highly variable in coloration and can be many colors and combinations of colors. Two of the most common in the aquarium trade are a solid black color with white fin tips and a bright red-orange color morph. This species is identified by a long, broad lure that can be up to twice as long as the dorsal spine behind it and has small, compressed appendages extending off of it. It also has some warty bumps on its body and usually has three spots on its tail. The common names "Anglerfish" and "Frogfish" are often used interchangeably. The fish available to the aquarium trade are very different from the deepwater Anglers featured in Disney's "Finding Nemo" that use a bright light to lure their prey. The Frogfish and Anglerfish for aquariums are found around reefs and rockwork where they blend in to ambush their prey. Like their deepwater counterparts, they do use a lure to attract prey but their lure looks more like a pom-pom or worm, depending on the species. These fish are often difficult to identify down to an exact species because of their very high variation in colors and patterns. They can also often change color and pattern to better blend in with their surroundings. With a few distinctive exceptions, most are extremely variable and may be different than the example pictured here. Anglers and Frogfish are ambush predators and can eat almost anything small enough to fit into their (very large) mouths. This can include other fish as well as inverts like crabs, shrimp and others. Use caution when choosing tankmates. These fish are not very active and can be kept in a fairly small tank (depending on species) and can be kept alone as a "species-only" showcase. They will typically eat almost any meaty foods offered but may only accept live items at first. Though they should be weaned onto frozen at some point, live ghost shrimp, mollies, guppies and similar items can be used at first. Eventually, they can be trained to accept frozen clam, squid, shrimp, krill and similar items. It is not unusual for these fish to fast the first few days to even weeks once introduced to a new environment or after a particularly large feeding.

Polypterus endlicheri endlicheri

Polypterus endlicheri endlicheri "Saddled Bichir" - Large

The Saddled Bichir is a long slender fish that is brown with evenly spaced black dorsal blotches. It has large, paddle shaped pectoral fins and a rounded tail. The dorsal fin is long with a serrated appearance from its many large spines. Because of their extremely large adult size, this fish should be kept in a tank that is wide and long, and at least 100 gallons to allow it to swim and maneuver easily. This fish is predatory, and will eat any fish that it can fit into its mouth. Otherwise, they are peaceful and can be kept with most large community species without trouble. Saddled bichirs should be kept singly unless the tank is large, as they will become aggressive with their own kind, competing for territory. They are also good jumpers. Choose an aquarium lid that is tight-fitting to prevent escape. Saddled bichirs are hardy fish as long as a regular water change schedule is maintained. They will accept a variety of foods including worms, crustaceans, and small fish, as well as pelleted or frozen meaty foods.

Thayeria boehlkei

Thayeria boehlkei "Penguin Tetra"

The Penquin Tetra, or Penguinfish, is easily recognized by the bold black line that runs through the mid-line of the fish and ends in the bottom section of the caudal fin. In the home aquarium, the silver body coloration will almost sparkle under tank lighting making for a very attractive fish for your aquarium. They are a schooling fish that should be kept in groups of at least 3 fish or more to thrive. Tank mates can include other tetras, guppies, mollies, swordtails, etc. These tetras should not be housed with barbs and gouramis as these fish are known to nip at the Penguin Tetra's fins. Penguin Tetras will accept most flake foods and small pellets. Frozen foods like blood worms, black worms, brine shrimp and daphnia can be offered occasionally and will help to enhance the tetras' coloration.

Astronotus ocellatus

Astronotus ocellatus "Red Oscar" - Small

Oscars are one of the most popular cichlids kept in aquariums. They have interesting personalities, their curiosity and lazy nature make them quite endearing. They are avid eaters and will accept pellet, frozen, and live foods, though live foods should be offered sparingly if at all. It is important to give them a varied diet so that they receive proper nutrition. A diet of strictly live feeder fish can lead to health and disease issues. Red Oscars are olive to brown with orange-red flanks. The orange-red coloration may be solid or have some dark spotting, and each fish varies. As juveniles they are not very aggressive, but they will become territorial and aggressive as they mature. There are very few differences between males and females, so sexing can be very difficult, particularly in young specimens. These fish require ample space, and single specimens should not be housed in tanks less than 55 gallons. Juveniles grow quickly and will easily outgrow aquariums that are smaller than recommended. They may be housed with other fish of similar temperament and size in large aquariums.

Aphyocharax anisitsi

Aphyocharax anisitsi "Bloodfin Tetra"

The Bloodfin Tetra has a silver body with bright red fins. It is a peaceful fish that will do best in a school of three or more. The Bloodfin Tetra is a suitable choice for a community tank. These tetras will eat a variety of foods, including flakes, bloodworms, and frozen food. When taken care of properly, this fish can live to over 10 years in captivity!

Puntius tetrazona

Puntius tetrazona "Albino Tiger Barb"

This is the albino form of the popular Tiger Barb. Instead of black bands on a tan body, it has white bands on a lighter toned orange-yellow body. The red coloration in the dorsal, caudal, and ventral fin is still present. This fish does not naturally exist in the wild and is the result of selective breeding. The albino Tiger Barb is a very attractive and hardy fish. As with the wild Tiger Barb, it has a tendency to nip the fins of long-finned tankmates and does best in schools of 6 or more. Barbs accept most aquarium foods like flakes, small pellets and a variety of small frozen foods like brine shrimp, daphnia, bloodworms and more.

Chaetodon ulietensis

Chaetodon ulietensis "False Double Saddle Butterfly" - Medium

The False Double-Saddle Butterfly ( Chaetodon ulietensis ) has two indistinct greyish saddles, and a smaller black band running through the fishes eye. The rear quarter of the fish is yellow, with a small black spot marking the base of the tail. It may also be referred to as the Pacific Double Saddle Butterflyfish This fish is often confused with Chaetodon falcula from the Indian Ocean, usually known as the "true" Double Saddle Butterfly or Blackwedge Butterfly. The area between the black saddles is yellow on C. falcula and white on C. ulietensis . The saddles themselves are usually crisper on C. falcula and blurrier on C. ulietensis . This butterfly is known to eat anemones as well as corals and some other inverts. Butterflyfish consist of a large number of fish found in the aquarium trade from the Chaetodon , Chelmon , Forcipiger , and Heniochus genuses, among others from the family Chaetodontidae . The family ranges in length from 3 inches up to close to 12 inches in length. Butterflies are usually roughly oval in body shape but longer fins make some appear elliptical or diamond-shaped. They resemble and are sometimes confused with angelfish (family Pomacentridae ) but angelfish have a cheekspine that is not found in butterflies. Butterflies are generally community fish in nature. Though some more pugnatious species may terrorize smaller or more docile fish, most can be kept with a wide range of community tankmates. Most butterfly species are not "reef safe" and will eat corals and polyps. In fact, some more delicate butterflies require corals as part of their natural diet. Butterflies may also harm smaller crustaceans (crabs and shrimp) and may pick at inverts like clams, feather dusters, anemones and similar tankmates. Use caution when introducing a butterfly into a tank with inverts; though some are considered "reef safe" by some aquarists, any butterfly may pose a risk to corals and inverts. The diet of butterflies can vary, as mentioned, based on what they normally eat in the wild. Some very picky species only pick at coral flesh and can be difficult to wean onto an aquarium-based diet. A very varied diet of algaes and meaty items like brine shrimp, mysis shrimp, scallops, clam, corals, sponges and other items is best. Vitamin supplements can also help get the butterflies all the nutrition they require. While some butterflies are very hardy and suitable for aquarists of all levels, more sensitive species should be attempted by experienced aquarists only.208310

Hyphessobrycon herbertaxelrodi

Hyphessobrycon herbertaxelrodi "Black Neon Tetra"

The Black Neon Tetra is a small fish that has a black belly with a gold stripe running horizontally down the middle of the fish. The upper body of the fish is greenish gold. They are small peaceful fish that can be kept with most other community species. Black Neon Tetras are hardy, and can be kept easily by the beginning aquarist. They accept flake and small pelleted food, as well as frozen brine shrimp and bloodworms. They are midwater swimmers and prefer food that floats or slowly sinks. Black Neon Tetras are schooling fish that should be kept in groups of 6 or more. Provide plenty of free swimming space, with some secluded areas using plants, driftwood and other decorations. This is a Restricted item and is not covered by our Arrive Alive 5 Day Guarantee.

