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.
Cobitidae, also known as the True loaches, is a family of Old World freshwater fish. They occur throughout Eurasia and in Morocco, and inhabit riverine ecosystems. Today, most "loaches" are placed in other families. The family includes about 260 described species. New species are being described regularly.
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.
Pseudolaguvia is a genus of South Asian river catfishes. These species inhabit hill streams and large rivers. P. tenebricosa is found in fast running, clear water; the river has a sandy bottom and numerous rocks and boulders and aquatic vegetation is absent. P. inornata is from clear, shallow, moderately flowing streams with a predominantly sandy bottom. P. muricata is found in clear, shallow, slow-flowing streams with a mixed substrate of sand and detritus; these fish are found amongst detritus in areas with current. P. ferula is also found in swift flowing waters with a mixed rocky/sandy bottom.
Glyptothorax is a genus of catfishes order Siluriformes of the family Sisoridae. It is the most species-rich and widely distributed genus in the family with new species being discovered on a regular basis. These species are distributed in the Black Sea basin, northern Turkey, south and east to the Yangtze River drainage in China and south throughout Indo-China to Java, Indonesia. They are found in Asia Minor and southwards to Southeast Asia. The genus is very diverse in the Indian subcontinent. Southeast Asian species tend to have restricted distributions.
Garra is a genus of fish in the family Cyprinidae. These fish are one example of the "log suckers", sucker-mouthed barbs and other cyprinids commonly kept in aquaria to keep down algae. The doctor fish of Anatolia and the Middle East belongs in this genus. The majority of the more than 160 species of garras are native to Asia, but about one-fifth of the species are from Africa.
Schistura is a genus of fish in the stone loach family Nemacheilidae native to the streams and rivers of the southern and eastern Asia. Some of these species are troglobitic.
Amblyceps is a genus of fish in the family Amblycipitidae. The genera Amblyceps and Liobagrus are sister group pair that is, in turn, sister to Xiurenbagrus. These species are easily distinguished by the presence of pinnate processes along with the median caudal-fin rays, a prominent cup-like skin flap above the base of the pectoral spine, and the adipose fin largely separate from the caudal fin. In most species the caudal fin is deeply forked; A. apangi and A. murraystuarti differ in having their caudal fin truncate. Amblyceps species may reach about 100 millimetres (3.94 in) SL.
The least rasbora or exclamation point rasbora is a species of ray-finned fish in the genus Boraras, native to freshwater habitats in mainland southeast Asia. This species is very small, ranging from 12 to 16 mm.
Loaches are fish of the superfamily Cobitoidea. They are freshwater, benthic (bottom-dwelling) fish found in rivers and creeks throughout Eurasia and northern Africa. Loaches are among the most diverse groups of fish; the 1249 known species of Cobitoidea comprise about 107 genera divided among 9 families.
Physoschistura is a genus of fish in the family Nemacheilidae found mostly in Southeast Asia.
Pethia is a genus of small freshwater fish in the family Cyprinidae native to South Asia, East Asia and Mainland Southeast Asia. Some species are commonly seen in the aquarium trade. The name Pethia is derived from the Sinhalese "pethia", a generic word used to describe any of several small species of cyprinid fishes. Most members of this genus were included in Puntius, until it was revised in 2012.
Psilorhynchus nudithoracicus also known as the rainbow minnow is a freshwater ray-finned fish, a torrent minnow, which is found in the drainage systems of the Ganges and the Brahmaputra in India, Nepal and Bangladesh, as well as the Meghna River and Surma River drainage basins in India and Bangladesh. the habitat of this species is shallow running streams with sandy bottoms, usually with some pebbles laying on the sand. This species reaches a length of 8.4 cm (3.3 in).
