Cypriniformes is an order of ray-finned fish, including the carps, minnows, loaches, and relatives. Cypriniformes is an Order within the Superorder Ostariophysi consisting of "Carp-like" Ostariophysins. This order contains 11-12 families, although some authorities have designated as many as 23, over 400 genera, and more than 4,250 species, with new species being described every few months or so, and new genera being recognized frequently. They are most diverse in southeastern Asia, and 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.
The hillstream loaches or river loaches are a family, the Balitoridae, of small fish from South, Southeast and East Asia. The family includes about 202 species. They are sometimes sold as "lizardfish" or "flossensaugers". Many of the species are popular for aquaria, species in the genus Sewellia are most commonly sold in the aquaria trade. They have a number of similarities with the Cobitidae, their sibling family of "loaches", such as multiple barbels around the mouth. They should not be confused with the loricariids, which look similar but are a family of catfish.
Pangio is a genus of small Asian freshwater fish in the true loach family Cobitidae. In earlier taxonomic schemes it was known as Acanthophthalmus. The "kuhli loach" is well-known in the aquarium trade and commonly identified as P. kuhlii, but most individuals actually appear to be P. semicincta.
The clown loach, or tiger botia, is a tropical freshwater fish belonging to the botiid loach family. It is the sole member of the genus Chromobotia. It originates in inland waters in Indonesia on the islands of Sumatra and Borneo. In Sentarum, West Borneo that fish named: ulanguli. It is a popular fish in the freshwater aquarium trade and is sold worldwide.
Botia is a genus of freshwater fish in the loach family (Botiidae). It was a large genus with about 20 species. In 2004 Maurice Kottelat proposed in his paper to divide the genus into four related genera based on fish appearance and locality:
The pond loach, also known as the Dojo loach, oriental weatherloach or oriental weatherfish, is a freshwater fish in the loach family Cobitidae. They are native to East Asia, but are also popular as an aquarium fish and introduced elsewhere in Asia and to Europe, America and Australia. The alternate name weather loach is shared with several other Cobitidae, including the other members of the genus Misgurnus and the spotted weather loach. This term comes from their ability to detect changes in barometric pressure before a storm and react with frantic swimming or standing on end.
Yasuhikotakia is a genus of botiid loaches, many which are popular aquarium fish. It is named in honor of Japanese collector/researcher Dr. Yasuhiko Taki. This genus has been separated from the genus Botia in the paper by Maurice Kottelat in 2004.
Cobitis is a genus of small freshwater fish in the family Cobitidae from temperate and subtropical Eurasia. It contains the "typical spiny loaches", including the well-known spined loach of Europe. Similar spiny loaches, occurring generally south of the range of Cobitis, are nowadays separated in Sabanejewia.
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.
Pangio anguillaris is a species of loach found in still and slow-moving freshwater in Indochina, Malay Peninsula, Sumatra, and Borneo.
Botiidae is a family of cypriniform ray-finned fishes from South, Southeast, and East Asia. Until recently they were placed in the true loach family Cobitidae, until Maurice Kottelat revised the loaches and re-elevated this taxon to family rank in 2012. The family includes about 56 species.
Acantopsis dialuzona is a loach native to the swift, clear streams and rivers of mainland and archipelagic Southeast Asia, Indonesia,Peninsular Malaysia,Thailand,but Southeast Asia outside its range, including as Acantopsis. A. choirorhynchos because of the lack of taxonomic resolution in Acantopsis. It can also be found in flooded fields.
Acantopsis octoactinotos, the long-nosed loach, is a freshwater fish from Indonesia, commonly found in aquariums.
The true Kuhli loach, occasionally referred to as eel loach, is a small eel-like freshwater fish belonging to the loach family (Cobitidae). They originate from the island of Java in Indonesia. This snake-like creature is very slender and nocturnal.
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.
Lepidocephalus is a genus of loaches native to rivers in the Southeast Asian countries of Indonesia, Malaysia and Thailand and Manipur, north east India. Members of this genus are known as "spirit loaches". They resemble the related kuhli loaches and Lepidocephalichthys loaches, but are more robust and generally found deep in large rivers. With little or no light in their habitat, their eyes and pigmentation are reduced to various extent. One species, L. spectrum, completely lacks pigment and eyes, similar to cavefish. They are generally poorly known, but based on the relatively few scientific museum specimens they can reach up to 8 cm (3.1 in) in standard length.
Vaillantella maassi, the forktail loach, is a species of loach in the family Vaillantellidae, a monogeneric family with two other species, Vaillantella cinnamomea and Vaillantella euepiptera. They are from Southeast Asia.
Lepidocephalichthys hasselti is a species of cobitid loach native to southeastern Asia and western Indonesia. This species reaches a length of 45 millimetres (1.8 in) TL.
Paracanthocobitis is a genus, or subgenus, of freshwater fish in the family Nemacheilidae. This genus is known from the Indus basin in Pakistan to the Mekong basin of Cambodia and Laos The type species is Paracanthocobitis zonalternans. Some authorities treat this as a subgenus of Acanthocobitis