Polypterus senegalus

Polypterus senegalus "Senegal Bichir" - Large

The Senegal Bichir is a long, slender fish, gray to light brown in color. It has large, paddle-like pectoral fins and a rounded tail. The dorsal fin is formed by a number of branched rays that run about 2/3 the length of the body and join the tail. Young Senegal Bichirs have vertical stripes that fade as they mature. This fish is predatory, and will eat any fish that it can fit into its mouth. However, they are peaceful with larger fish. This fish can be kept with most large community species without trouble. Senegal Bichirs should be kept singly unless the tank is large. They will become aggressive with their own kind and will frequently compete for territory. They are good jumpers. Choose an aquarium lid that is tight-fitting to prevent escape. Senegal Bichirs are hardy fish as long as a regular water change schedule is maintained. They will accept a variety of foods including worms, crustaceans, and small fish, as well as pelleted or frozen meaty foods.

Chaetodon lunula

Chaetodon lunula "Raccoon Butterfly" - Large

The Raccoon Butterfly ( Chaetodon lunula ) has black mask bordered by a thick white marking. There is a wide black band extending from the gill to the dorsal fin. The rest of the body is yellow, with dusky brown on the upper body, and dusky diagonal lines on the sides. Coloration varies with region and rare Hawaiian fish have a more vibrant coloration than those from other Indo-Pacific region. Another species in the Red Sea, C. fasciatus , is very similar in coloration with some minor differences. Butterflyfish consist of a large number of fish found in the aquarium trade from the Chaetodon , Chelmon , Forcipiger , and Heniochus genuses, among others from the family Chaetodontidae . The family ranges in length from 3 inches up to close to 12 inches in length. Butterflies are usually roughly oval in body shape but longer fins make some appear elliptical or diamond-shaped. They resemble and are sometimes confused with angelfish (family Pomacentridae ) but angelfish have a cheekspine that is not found in butterflies. Butterflies are generally community fish in nature.

A very varied diet of algaes and meaty items like brine shrimp, mysis shrimp, scallops, clam, corals, sponges and other items is best. Vitamin supplements can also help get the butterflies all the nutrition they require. While some butterflies are very hardy and suitable for aquarists of all levels, more sensitive species should be attempted by experienced aquarists only.

Polypterus delhezi

Polypterus delhezi "Banded Bichir"

The Banded Bichir is a long, slender fish that has a prehistoric appearance. The body is light brown to olive in color and most fish have a series of dark bars that adorn the dorsal side. It has large, paddle-shaped pectoral fins on which it will sometimes rest. The dorsal fin is made up of large connected spines that run almost the entire length of the body. The tail is wide and rounded. Banded Bichirs are predators and will consume any fish that they can swallow as well as pellets, worms, and other meaty foods. However, with larger tankmates, these fish are relatively passive. They can, however, be territorial toward their own kind, so be sure to keep them in a large tank if planning to keep more than one. They are also good jumpers, so be sure that the aquarium has a tight-fitting lid. Bichirs are hardy fish and easy to maintain as long as the aquarium is kept clean and the water quality pristine.

Antennarius sp.

Antennarius sp. "Patterned Angler" - XLarge

The common names "Anglerfish" and "Frogfish" are often used interchangeably. The fish available to the aquarium trade are very different from the deepwater Anglers featured in Disney's "Finding Nemo" that use a bright light to lure their prey. The Frogfish and Anglerfish for aquariums are found around reefs and rockwork where they blend in to ambush their prey. Like their deepwater counterparts, they do use a lure to attract prey but their lure looks more like a pom-pom or worm, depending on the species. These fish are often difficult to identify down to an exact species because of their very high variation in colors and patterns. They can also often change color and pattern to better blend in with their surroundings. With a few distinctive exceptions, most are extremely variable and may be different than the example pictured here. Many anglers and frogfish are identified by the shape of their esca (the "lure") and their illicium (the "fishing rod" part that holds up the lure). Anglers and Frogfish are ambush predators and can eat almost anything small enough to fit into their (very large) mouths. This can include other fish as well as inverts like crabs, shrimp and others. Use caution when choosing tankmates. These fish are not very active and can be kept in a fairly small tank (depending on species) and can be kept alone as a "species-only" showcase. They will typically eat almost any meaty foods offered but may only accept live items at first. Though they should be weaned onto frozen at some point, live ghost shrimp, mollies, guppies and similar items can be used at first. Eventually, they can be trained to accept frozen clam, squid, shrimp, krill and similar items. It is not unusual for these fish to fast the first few days to even weeks once introduced to a new environment or after a particularly large feeding.

Gymnocorymbus ternetzi

Gymnocorymbus ternetzi "Black Skirt Tetra"

The Black Skirt Tetra has two black bars on its sides. The posterior half of the body is generally black including the ventral fin. This tetra gets rather large and can become nippy to some small tank mates. Because of this, they should not be kept with very small or timid species. Black Skirt Tetras are otherwise safe for community tanks. They are schooling fish, and should be kept in groups of 6 or more. Provide plants, driftwood, or other decorations for cover. These fish are very hardy and are easy to keep even for the beginner. They can be fed flakes and small granular foods with the occasional frozen treat such as brine shrimp or blood worms.

Hyphessobrycon pulchripinnis

Hyphessobrycon pulchripinnis "Lemon Tetra"

The Lemon Tetra is dusky yellow in color with a black edge on the ventral fin and some black in the dorsal as well. They have bright red eyes and a bright yellow stripe to the first few rays of the ventral fin. Lemon tetras are schooling fish that should be kept in groups of at least 6 fish. They are carnivorous and will accept flake and small granular food. Occasional feedings of frozen or live bloodworms or brine shrimp are essential to maintaining their color. Lemon Tetras are peaceful and can be kept in most community aquariums. However, they are not as robust as other tetras and should be kept with fish that are smaller or of similar size. They can adapt to a variety of water conditions but prefer slightly acidic water. They make good candidates for the planted tank.

Rasbora heteromorpha

Rasbora heteromorpha "Harlequin Rasbora"

The harlequin rasbora is a silver to gold metallic fish with a wide black, roughly triangular mark that covers the rear half of the body. Reddish irridescent tones mark the upper "triangle" and flanks, and the fins usually have an orangeish tinge. A similar species, the false harlequin rasbora is often mistaken for the harlequin, but its black mark is shaped more like a lambchop. This fish is a hardy species that prefers acidic, soft water. It occurs in forest streams, and is most comfortable in an aquarium that has lower to moderate lighting and plenty of lush plant growth or other hiding places. This fish is schooling by nature, and should be kept in groups of at least 6 fish. It is peaceful and shy, and can easily be kept in most community tanks containing other small community fish. Avoid tankmates that are fast-swimming or nippy, as these will stress the harlequins. They can be fed a variety of flake and small pelleted foods, and well as frozen treats such as brine shrimp and daphnia.

Antennarius pictus

Antennarius pictus "Black Painted Frogfish"

The Painted Frogfish ( Antennarius pictus ) is highly variable in coloration and can be many colors and combinations of colors. Two of the most common in the aquarium trade are a solid black color with white fin tips and a bright red-orange color morph. This species is identified by a long, broad lure that can be up to twice as long as the dorsal spine behind it and has small, compressed appendages extending off of it. It also has some warty bumps on its body and usually has three spots on its tail. The common names "Anglerfish" and "Frogfish" are often used interchangeably. The fish available to the aquarium trade are very different from the deepwater Anglers featured in Disney's "Finding Nemo" that use a bright light to lure their prey. The Frogfish and Anglerfish for aquariums are found around reefs and rockwork where they blend in to ambush their prey. Like their deepwater counterparts, they do use a lure to attract prey but their lure looks more like a pom-pom or worm, depending on the species.

Rasbora trilineata

Rasbora trilineata "Scissortail Rasbora"

The Scissortail Rasbora is a very slender looking fish that will be silver in coloration with the characteristic black and white striped pattern in the tail that is common to this fish. They will get along with most other community fish, but do best in groups of 3 or more so that they can form schools. Diet consists of both flake and pellet food along with an occasional treat of frozen food such as bloodworms.

Astyanax mexicanus

Astyanax mexicanus "Blind Cave Tetra"

The Blind Cave Tetra is one of the most unique fish found in the freshwater aquarium. As the name implies, this fish has no eyes. Because their lives were spent in caves, their eyes were of no use to them and their body coloration faded, showing albino pink coloration only from the blood vessels beneath the skin. It is believed that they actually use sound waves to navigate their way throughout the aquarium. They will get along with many types of community fish such as tetras and barbs and are an incredibly hardy species. Blind Cave Tetras will accept flake, pellet and frozen food soon after being added to the aquarium.

