Cypriniformes is an order of ray-finned fish, which includes many families and genera of cyprinid fish, such as barbs, gobies, loaches, botias, and minnows. Cypriniformes is an "order-within-an-order", placed under the superorder Ostariophysi—which is also made up of cyprinid, ostariophysin fishes. The order contains 11–12 families, over 400 genera, and more than 4,250 named species; new species are regularly described, and new genera are recognized frequently. Cyprinids are most diverse in South and Southeast Asia, but are entirely absent from Australia and South America. At 112 years old, the longest-lived cypriniform fish documented is the bigmouth buffalo.
The giant danio is a tropical fish belonging to the minnow family Cyprinidae. Originating in Sri Lanka, Nepal, and the west coast of India, this species grows to a maximum length of 4–6 inches (10–15 cm), making it one of the largest of the danionins. It is characterized by a blue and yellow, torpedo-shaped body with gray and clear fins.
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.
Microrasbora is a genus of small fishes. The generic name means "small Rasbora", however these are more closely related to the danios than rasboras. They inhabit freshwater in Myanmar and Yunnan, China.
Danionella is a genus of danionin fish found in freshwater habitats in Myanmar and West Bengal, India. It includes some of the smallest fishes.
Devario auropurpureus is a small species of danionin fish endemic to Lake Inle in Myanmar. It is a schooling species associated with submerged vegetation. It is harvested for aquarium trade, and usually sold under the older name Inlecypris auropurpurea. This species has also been found for sale under the common name "Lake Inle Trout Danio" in some tropical fish retailers.
The harlequin rasbora is a small fish in the family Cyprinidae. The species became an instant favorite among aquarists after its introduction in the early 1900s and is the best known and most widely kept species among the rasboras. In 1935, an image of a trio of harlequin rasboras, stamped in 14k gold, would grace the cover of the first edition of William T. Innes's classic Exotic Aquarium Fishes and would remain so through all 19 editions.
Danio is a genus of small freshwater fish in the family Cyprinidae found in South and Southeast Asia, commonly kept in aquaria. They are generally characterised by a pattern of horizontal stripes, rows of spots or vertical bars. Some species have two pairs of long barbels. Species of this genus consume various small aquatic insects, crustaceans and worms.
Paedocypris is a genus of tiny cyprinid fish found in swamps and streams on the Southeast Asian islands of Borneo, Sumatra and Bintan.
The eyespot rasbora is a small fish belonging to the Family Cyprinidae, subfamily Danioninae, which is known by the common names of ocellated rasbora, hi-spot rasbora, and eye-spot rasbora, an allusion to the marking situated upon the dorsal fin. This small fish is a popular aquarium fish, having been one of the species featured in the landmark textbook Exotic Aquarium Fishes by Dr William T. Innes. Its appearance in this work only occurs in later editions of the book, however, therefore the species is not subject to the same degree of aquarium domestication as the more familiar harlequin rasbora.
Microdevario kubotai is a species of cyprinid found in southeast Asian rivers and streams. It belongs to the genus Microdevario, which contains small danionins. The type locality is in Ranong Province, Peninsular Thailand. It is also known from the adjacent Phang Nga Province and the Ataran basin in Myanmar. It likely occurs elsewhere in the region and an introduced population exists in the Songgaria River. It reaches up to 1.9 cm (0.75 in) in length, the maximum length can reach 2.5 cm (0.98 in).
Danio erythromicron, often known as emerald dwarf danio and emerald dwarf rasbora, is a species of cyprinid fish which is endemic to Inle Lake in Myanmar.
The dracula fish is a species of tropical danionin fish from the cyprinid family. It is a freshwater fish endemic to Myanmar. A close relative is Danio rerio, the zebrafish of aquariums. It is named dracula after its unusual "fangs"; male dracula fish have protruding tooth-like bones stemming from their jawbones. Males have been observed using their fangs to spar with other males.
The White Cloud Mountain minnow is a hardy species of freshwater fish and coldwater fish often kept in an aquarium. The species is a member of the carp family of the order Cypriniformes, native to China. The White Cloud Mountain minnow is practically extinct in its native habitat, due to pollution and tourism. It was believed to be extinct for over 20 years in 1980, but an apparently native population of this fish was discovered on Hainan Island, well away from the White Cloud Mountain. They are bred in farms and are easily available through the aquarium trade. However, inbreeding in farms has led to genetically weak stock that is vulnerable to disease and prone to physical deformities.
The Odessa barb is a species of cyprinid fish known from Central Myanmar, where it is known to occur in an artificial pond above the Anisakan Falls and also from the lower Chindwin River. For many years it has been known to the aquarium hobby, where it has frequently been confused with the less colourful ticto barb, but it was only described scientifically in 2008.
Boraras brigittae is a species of ray-finned fish in the genus Boraras, also known as chili rasboras or mosquito rasboras, are a very small species of fishes native to the swamps of South West Borneo, Indonesia.
The danionins are a group of small, minnow-type fish belonging to the family Cyprinidae. Species of this group are in the genera clades Danio and Devario, based on the latest phylo-genetic research by Fang et al in 2009. They are primarily native to the fresh waters of South and Southeast Asia, with fewer species in Africa. Many species are brightly coloured and are available as aquarium fish worldwide. Fishes of the danio clade tend to have horizontal stripes, rows of spots, or vertical bars, and often have long barbels. Species within the devario clade tend to have vertical or horizontal bars, and short, rudimentary barbels, if present at all. All danionins are egg scatterers, and breed in the rainy season in the wild. They are carnivores, living on insects and small crustaceans.
Red dwarf rasbora is a species of cyprinid found endemic to Lake Inle in Shan State in Myanmar. It belongs to the genus Microrasbora, which contains two small species of danionins.
