Cyprinidae is a family of freshwater fish commonly called the carp or minnow family, including the carps, the true minnows, and their relatives the barbs and barbels, among others. Cyprinidae is the largest and most diverse fish family, and the largest vertebrate animal family overall, with about 3,000 species; only 1,270 of these remain extant, divided into about 200 valid genera. Cyprinids range from about 12 mm in size to the 3 m (9.8 ft) giant barb. By genus and species count, the family makes up more than two-thirds of the ostariophysian order Cypriniformes. The family name is derived from the Greek word kyprînos.
Micropterus is a genus of North American freshwater fish collectively known as the black bass, belonging to the sunfish family Centrarchidae of order Perciformes. They are sometimes erroneously called "black trout", but the name trout more correctly refers to certain members of the salmonid family.
Puntius is a genus of small freshwater fish in the family Cyprinidae native to South Asia and Mainland Southeast Asia, as well as Taiwan.
Rasbora is a genus of fish in the family Cyprinidae. They are native to freshwater habitats in South and Southeast Asia, as well as southeast China. A single species, R. gerlachi, is only known from an old specimen that reputedly originated from Africa (Cameroon), but this locality is considered doubtful. They are small, up to 17 cm (6.7 in) long, although most species do not surpass 10 cm (4 in) and many have a dark horizontal stripe.
The Lake Kurumoi rainbowfish is a species of freshwater rainbowfish in the subfamily Melanotaeniinae. It was endemic to West Papua in Indonesia. Its natural habitat was only the small Lake Kurumoi in the Bird's Head Peninsula. It is primarily threatened by habitat loss, however it is unknown if the wild population still exists as it has probably been extirpated from its entire native range.
Neosalanx is a genus of icefishes native to Eastern Asia, ranging from Korea, through Japan and China, to Vietnam. They inhabit coastal marine waters, estuaries and river basins. There are both species that are threatened and species that are widespread.
Oryzias is a genus of ricefishes native to fresh and brackish water in east and south Asia. Some species are widespread and the Japanese rice fish is commonly used in science as a model organism, while others have very small ranges and are threatened. They are small, up to 8 cm (3.1 in) long, and most are relatively plain in colour.
The stone moroko, also known as the topmouth gudgeon, is a fish belonging to the Cyprinid family, native to Asia, but introduced and now considered an invasive species in Europe and North America. The fish's size is rarely above 8 cm and usually 2 to 7.5 cm long.
Betta is a large genus of small, active, often colorful, freshwater ray-finned fishes, in the gourami family (Osphronemidae). The best known Betta species is B. splendens, commonly known as the Siamese fighting fish and often kept as an aquarium pet.
Eels are ray-finned fish belonging to the order Anguilliformes, which consists of eight suborders, 20 families, 164 genera, and about 1000 species. Eels undergo considerable development from the early larval stage to the eventual adult stage and are usually predators.
Clidoderma is a genus of righteye flounders containing one extant species and two described fossil species from Japan.
The Catostomidae are the suckers of the order Cypriniformes, with about 78 species in this family of freshwater fishes. The Catostomidae are almost exclusively native to North America. The only exceptions are Catostomus catostomus, found in both North America and Russia, and Myxocyprinus asiaticus found only in China. In the Ozarks they are a common food fish and a festival is held each year to celebrate them. The bigmouth buffalo, Ictiobus cyprinellus, can reach an age up to 127 years, making it the oldest known freshwater teleost by more than 50 years.
Cirrhinus molitorella is a species of ray-finned fish in the genus Cirrhinus found mainly in southern China and Vietnam.
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.
Lefua is a genus of stone loaches native to East Asia.this genus have Barbels at their mouths and their nostrils. Some other traits typically found in this family are their bodies are round column, swimming well.
Metzia is a genus of cyprinid fish that is found in eastern Asia. The genus is named in honor of the American ichthyologist Charles William Metz of Stanford University.
Nipponocypris is a genus of cyprinid fish containing three extant species, one endemic to Japan, one to South Korea while the third occurs in Japan, Korea and China. A fourth, extinct species is known from Middle Pleistocene-aged freshwater strata from the Kusu Basin in Japan.
Macropodus is a genus of small to medium-sized labyrinth fish native to freshwater habitats in eastern Asia. Most species are restricted to southern China and Vietnam, but M. opercularis occurs as far north as the Yangtze basin, and M. ocellatus occurs north to the Amur River, as well as in Japan and Korea. In China, they are often used for fights, so they are named Chinese bettas because of their similarity to the genus Betta. A few species in the genus are regularly seen in the aquarium trade, and M. opercularis has been introduced to regions far outside its native range.
Pseudorasbora pugnax is a species of cyprinid fish endemic to Honshu, Japan.
Pseudorasbora pumila, also known as the moroco, is a species of cyprinid fish endemic to Japan.