Moenkhausia sanctaefilomenae

Moenkhausia sanctaefilomenae "Red Eye Tetra"

The Red Eye Tetra is a silver fish with a black bar at the base of the tail and red in the eyes. Moenkhausia sanctaefilomenae is practically identical to the slightly larger species Moenkhausia oligolepsis, and they may be found in schools together. Both are attractive schooling fish and are fairly robust. Because they are schooling fish they are best kept in groups of at least 6 fish. Red Eye Tetras are generally peaceful fish, and can be kept with most community species. They will accept most flake and small granular food as well as the occasional frozen brine shrimp or blood worms. Feeding frozen foods occasionally will help promote their best health and color. They can adapt to a variety of water conditions, but prefer slightly acidic water. They make good candidates for the planted tank.

Hyphessobrycon eques

Hyphessobrycon eques "Serpae Tetra"

The Serpae Tetra is one of the most colorful of the tetras. It has a red body that varies from pink to crimson. The dorsal and ventral fins are black with a slim white edge. There is also a black marking behind the gill on each side. They are small tetras, but very robust and can be kept with larger community fish without problems in many cases. Serpae tetras are schooling fish and should be kept in groups of 6 or more. They will accept flake and small granular foods. If fed the occasional frozen or live food and kept in a tank with a dark background the red color becomes more vibrant. They can adapt to a variety of water conditions but prefer slightly acidic water. They make good candidates for the planted tank.

Parambassis ranga

Parambassis ranga "Indian Glassfish"

The Indian Glassfish is a small fish that is almost completely transparent. The organs and skeleton of the fish can easily be seen through its scales and flesh. The dorsal fin has two points, and gives the appearance of being two separate fins. The Indian Glassfish is a peaceful, schooling fish that is best kept in groups of 6 or more. It can be kept with most smaller community species. However, it is timid, and easily harassed by larger, or more aggressive fish. It is relatively hardy as long as good water quality is maintained. The addition of some brackish salt to the water helps to reduce stress. However, they can be very sensitive to poor water conditions and cool water temperatures. Provide many hiding places using plants, driftwood, and other decorations. Indian glassfish will eat insect larvae, small crustaceans, and worms in their natural environment. In captivity, they will accept most flakes and small pellets, as well as frozen brine shrimp, daphnia, glassworms, and other meaty treats.

Astronotus ocellatus

Astronotus ocellatus "Albino Tiger Oscar" - Small

Oscars are one of the most popular cichlids kept in aquariums. They have interesting personalities, their curiosity and lazy nature make them quite endearing. They are avid eaters and will accept pellet, frozen, and live foods, though live foods should be offered sparingly if at all. It is important to give them a varied diet so that they receive proper nutrition. A diet of strictly live feeder fish can lead to health and disease issues. Albino Oscars are white with orange markings in contrast to the normal olive coloration of regular Oscars. As juveniles they are not very aggressive, but they will become territorial and aggressive as they mature. There are very few differences between males and females, so sexing can be very difficult, particularly in young specimens. These fish require ample space, and single specimens should not be housed in tanks less than 55 gallons. Juveniles grow quickly and will easily outgrow aquariums that are smaller than recommended. They may be housed with other fish of similar temperament and size in large aquariums.

Gymnocorymbus thayeri

Gymnocorymbus thayeri "False Black Tetra"

The False Black Tetra looks similar to its namesake, the Black Skirt Tetra, but its body is slightly more slender and the color not as distinct. They are native to the upper Amazon in Bolivia and Colombia. They are schooling fish, and should be kept in groups of 6 or more. Provide plants, driftwood, or other decorations for cover. These fish are very hardy and are easy to keep even for the beginner. They can be fed flakes and small granular foods with the occasional frozen treat such as brine shrimp or blood worms.

Moenkhausia pittieri

Moenkhausia pittieri "Diamond Tetra"

Diamond Tetras have a translucent body with a darker lateral line. The flanks shimmer with silvery scales under the light. Diamond Tetras dorsal and anal fins will be tipped in white which become more noticable as the fish matures in age. Like most other tetras they will eagerly eat both flake and pellet food soon after being introduced into the aquarium. They will get along with other tetra species but should be kept in groups of three or more to allow them to school together.

Puntius tetrazona

Puntius tetrazona "Green Tiger Barb" - Small

Green Tiger Barbs are a selectively bred color variant of the tiger barb. Like other tiger barbs, these fish can be kept in some community tanks, but should not be kept with long-finned or shy fish as they can be aggressive at times. Green Tiger Barbs are schooling fish and should be kept in groups of at least six fish. This will help to reduce aggressive behavior. Keeping barbs in a larger tank will also help to reduce fin-nipping and other aggressive behaviors. They will eat a variety of prepared foods like flake or small pellets, and will appreciate the occasional vegetable snack or frozen meaty food. They are fast swimmers and require a tank with ample open space.

Hemigrammus erythrozonus

Hemigrammus erythrozonus "Glowlight Tetra"

The Glowlight tetra is similar to the neon tetra, but not as colorful. It has grey-bronze body with a brilliant, iridescent, red stripe running horizontally from the eye to the tail. The tips of the fins are tinged in red and transparent. They are a schooling fish that are only comfortable if kept in groups of at least 6 fish. Glowlights will eat a variety of flake and small granular foods. They can be fed brine shrimp, bloodworms and other small frozen foods to enhance their bright red color and provide a balanced diet. Glowlight Tetras are peaceful fish that can be kept with most small to medium sized community species. They can adapt to a variety of water conditions, but prefer slightly acidic water. They make good candidates for the planted tank.

Pristella maxillaris

Pristella maxillaris "X-Ray Tetra"

The X-Ray tetra earns its name from its transparent body that makes its organs and bone structure clearly visible. The dorsal fin is black with a white tip and the caudal fin is red. They are a peaceful fish and can be kept in most community tanks. X-ray tetras are schooling fish and should be kept in groups of 6 or more for optimum health. They can be fed flake and small granular foods with the occasional frozen brine shrimp or bloodworms as a treat. Provide open areas in the tank for swimming as well as some hiding areas using plants, driftwood, or other decorations.

Puntius conchonius

Puntius conchonius "Neon Rosy Barb" - Small

Neon Rosy Barbs are a slightly bolder color variant of the common Rosy Barb. They are a hardy fish, and can be kept successfully by beginners. Male Rosy Barbs are usually metallic reddish-gold in color, females being solid gold. They both have a black spot near the base of the tail. Rosy Barbs may have a black tail and dorsal fin, or have long, flowing fins. Males are generally more colorful. . Rosy barbs are a schooling fish, and should be kept in groups of at least six fish. Some barbs can be fin nippers, especially with longer-finned fish. To curb this behavior, be sure to keep in a school of 6 or more! Barbs will accept a variety of foods, flake, small pellet, freeze-dried, and even frozen meaty foods and fresh vegetables.

Chaetodon ephippium

Chaetodon ephippium "Saddleback Butterfly" - Medium

The Saddleback Butterfly ( Chaetodon ephippium ) is a unique-looking butterfly. Its body is yellowish grey-blue with a black "saddle" outlined in white, yellow pelvic fins, an orange caudal fin, and orange markings around the face. They can be moderately aggressive and should not be kept with other butterflies. Butterflyfish consist of a large number of fish found in the aquarium trade from the Chaetodon , Chelmon , Forcipiger , and Heniochus genuses, among others from the family Chaetodontidae . The family ranges in length from 3 inches up to close to 12 inches in length. Butterflies are usually roughly oval in body shape but longer fins make some appear elliptical or diamond-shaped. They resemble and are sometimes confused with angelfish (family Pomacentridae ) but angelfish have a cheekspine that is not found in butterflies. Butterflies are generally community fish in nature. Though some more pugnatious species may terrorize smaller or more docile fish, most can be kept with a wide range of community tankmates. Most butterfly species are not "reef safe" and will eat corals and polyps. In fact, some more delicate butterflies require corals as part of their natural diet. Butterflies may also harm smaller crustaceans (crabs and shrimp) and may pick at inverts like clams, feather dusters, anemones and similar tankmates. Use caution when introducing a butterfly into a tank with inverts; though some are considered "reef safe" by some aquarists, any butterfly may pose a risk to corals and inverts. The diet of butterflies can vary, as mentioned, based on what they normally eat in the wild. Some very picky species only pick at coral flesh and can be difficult to wean onto an aquarium-based diet. A very varied diet of algaes and meaty items like brine shrimp, mysis shrimp, scallops, clam, corals, sponges and other items is best. Vitamin supplements can also help get the butterflies all the nutrition they require. While some butterflies are very hardy and suitable for aquarists of all levels, more sensitive species should be attempted by experienced aquarists only.

