Marine angelfish are perciform fish of the family Pomacanthidae. They are found on shallow reefs in the tropical Atlantic, Indian, and mostly western Pacific Oceans. The family contains seven genera and about 86 species. They should not be confused with the freshwater angelfish, tropical cichlids of the Amazon Basin.
The tinfoil barb is a tropical Southeast Asian freshwater fish of the family Cyprinidae. This species was originally described as Barbus schwanenfeldii by Pieter Bleeker in 1853, and has also been placed in the genera Barbodes and Puntius. The specific epithet is frequently misspelled schwanefeldii.
The tiger barb or Sumatra barb, is a species of tropical cyprinid fish. The natural geographic range reportedly extends throughout the Malay Peninsula, Sumatra and Borneo in Indonesia, with unsubstantiated sightings reported in Cambodia. Tiger barbs are also found in many other parts of Asia, and with little reliable collection data over long periods of time, definite conclusions about their natural geographic range versus established introductions are difficult. Tiger barbs may sometimes be confused with Puntigrus anchisporus, Puntigrus navjotsodhii, or Puntigrus partipentazona, which are similar in appearance, the only differences being the slightly different stripe pattern and the number of scales these fish have.
The three spot gourami, also known as the opaline gourami, blue gourami, and gold gourami, is a species of fish native to southeastern Asia, but also introduced elsewhere. This gourami gets its name from the two spots along each side of its body in line with the eye, considered the third spot. This species is of minor commercial importance as a food fish in its native range and is also farmed. It is also popular in the aquarium trade. The species reaches 15 cm in standard length.
The red-tailed black shark, also known as the redtail shark, red tailed shark, and redtail sharkminnow, is a species of tropical freshwater fish in the carp family, Cyprinidae. It’s named after its shark like appearance and movement, as well as its distinctive red tail. Despite its name, it is more closely related to carp. It is endemic to streams and rivers in Thailand and is currently critically endangered. However, it is common in aquaria, where it is prized for its deep black body, and vivid red orange tail. These are moderately sized tropical aquarium fish who are active benthic swimmers. They are omnivorous but are willing to scavenge if the opportunity arises. They are known for their activity as well as their temperament towards other fish. The red-tailed black sharks seen in the aquarium trade today are all captive bred.
The foxface rabbitfish, also known as the foxface, black-face rabbit fish, badger fish or the common foxface is a species of marine ray-finned fish, a rabbitfish belonging to the family Siganidae. It is found in the Indian and Pacific Oceans. It can be found in the aquarium trade.
The redtail catfish, is a large species of South American pimelodid (long-whiskered) catfish. It is known in Venezuelan Spanish as cajaro; in Guyana, it is known as a banana catfish, and in Brazil it is known as pirarara, a fusion of words from the indigenous Tupi language: pirá and arara. It is the only extant species of its genus, Phractocephalus.
The royal gramma, also known as the fairy basslet, is a species of fish in the family Grammatidae native to reef environments of the tropical western Atlantic Ocean. They are commonly kept in aquariums.
The fire eel is a relatively large species of spiny eel. This omnivorous freshwater fish is native to Southeast Asia but is also found in the aquarium trade. Although it has declined locally due to overfishing, it remains common overall.
The Siamese algae-eater is a species of freshwater fish in the carp family, Cyprinidae. This bottom-dwelling tropical fish is found in mainland Southeast Asia, including the Chao Phraya and Mekong basins as well as the Malay Peninsula. Its natural habitats are streams and rivers as well as flooded forests during the rainy season. The Siamese algae-eater should not be confused with the flying fox or the false siamensis , lacking the distinctive black bands of the former.
Algae eater or algivore is a common name for any bottom-dwelling or filter-feeding aquatic animal species that specialize in feeding on algae and phytoplanktons. Algae eaters are important for the fishkeeping hobby and many are commonly kept by aquarium hobbyists to improve water quality. They are also important primary consumers that relay the biomass and energy from photosynthetic autotrophes up into the food web, as well as protecting the aquatic ecosystem against algae blooms.
The snakeskin gourami is a species of gourami native to Southeast Asia. Prior to the merging of Belontidae to the family Osphronemidae, the snakeskin gourami was regarded as the largest member of its family. It is still the largest species in its genus and subfamily.
The rainbow shark is a species of Southeast Asian freshwater fish from the family Cyprinidae. It is also known as the ruby shark, red-fin shark, red-finned shark, rainbow sharkminnow, green fringelip labeo, whitefin shark and whitetail sharkminnow. It is a popular, semi-aggressive aquarium fish. Unlike true sharks, which belong to the Chondrichthyes lineage, the rainbow shark is an actinopterygiian.
Epalzeorhynchos is a small ray-finned fish genus of the family Cyprinidae. Its members are – like some other cyprinids – known as "freshwater sharks" or simply "sharks". They are, however, freshwater members of the Osteichthyes lineage which is distinct from the Chondrichthyes lineage of sharks. The description of these animals as "shark" is most likely a reference to the shark-like shape of these popular cyprinids.
The violet goby is a species of goby native to marine, fresh and brackish waters near the Atlantic coast of North and South America from South Carolina in the United States of America, to northern Brazil. It prefers bays, estuaries and river mouths with muddy substrates. It is often marketed as the dragon goby or dragon fish.
Nematobrycon palmeri, commonly known as the emperor tetra, is a species of characid fish found in the Atrato and San Juan river basins in western Colombia. It was first imported in the aquarium trade to the United States in 1960 and has since become well established.
Gyrinocheilus aymonieri is a freshwater fish native to large parts of Southeast Asia. It is of interest as a local food source and for the aquarium trade. Its common names include honey sucker, sucking loach and Chinese algae eater.
Gyrinocheilus is the single genus in the family Gyrinocheilidae, a family of small Southeast Asian cypriniform fishes that live in fast-flowing freshwater mountain streams. The species in this genus are commonly called algae eaters. They hold on to fixed objects using a sucker-like mouth, and, despite the name, feed on a wide range of detritus, rather than simply on algae. A "golden" variety of G. aymonieri, the Chinese algae eater or "sucking loach", can be found in many pet shops and fish farms.
The giant gourami is a species of large gourami native to freshwater habitats in Southeast Asia. It has also been introduced elsewhere. The species is commercially important as a food fish and is also farmed. It can be found in the aquarium trade, as well. The species has been used for weed control on highly invasive aquatic plants like Salvinia molesta, as the giant gourami can be a voracious herbivore.
Crossocheilus langei, also known as the red algae eater, is a species of ray-finned fish in the genus Crossocheilus. It is native to Malaysia and Sumatra. This bottom-dwelling tropical fish is found in mainland Southeast Asia. Its natural habitats are streams and rivers as well as flooded forests during the rainy season. It is often confused with the Crossocheilus oblongus, however, both are algae eaters and will behave similarly.