Puntius padamya

Puntius padamya "Odessa Barb"

The Odessa barb is a metallic fish, with coppery dorsal side and a lighter colored belly. They have two black spots on each side, and males are usually more colorful than females. Odessa barbs are generally peaceful, and can be kept in most community tanks with similar sized fish. They are a schooling fish, and should be kept in schools of at least six fish. Feed a variety of foods including flake, vegetable matter, and some frozen items.

Rasbora brittani

Rasbora brittani "Orange Spot Rasbora"

This slender, silver fish has large eyes, a deeply forked tail, and black and orange color at the base of the caudal fin. Rasbora are good community tank fish. They are schooling and should be kept in groups of 3 or more. Tankmates like barbs or tetras are fine. Feed a varied diet of flake, mini-pellets, and frozen foods. A planted tank is ideal for this fish. They are not overly sensitive to water quality.

Puntius denisonii

Puntius denisonii "Red Line Torpedo Barb" - Small

The beautifully colored Red Line Torpedo Barb is a relative newcomer to the aquarium trade. They are a slender, grey fish with a black horizontal stripe that runs from the gill plate to the caudal fin. A brilliant red stripe runs parallel to the black stripe, from the tip of the nose to about midway through the body. The same brilliant red appears on the dorsal fin, and the tail features two bright yellow spots. This fish will get along with species such as other barbs, gouramis, and freshwater sharks. They should accept most prepared foods, like flake or pellet, as well as the occasional frozen foods. They will also tend to nibble at soft-leaved plants. Planted tanks are however ideal to keep this barb, especially long tanks where they have plenty of room to swim. This is a Restricted item and is not covered by our Arrive Alive 5 Day Guarantee.

Hyphessobrycon ecuadorensis

Hyphessobrycon ecuadorensis "Columbian Tetra"

Columbian Tetras are peaceful fish that can add color to most community tanks. They are silvery in color with a blue-green iridescent sheen. The fins are pink to red. Males have a hooked anal fin and usually have more colorful finnage. Columbian Tetras are schooling fish, and are best kept in groups of 6 or more. They are generally peaceful fish, and can be kept in most community aquariums. Provide a planted or otherwise decorated tank to allow some areas for hiding. They will nibble on soft-leaved plants, so use thick-leaved plants if keeping these fish with live vegetation. They will accept a variety of flake and pelleted foods. If some frozen meaty foods such as brine shrimp and bloodworms are included in the diet this will help to intensify their coloration.

Characidium fasciatum

Characidium fasciatum "Darter Characin"

These interesting little members of the tetra family could be mistaken for a sucking loach or Siamese algae eater, with similar patterns and behavior. Unlike most characins, these are bottom dwelling that shuffle along the bottom of the tank foraging for small benthic inverts and other meaty tidbits to eat. They are peaceful, non-territorial fish that will eat frozen and dried foods in the home aquarium, and are fun to watch in a community setting. These fish prefer softer, slightly acidic water, good circulation and pristine water conditions.

Hemigrammus rodwayi

Hemigrammus rodwayi "Gold Tetra"

Gold Tetras are small Amazonian schooling tetras with shimmering metallic silver-gold bodies and a black dot at the base of the tail. They are peaceful community fish and active swimmers that tend to stay in tight groups when kept in numbers. Gold Tetras only reach a size of about 1 3/4 inches. These tetras tend to be hardy and handle a wide range of temp and pH. They will eat any variety of community foods like flake or granules. These fish are also sometimes known as the Brass Tetra, or under the scientific name Hemigrammus armstrongi . H. armstrongi is considered a synonym of H. rodwayi , however. Appearance and color can sometimes vary among Gold Tetras, depending on the region they were collected. The gold color on these fish comes from a chemical they produce known as guanine. Guanine gives it its shimmery gold color and can vary depending on the nutrition of the fish and may account for the multiple scientific names and common names.

Puntius nigrofasciatus

Puntius nigrofasciatus "Black Ruby Barb"

Black Ruby Barbs are characterized by a bright red head, and three or four black vertical bands. All fins are black, except for the tail, which is red. Males are generally more slender and more brightly colored than females. They are suitable for most community aquariums. Barbs are schooling fish and do best if kept in groups of six or more. Barbs accept a variety of foods including flake and small pellets, as well as frozen and freeze-dried. Barbs can be fin nippers, especially with long-finned fish. To help curb this behavior, be sure to keep them in schools.

Polypterus palmas buettikoferi

Polypterus palmas buettikoferi "Gold Dust Bichir"

The Gold Dust Bichir, or Buettikofer's Bichir, is a long, slender fish, that is light, yellow-brown in color with slighly darker brown markings. It has large, paddle-like pectoral fins and a rounded tail. The dorsal fin is formed by a 7-10 rays that run about 2/3 the length of the body and join the tail. They are imported from West Africa. This fish is predatory, and will eat any fish that it can fit into its mouth. However, they are peaceful with larger fish. This fish can be kept with most large community species without trouble. Bichirs should be kept singly unless the tank is large. They will become aggressive with their own kind and will frequently compete for territory. They are good jumpers. Choose an aquarium lid that is tight-fitting to prevent escape. Bichirs are hardy fish as long as a regular water change schedule is maintained. They will accept a variety of foods including worms, crustaceans, and small fish, as well as pelleted or frozen meaty foods.

Histrio histrio

Histrio histrio "Sargassum Angler" - Small

Sargassum Anglers ( Histrio histrio ) are usually striped brown and yellow and have skin flaps on their bodies to blend with the Sargassum macroalgae with which they are usually found floating. Patterns will vary between individual fish so no two will look exactly alike. The lures on these frogfish are very short and the pelvic fins and overall body shape are logner than other species. This is the only frogfish with a swim bladder and tends to be more buoyant and active than other species. The aquarium should be kept covered as these fish have been known to jump from the water if threatened. The common names "Anglerfish" and "Frogfish" are often used interchangeably. The fish available to the aquarium trade are very different from the deepwater Anglers featured in Disney's "Finding Nemo" that use a bright light to lure their prey. The Frogfish and Anglerfish for aquariums are found around reefs and rockwork where they blend in to ambush their prey. Like their deepwater counterparts, they do use a lure to attract prey but their lure looks more like a pom-pom or worm, depending on the species. These fish are often difficult to identify down to an exact species because of their very high variation in colors and patterns. They can also often change color and pattern to better blend in with their surroundings.

Anglers and Frogfish are ambush predators and can eat almost anything small enough to fit into their (very large) mouths. This can include other fish as well as inverts like crabs, shrimp and others. Use caution when choosing tankmates. These fish are not very active and can be kept in a fairly small tank (depending on species) and can be kept alone as a "species-only" showcase. They will typically eat almost any meaty foods offered but may only accept live items at first. Though they should be weaned onto frozen at some point, live ghost shrimp, mollies, guppies and similar items can be used at first. Eventually, they can be trained to accept frozen clam, squid, shrimp, krill and similar items. It is not unusual for these fish to fast the first few days to even weeks once introduced to a new environment or after a particularly large feeding.

Heniochus varius

Heniochus varius "Humphead Bannerfish" - Small

The Humphead Bannerfish ( Heniochus varius ) has a large hump above its head (which develops as the fish matures) and an elongated dorsal spine, giving the body a triangular shape. Its body is brown with white vertical bars at the back of the head and from the tip of the dorsal to the bottom base of the tail. Butterflyfish consist of a large number of fish found in the aquarium trade from the Chaetodon , Chelmon , Forcipiger , and Heniochus genuses, among others from the family Chaetodontidae . The family ranges in length from 3 inches up to close to 12 inches in length. Butterflies are usually roughly oval in body shape but longer fins make some appear elliptical or diamond-shaped. They resemble and are sometimes confused with angelfish (family Pomacentridae ) but angelfish have a cheekspine that is not found in butterflies. Butterflies are generally community fish in nature. Though some more pugnatious species may terrorize smaller or more docile fish, most can be kept with a wide range of community tankmates.

Heniochus acuminatus

Heniochus acuminatus "Longfin Bannerfish" - Large

The Longfin Bannerfish ( Heniochus acuminatus ) has two wide, forward sloping black bands across its white body. The rear parts of the dorsal, pectoral, and anal fins are yellow while the pelvic fins are black. The front ray of the dorsal fin is extended like a long banner. Several other Heniochus species have a very similar coloration with small variations. Among these variations, H. acuminatus can be identified by its white face and mouth and the white patch between the yellow area on the rear and the last black stripe. Butterflyfish consist of a large number of fish found in the aquarium trade from the Chaetodon , Chelmon , Forcipiger , and Heniochus genuses, among others from the family Chaetodontidae . The family ranges in length from 3 inches up to close to 12 inches in length. Butterflies are usually roughly oval in body shape but longer fins make some appear elliptical or diamond-shaped. They resemble and are sometimes confused with angelfish (family Pomacentridae ) but angelfish have a cheekspine that is not found in butterflies. Butterflies are generally community fish in nature. Though some more pugnatious species may terrorize smaller or more docile fish, most can be kept with a wide range of community tankmates. Most butterfly species are not "reef safe" and will eat corals and polyps. In fact, some more delicate butterflies require corals as part of their natural diet. Butterflies may also harm smaller crustaceans (crabs and shrimp) and may pick at inverts like clams, feather dusters, anemones and similar tankmates. Use caution when introducing a butterfly into a tank with inverts; though some are considered "reef safe" by some aquarists, any butterfly may pose a risk to corals and inverts. The diet of butterflies can vary, as mentioned, based on what they normally eat in the wild. Some very picky species only pick at coral flesh and can be difficult to wean onto an aquarium-based diet. A very varied diet of algaes and meaty items like brine shrimp, mysis shrimp, scallops, clam, corals, sponges and other items is best. Vitamin supplements can also help get the butterflies all the nutrition they require. While some butterflies are very hardy and suitable for aquarists of all levels, more sensitive species should be attempted by experienced aquarists only.217366

Chaetodon semilarvatus

Chaetodon semilarvatus "Golden Butterflyfish" - Medium

The Golden Butterflyfish ( Chaetodon semilarvatus ) is also known as the Semilarvatus Butterfly or Bluecheek Butterfly. It has a deep golden-yellow body color with thin, vertical stripes and a blue patch around each eye. They are found only in the Red Sea and Gulf of Aden. Butterflyfish consist of a large number of fish found in the aquarium trade from the Chaetodon , Chelmon , Forcipiger , and Heniochus genuses, among others from the family Chaetodontidae . The family ranges in length from 3 inches up to close to 12 inches in length. Butterflies are usually roughly oval in body shape but longer fins make some appear elliptical or diamond-shaped.

Chaetodon collare

Chaetodon collare "Redtail Butterflyfish" - Large

The Redtail Butterfly ( Chaetodon collare , also known as the Collare Butterfly or Pakistan Butterfly) is dark grey-brown with pale cream-colored scale centers, a vertical white collar behind the eye and a red tail. This butterfly is best kept alone; more than one in the same tank will usually fight. Butterflyfish consist of a large number of fish found in the aquarium trade from the Chaetodon , Chelmon , Forcipiger , and Heniochus genuses, among others from the family Chaetodontidae . The family ranges in length from 3 inches up to close to 12 inches in length. Butterflies are usually roughly oval in body shape but longer fins make some appear elliptical or diamond-shaped.

Puntius conchonius

Puntius conchonius "Red Glass Rosy Barb"

Glass Rosy Barbs are a slightly muted color variant of the common Rosy Barb. The color is pale and almost transluscent. They are a hardy fish, and can be kept successfully by beginners. Male Rosy Barbs are usually reddish-gold in color, females being more yellow-gold. They both have a black spot near the base of the tail. Rosy Barbs may have a black tail and dorsal fin, or have long, flowing fins. Males are generally more colorful. Rosy barbs are a schooling fish, and should be kept in groups of at least six fish. Some barbs can be fin nippers, especially with longer-finned fish. To curb this behavior, be sure to keep in a school of 6 or more! Barbs will accept a variety of foods, flake, small pellet, freeze-dried, and even frozen meaty foods and fresh vegetables.

Hyphessobrycon flammeus

Hyphessobrycon flammeus "Orange Flame Tetra"

The "standard" Von Rio tetra has a pink to red posterior portion of the body and 2 gray or black bars on its side just behind the gills. This variant has been developed through selective breeding and has more intense orange coloration. They are a small peaceful species that can be kept in community tanks with other small fish. They will accept flake and small granular foods and the addition of frozen brine shrimp or bloodworms to their diet will enhance their bright color. These fish are relatively hardy if kept in proper conditions. Von Rio tetras are schooling fish, and should be kept in groups of at least 6. Being a slightly shy species plenty of cover should be added to the aquarium to allow them places to hide. Driftwood, ornaments, live plants, and plastic plants are the most common things used.

Forcipiger flavissimus

Forcipiger flavissimus "Yellow Longnose Butterfly" - Small

The Yellow Longnose Butterfly ( Forcipiger flavissimus ) is bright yellow with a black triangle on the upper part of the head. The lower jaw is white, the caudal fin is clear, and there is a false eye spot on the anal fin. They are also considered by some to be "Reef Safe" as they may not usually bother corals but as with any butterflies, this can be risky. They are known to feed on a wide range of small inverts and crustaceans, including the tube feet of echinoderms like urchins and starfish. Another species is sometime also available as the Yellow Longnose Butterfly, F. longirostris . This species has identical coloration but a noticeably longer snout that can approach the fish's entire body length in relative length. The snout on F. flavissimus is usually about half the length of the body. F. longirostris also has small black spots on its throat/chin area. Butterflyfish consist of a large number of fish found in the aquarium trade from the Chaetodon , Chelmon , Forcipiger , and Heniochus genuses, among others from the family Chaetodontidae . The family ranges in length from 3 inches up to close to 12 inches in length. Butterflies are usually roughly oval in body shape but longer fins make some appear elliptical or diamond-shaped.

Histrio histrio

Histrio histrio "Sargassum Angler" - Large

Sargassum Anglers ( Histrio histrio ) are usually striped brown and yellow and have skin flaps on their bodies to blend with the Sargassum macroalgae with which they are usually found floating. Patterns will vary between individual fish so no two will look exactly alike. The lures on these frogfish are very short and the pelvic fins and overall body shape are logner than other species. This is the only frogfish with a swim bladder and tends to be more buoyant and active than other species. The aquarium should be kept covered as these fish have been known to jump from the water if threatened. The common names "Anglerfish" and "Frogfish" are often used interchangeably. The fish available to the aquarium trade are very different from the deepwater Anglers featured in Disney's "Finding Nemo" that use a bright light to lure their prey. The Frogfish and Anglerfish for aquariums are found around reefs and rockwork where they blend in to ambush their prey. Like their deepwater counterparts, they do use a lure to attract prey but their lure looks more like a pom-pom or worm, depending on the species. These fish are often difficult to identify down to an exact species because of their very high variation in colors and patterns. They can also often change color and pattern to better blend in with their surroundings. With a few distinctive exceptions, most are extremely variable and may be different than the example pictured here. Many anglers and frogfish are identified by the shape of their esca (the "lure") and their illicium (the "fishing rod" part that holds up the lure). Anglers and Frogfish are ambush predators and can eat almost anything small enough to fit into their (very large) mouths. This can include other fish as well as inverts like crabs, shrimp and others. Use caution when choosing tankmates. These fish are not very active and can be kept in a fairly small tank (depending on species) and can be kept alone as a "species-only" showcase. They will typically eat almost any meaty foods offered but may only accept live items at first. Though they should be weaned onto frozen at some point, live ghost shrimp, mollies, guppies and similar items can be used at first. Eventually, they can be trained to accept frozen clam, squid, shrimp, krill and similar items. It is not unusual for these fish to fast the first few days to even weeks once introduced to a new environment or after a particularly large feeding.

Arnoldichthys spilopterus

Arnoldichthys spilopterus "African Red-eye Tetra"

African Red-eye Tetras are also known by several other common names including Arnold's tetra and the Niger Tetra. These Red-Eyed Characins Can grow to about 4" in length and prefer a meaty diet. These fish are native to the lower Niger and Ogun rivers of Nigeria and they should be kept in groups of 5 or more. They willl need ample space. These fish have beautiful coloration with two lateral stripes, one pale orange, the other blue-green. The upper part of eye is red, giving the fish its name. The scales below the lateral line are large and noticeable. Males and females can be distinguished by the color of the anal fin.

Crenuchus spilurus

Crenuchus spilurus "Sailfin Tetra"

The Sailfin Tetra or Sailfin Characin is a solitary and secretive species from South America. Unlike most tetras these fish are often alone instead of travelling in schools. The maost distinguishing feature is the elongated dorsal fin. This is a fast moving species whith a predatory nature, though its prey is not usually other fish, but small copepods, larvae and crustaceans. It will need a meaty diet in the aquarium and should not be housed with very small tankmates. If you are fortunate enough to have these fish spawn in captivity, you'll see that it is the male that tends the spawned eggs.

Poecilia reticulata

Poecilia reticulata "Turquoise Lyretail Guppy" - Male

Turquoise Lyretail Guppies are light silvery-blue and may have faint markings on their bodies. The tail has a solid light blue bar at the top and bottom with longer edges and is clear through the center, giving them a forked "lyretail" appearance. Guppies are a popular fish for aquariums because of their bright colors and the long flowing fins of the males. While wild guppies are usually plain silver, the fancy guppies bred for the aquarium trade can be a variety of colors and combinations. Pattern and coloration can vary slightly even within a specific variety of fancy guppies due to their selective breeding. Males have long fan-shaped tails and long dorsal fins. Females are less colorful, and lack the elaborate fins but can grow slightly larger. Guppies are peaceful fish and can be kept in most community aquariums. Because of their long finnage, fish that have a tendency to nip at fins, such as barbs, would not be appropriate tankmates. Guppies do well in planted aquariums and need good water quality. They can be sensitive to changes in their environment in parameters like temperatures and pH. Guppies are omnivores and can be fed most tropical freshwater aquarium foods like flakes and very small pellets as well as frozen foods like brine shrimp, Cyclopeeze, Spirulina, mosquito larvae and similar items. Guppies are live bearing fish, and will usually reproduce frequently in the home aquarium. The adult guppies and other fish may eat the young fry, so they should be placed in a breeder trap or a nursery tank until they are larger. Guppies can be sexed by the shape of the gonopodium, the specialized anal fin just in front of the tail. Males will have a pointed, tube-like gonopodium while the gonopodium on females is typically flaired and fan-shaped. This is a Restricted item and is not covered by our Arrive Alive 5 Day Guarantee.

Hasemania nana "Silvertip Tetra"

The Silvertip Tetra has a yellow to gold body with white tips to all the fins. The base of the tail is black. Some fish have a patch of iridescent gold running in a line from the tail to the midline of the fish. They are active swimmers that should have plenty of free swimming space. Also provide a few hiding areas using rocks, plants, and driftwood. These fish form schools, and should be kept in groups of at least 6 fish in order to minimize stress. Silvertip Tetras can be fed flake and small granular foods. They are a hardy tetra and will do well in most community tanks.

Garra lissorhynchus

Garra lissorhynchus "Redtail Garra"

Redtail Garras are a species native mainly to India. They have elongated golden brown bodies with darker markings and a red-orange hue in the tail. They have a sucker mouth and will usually be found on the bottom surfaces of their environment. These fish are realtively peaceful and may ne housed in a community aquarium. Be sure to provide planty of rocks and wood for the fish to cling to and hide amongst, as well as adequate water movement. Feed the Redtail Garra a varied diet. They will feed on algae and detritus in the aquarium, but supplementing their diet with algae wafers and frozen foods and pellets of bloodworms and similar items will improve their nutrition.

Chaetodon lunula

Chaetodon lunula "Raccoon Butterfly" - Medium

The Raccoon Butterfly ( Chaetodon lunula ) has black mask bordered by a thick white marking. There is a wide black band extending from the gill to the dorsal fin. The rest of the body is yellow, with dusky brown on the upper body, and dusky diagonal lines on the sides. Coloration varies with region and rare Hawaiian fish have a more vibrant coloration than those from other Indo-Pacific region. Another species in the Red Sea, C. fasciatus , is very similar in coloration with some minor differences. Butterflyfish consist of a large number of fish found in the aquarium trade from the Chaetodon , Chelmon , Forcipiger , and Heniochus genuses, among others from the family Chaetodontidae . The family ranges in length from 3 inches up to close to 12 inches in length. Butterflies are usually roughly oval in body shape but longer fins make some appear elliptical or diamond-shaped. They resemble and are sometimes confused with angelfish (family Pomacentridae ) but angelfish have a cheekspine that is not found in butterflies. Butterflies are generally community fish in nature. Though some more pugnatious species may terrorize smaller or more docile fish, most can be kept with a wide range of community tankmates. Most butterfly species are not "reef safe" and will eat corals and polyps. In fact, some more delicate butterflies require corals as part of their natural diet. Butterflies may also harm smaller crustaceans (crabs and shrimp) and may pick at inverts like clams, feather dusters, anemones and similar tankmates. Use caution when introducing a butterfly into a tank with inverts; though some are considered "reef safe" by some aquarists, any butterfly may pose a risk to corals and inverts. The diet of butterflies can vary, as mentioned, based on what they normally eat in the wild. Some very picky species only pick at coral flesh and can be difficult to wean onto an aquarium-based diet. A very varied diet of algaes and meaty items like brine shrimp, mysis shrimp, scallops, clam, corals, sponges and other items is best. Vitamin supplements can also help get the butterflies all the nutrition they require. While some butterflies are very hardy and suitable for aquarists of all levels, more sensitive species should be attempted by experienced aquarists only.

Hyphessobrycon bentosi

Hyphessobrycon bentosi "Ornate Tetra"

Ornate Tetras are also called Robert's Tetras in the trade. They are grey or reddish in color with black-tipped fins. They are small peaceful fish that can be kept with most other community species. These tetras are hardy, and can be kept easily by the beginner aquarist. They accept flake and small pelleted food, as well as frozen brine shrimp and bloodworms. They are midwater swimmers and prefer food that floats or slowly sinks. Ornate Tetras are schooling fish that should be kept in groups of 6 or more. Provide plenty of free swimming space, with some secluded areas using plants, driftwood and other decorations.

Puntius denisonii

Puntius denisonii "Red Line Torpedo Barb" - Medium

The beautifully colored Red Line Torpedo Barb is a relative newcomer to the aquarium trade. They are a slender, grey fish with a black horizontal stripe that runs from the gill plate to the caudal fin. A brilliant red stripe runs parallel to the black stripe, from the tip of the nose to about midway through the body. The same brilliant red appears on the dorsal fin, and the tail features two bright yellow spots. This fish will get along with species such as other barbs, gouramis, and freshwater sharks. They should accept most prepared foods, like flake or pellet, as well as the occasional frozen foods. They will also tend to nibble at soft-leaved plants. Planted tanks are however ideal to keep this barb, especially long tanks where they have plenty of room to swim. This is a Restricted item and is not covered by our Arrive Alive 5 Day Guarantee.

Hyphessobrycon megalopterus

Hyphessobrycon megalopterus "Black Phantom Tetra"

Black Phantom Tetras are gray in color with black fins. A black vertical bar marks the body just behind the gill. The fins become elongated as the fish matures. Black phantom tetras are relatively hardy fish that are suitable for most community aquariums. They prefer medium to dimly lit tanks with plenty of plants or other decorations to hide in. Avoid very bright lighting, as this will make the fish nervous. They are schooling fish and should be kept in groups of at least 6 fish. Black Phantom Tetras will accept a variety of flake and small pelleted foods as well as frozen treats such as brine shrimp and blood worms.

Polypterus ornatipinnis

Polypterus ornatipinnis "Ornate Bichir" - Small

The Ornate Bichir is a primitive-looking fish that has a round, eel-like body and a long, deeply serrated dorsal fin that meets the tail. The body is marbled black, gray, and white. Its black and white striped pectoral fins are large and paddle shaped. These large fins are frequently used to support the body when resting. The caudal fin is rounded. Two tube shaped growths extend from the nostrils, giving it the appearance of a mythical dragon. This interesting fish is a nocturnal predator, and will consume insect larvae, small worms, crustaceans, and small fish. It can normally be trained to accept pellets and frozen foods without too much effort. It is relatively peaceful with tankmates that are too large to be swallowed. It can, however, be aggressive with its own kind, so be sure to provide enough territory for all if keeping more than one. Though it is able to reach 2 feet in length, it usually does not exceed 18 inches in captivity. The ornate bichir is a hardy fish that can be easily kept in the home aquarium. Provide some caves, planted areas, or rock crevices for daytime hiding places. Be sure that the lid is tight-fitting as these fish are excellent jumpers.

Hyphessobrycon flammeus

Hyphessobrycon flammeus "Flame Tetra"

The Flame or Von Rio Tetra has a pink to red posterior portion of the body and 2 gray or black bars on its side just behind the gills. They are a small peaceful species that can be kept in community tanks with other small fish. They will accept flake and small granular foods and the addition of frozen brine shrimp or bloodworms to their diet will enhance their bright color.

Xenomystus nigri

Xenomystus nigri "Black African Knifefish"

The African Knifefish is a gray to black fish that, as its name suggests, is shaped like a knife. It has no dorsal or caudal fins, and its anal fin extends from below the gill area to the tip of the tail. This fish has the interesting ability to produce barking sounds. It is a nocturnal species that will hide during the day and come out at night to feed. This fish is tolerant of other species, but can be timid, so do not keep it with fast-swimming or nippy fish. It may harass very small fish. The African knife will accept most meaty foods including worms, brine shrimp, and snails. It can be trained to accept prepared foods. This fish is sensitive to poor water quality, so provide efficient filration and regular water changes.

Chitala chitala

Chitala chitala "Clown Knifefish" - Small

The Clown Knifefish is very beautiful and graceful, though it grows very large! A shimmering silver color, it's most noticable feature would be the almost perfectly circular spots toward the fishes' rear end. These spots increase and size and number as the fish matures. This fish can be difficult to keep due to it's large adult size. It will eat any fish that can fit in its mouth, and actually prefers live food above all else. It is rather difficult to switch them to frozen. This fish is fragile when juvenile, so be sure to keep up with maintenance during the youth of this fish. Adult, or semi-adult specimens require a very large tank. Adults are territorial and will find a spot and stick to it. They require some kind of cave or tube for hiding, and they enjoy a planted tank with lots of floating varieties. Though it is big, it is docile. Tank mates should be large enough that they won't be eaten, and they should also be on the calm side.

Chitala chitala

Chitala chitala "Clown Knifefish" - Large

The Clown Knife is a large predator that spends much of its time hiding during the day. They have flattened bodies with dark spots. These fish become very big and need a very large, well-filtered aquarium. They are not necessarily aggressive but they will eat any fish small enough to fit into their mouths.

Jordanella floridae

Jordanella floridae "American Flagfish"

The American Flagfish is an attractive killifish with a coloration vaguely reminiscent of the American flag. In males, the body is light colored with an irridescent blue-green sheen. Numerous horizontal red, broken lines mark its flanks. A darker blotch marks the center of the body just below the dorsal fins. Females are tan and duller in color, with shorter fins and some dark mottling on the sides. Flagfish are peaceful fish that can be kept with most community species. However, they can be territorial with their own kind. They are best kept in pairs, or one male with a few females. Unlike many killifish, these fish are very hardy, and can be easily kept and bred in the home aquarium. Provide a heavily planted aquarium with subdued lighting. These fish will accept a variety of foods including small worms, crustaceans, insects, plant matter such as spinach or lettuce, as well as pellets and flakes. American flagfish are primarily freshwater fish, but they are known to enter brackish water, and can be kept successfully in brackish water tanks. They are sensitive to high temperatures, so keep them with temperate species that will tolerate slightly lower temperatures. This is a Restricted item and is not covered by our Arrive Alive 5 Day Guarantee.

Inlecypris auropurpurea

Inlecypris auropurpurea "Lake Inle Danio"

Sometimes called Tiger rasboras, Lake Inle Danios are very slender fish and have vertical black bars that run the length of the fish from the operculum to the caudal peduncle. This fish is a hardy species that prefers neutral to slightly alkaline water. It occurs in heavily planted marshes and swamps, and is most comfortable in an aquarium that has plenty of lush plant growth. This fish is schooling by nature, and should be kept in groups of at least five fish. Tiger Rasboras are known to nip at the fins of slower moving fish and should only be kept with fish of the same tempermant. Such fish include barbs, rainbow fish, and giant danios. They can be fed a variety of flake and small pelleted foods, and well as frozen treats such as brine shrimp and daphnia.

Steatogenys duidae

Steatogenys duidae "Centipede Knifefish"

Centipede Knifefish are an attractive species, with slender, graceful bodies and rich brown and tan banded coloration. This fish will generally ignore other fish, though they may try to eat much smaller fish, like neon tetras. They can be kept with other fish that have gentle, non-aggressive dispositions and willl not harass this timid knife.They do require some live food in their diet, be it ghost shrimp, guppies, or worms. They should accept frozen food and if you are patient, eventually pellets.A large tank with plenty of cover is best. They would enjoy a planted tank.

Cirrhitops fasciatus

Cirrhitops fasciatus "Redbarred Hawkfish"

The Redbarred Hawkfish ( Cirrhitops fasciatus ) has bright red bands and speckles on a white body. It grows to a modest size at around 5 inches and is common in the waters around the Hawaiian Islands. Hawkfish can be aggressive towards tank mates. They will eat small crabs, shrimp, and other crustaceans, but are otherwise reef safe. Hawkfish do not directly eat or damage corals, but they lack the swim bladder of most fish and spend most of their time perching on a surface. A good diet for these fish consists of meaty frozen or prepared foods like brine shrimp, pellets, or small bits of foods like shrimp, scallop or squid. At its larger adult size, the Banded Hawkfish may also be given a very occassional live treat like ghost shrimp or feeder fish.216123

Cirrhitichthys aureus

Cirrhitichthys aureus "Golden Hawkfish"

This golden yellow Hawkfish reaches a length of 5 inches and makes a nice addition to a fish-only tank. Hawkfish lack the swim bladder of most fish and spend time perching on rockwork. They naturally eat shrimp, crabs, and very small fish, but are otherwise reef safe. Hawkfish may get aggressive towards smaller fish and will aggressively defend their area from other hawkfish and other fish as they age.

Cirrhitichthys oxycephalus

Cirrhitichthys oxycephalus "Pixie Hawkfish"

The Pixie Hawkfish has white or pink base color with red-brown blotches on the body and fins. Hawkfish are peaceful toward other fish but may eat very small fish if they can catch them. They are also generally safe for reef aquariums, but may eat small crabs and shrimp. Hawkfish do best on a diet of small meaty frozen foods and live foods. They may also accept sinking pellet food. In order to mimic the environment that these fish live in there should be plenty of rock work in the tank.

Paracirrhites forsteri

Paracirrhites forsteri "Freckled Hawkfish" - Small

The Freckled Hawkfish has variable color. It is normally characterized by a mostly brownish body with dark freckles on the head and forebody. Two wide white or yellowish stripes may run along the dorsal and the sides. Hawkfish can be aggressive toward tank mates. They will eat small crabs, shrimp, and other crustaceans but are otherwise reef safe. Hawkfish do not directly eat or damage corals, but they lack the swim bladder of most fish and spend most of their time perching on a surface. A good diet for these fish consists of meaty frozen or prepared foods like brine shrimp, pellets, or small bits of foods like shrimp, scallop or squid. At its larger, adult size, the Freckled Hawkfish may also be given a very occassional live treat like ghost shrimp or feeder fish.

Cirrhitichthys aprinus

Cirrhitichthys aprinus "Spotted Hawkfish"

The Spotted or Threadfin Hawkfish has a dark spot on the gill cover and its whitish body is otherwise covered in red or brown bars and blotches. Hawkfish are reef safe though they may eat small crabs, shrimp, and other crustaceans. They can be aggressive toward tank mates. Hawkfish do not directly eat or damage corals, but they lack the swim bladder of most fish and spend most of their time perching on a surface. A good diet for these fish consists of meaty frozen or prepared foods like brine shrimp, pellets, or small bits of foods like shrimp, scallop or squid. At its larger, adult size, the Threadfin Hawkfish may also be given a very occasional live treat like ghost shrimp or feeder fish.

Cirrhitichthys falco

Cirrhitichthys falco "Dwarf Hawkfish"

The Dwarf or Falco Hawkfish has two brown saddle shaped bars on the front of its white body and two red bars below the eye. Small red-brown blotches develop into stripes over the back, fading into a white underside. The dorsal spines are tipped with "cirri"-tiny tufts that branch off at the top. An interesting fish to watch, they always appear very curious. A diet of live, frozen, and flake or pellet will suit this hawkfish. They may eat small crabs, shrimp, or other crustaceans but are otherwise reef safe.

Betta splendens

Betta splendens "Siamese Fighting Fish"- Doubletail Male

Bettas are one of the most beautiful of all the anabantoids (gouramis, or "air-breathers"). Their ability to breathe air directly from the atmosphere enables them to live in the stagnant pools and puddles in which they naturally occur. The bettas seen in stores today are very different from the wild types. Throughout the years the betta has been bred for longer fins and intense colors. They are very different from the short finned, mostly brown, wild bettas. Doubletail Bettas are bred to have a forked tail with two "lobes" instead of the traditional one. Bettas have evolved a very intense territorial aggression to the point where they are best kept by themselves. They do not tolerate other males and females are only tolerated when breeding. This natural behavior and their ability to breathe atmospheric air makes them ideal for keeping in bowls and small aquaria. As long as the water is kept relatively warm and is changed regularly, they do very well. Bettas are carnivorous fish and must be fed meaty foods. There are many special prepared Betta diets (flake/pellet) that are excellent foods. Blood worms, brine shrimp, and plankton are also excellent as treats. Keep in mind that a betta has a stomach about the size of it's eye. It should be fed an eyeful every day to maintain it's shape and health. It is very popular to keep bettas in a flower vase with a terrarium plant like the peace lily. This is an excellent setup for the fish but the water must be changed weekly or more and the fish fed regularly to keep it healthy. You must also keep a fair amount of space between the water level and top of the vase, because bettas need an open space to breathe atmospheric air. Also, BETTAS DO NOT EAT THE ROOTS OF THE PLANT! This is a popular misconception about this particular setup. If you happen to see your betta nibbling the roots, this is probably just out of starvation (if you aren't feeding it) or boredom. There are many names for the particular betta color patterns but most are variations of blue and/or red colors. If you are looking for a specific coloration, contact a livestock department representative or simply allow us to choose one of our favorites for you! Betta fish may not be shipped to California.

Aplocheilus lineatus

Aplocheilus lineatus "Gold Wonder Killifish"

The Gold Wonder Killifish is a slender fish with brilliant yellow coloration. Females and juveniles are not quite as bright. This fish has its yellow color due to selective breeding. This is one of the larger and hardier killifish. It is also longer-lived than most, some reaching the ripe old age of four years. It is carnivorous, and prefers to feed at the water's surface. This preference reflects its natural diet, as it feeds on insects, fish fry, and other small animals that fall in the water or congregate near the surface. The Gold Wonder Killifish is a peaceful fish that can be kept in most community aquariums. However, do not keep them in tanks containing young fry, as they will enthusiastically eat the baby fish. Feed a variety of meaty foods including small pellets, flake, and frozen. This is a Restricted item and is not covered by our Arrive Alive 5 Day Guarantee.

Rasbora borapetensis

Rasbora borapetensis "Brilliant Rasbora"

Brilliant Rasboras are schooling fish native to Thailand and Malaysia. They are attractive fish especially when kept in schools. They have a light brown dorsal area, and a white belly, the two regions being separated by a black stripe running along the lateral line. The base of the tail is bright red. These fish find security in numbers. They prefer a tank that is densely planted with dim areas. Rasboras are safe for community tanks, but are timid and should not be kept with bold or nippy tankmates. They will eat flake foods or small granules as a staple diet.

Amblycirrhitus pinos

Amblycirrhitus pinos "Red-spotted Hawkfish"

The Redspotted Hawkfish has a whitish body with irregular brown bars, with two that are nearly black near the base of the tail. There is a thick splattering of red dots on the head through the gill area. The dorsal has tassels on the tips and red dots throughout. Hawks are reef safe though they may eat small crustaceans and fish. They can be aggressive toward tank mates. Hawkfish do not directly eat or damage corals, but they lack the swim bladder of most fish and spend most of their time perching on a surface. A good diet for these fish consists of meaty frozen or prepared foods like brine shrimp, pellets, or small bits of foods like shrimp, scallop or squid. At its larger, adult size, the Redspotted Hawkfish may also be given a very occassional live treat like ghost shrimp or feeder fish.

Fundulopanchax gardneri gardneri

Fundulopanchax gardneri gardneri "Steel Blue Killifish"

This is a beautiful killifish with vibrant red and blue coloration. Like all killifish, they remain relatively small but have attitude to make up for their size. Avoid mixing multiple males in an aquarium as they will usually fight but females or a harem mix is usually compatible in a larger aquarium. Keep lighting subdued in a killifish tank as these fish prefer a more dimly lit environment. They naturally live in "blackwater" environments with soft, acidic waters; many commercial extracts are available to help you maintain these conditions. Lots of plants and gentle water movement also help to replicate their natural environment. Killifish have naturally short lifespans and will usually not survive long after spawning. Most killies have lifespans of several months, up to just over a year. Spawning is sometimes triggered by environmental conditions like a change in temperature or pH. Research your choice carefully to make the most of your killifish population. This is a Restricted item and is not covered by our Arrive Alive 5 Day Guarantee.

Neocirrhites armatus

Neocirrhites armatus "Flame Hawkfish"

The Flame Hawkfish has a bright red body with a black stripe down the dorsal side and a little bit of black behind the eyes. Though reef safe, Hawkfish can be aggressive toward tank mates and will eat crabs, shrimp, and other crustaceans. Hawkfish do not directly eat or damage corals, but they lack the swim bladder of most fish and spend most of their time perching on a surface, waiting for their next meal. This may damage or irritate some corals. A good diet for these fish consists of meaty frozen or prepared foods like brine shrimp, pellets, or small bits of foods like shrimp, scallop or squid. At its larger, adult size, the Flame Hawkfish may also be given a very occasional live treat like ghost shrimp or feeder fish.

Leptobarbus hoevenii

Leptobarbus hoevenii "Mad Barb"

The Mad Barb, also known as the Red Fin Cigar Shark, is a very active swimmer and is best kept in a long tank with plenty of room to "stretch its fins". They have been known to jump from uncovered aquariums when startled so keep the tank covered at all times. Also, keep decorations free from sharp edges that this barb may bump against and be injured by. These are schooling fish and are best kept in groups, as space allows.

Forcipiger flavissimus

Forcipiger flavissimus "Yellow Longnose Butterfly" - XLarge

The Yellow Longnose Butterfly ( Forcipiger flavissimus ) is bright yellow with a black triangle on the upper part of the head. The lower jaw is white, the caudal fin is clear, and there is a false eye spot on the anal fin. They are also considered by some to be "Reef Safe" as they may not usually bother corals but as with any butterflies, this can be risky. They are known to feed on a wide range of small inverts and crustaceans, including the tube feet of echinoderms like urchins and starfish. Another species is sometime also available as the Yellow Longnose Butterfly, F. longirostris . This species has identical coloration but a noticeably longer snout that can approach the fish's entire body length in relative length. The snout on F. flavissimus is usually about half the length of the body. F. longirostris also has small black spots on its throat/chin area. Butterflyfish consist of a large number of fish found in the aquarium trade from the Chaetodon , Chelmon , Forcipiger , and Heniochus genuses, among others from the family Chaetodontidae . The family ranges in length from 3 inches up to close to 12 inches in length. Butterflies are usually roughly oval in body shape but longer fins make some appear elliptical or diamond-shaped. They resemble and are sometimes confused with angelfish (family Pomacentridae ) but angelfish have a cheekspine that is not found in butterflies. Butterflies are generally community fish in nature. Though some more pugnatious species may terrorize smaller or more docile fish, most can be kept with a wide range of community tankmates. Most butterfly species are not "reef safe" and will eat corals and polyps. In fact, some more delicate butterflies require corals as part of their natural diet. Butterflies may also harm smaller crustaceans (crabs and shrimp) and may pick at inverts like clams, feather dusters, anemones and similar tankmates. Use caution when introducing a butterfly into a tank with inverts; though some are considered "reef safe" by some aquarists, any butterfly may pose a risk to corals and inverts. The diet of butterflies can vary, as mentioned, based on what they normally eat in the wild. Some very picky species only pick at coral flesh and can be difficult to wean onto an aquarium-based diet. A very varied diet of algaes and meaty items like brine shrimp, mysis shrimp, scallops, clam, corals, sponges and other items is best. Vitamin supplements can also help get the butterflies all the nutrition they require. While some butterflies are very hardy and suitable for aquarists of all levels, more sensitive species should be attempted by experienced aquarists only.

Paracirrhites forsteri

Paracirrhites forsteri "Freckled Hawkfish" - Medium

The Freckled Hawkfish has variable color. It is normally characterized by a mostly brownish body with dark freckles on the head and forebody. Two wide white or yellowish stripes may run along the dorsal and the sides. Hawkfish can be aggressive toward tank mates. They will eat small crabs, shrimp, and other crustaceans but are otherwise reef safe. Hawkfish do not directly eat or damage corals, but they lack the swim bladder of most fish and spend most of their time perching on a surface. A good diet for these fish consists of meaty frozen or prepared foods like brine shrimp, pellets, or small bits of foods like shrimp, scallop or squid. At its larger, adult size, the Freckled Hawkfish may also be given a very occassional live treat like ghost shrimp or feeder fish.
