Erromyzon is a genus of fish in the family Gastromyzontidae endemic to China and Vietnam. [1]
There are currently 5 recognized species in this genus:
Cypriniformes is an order of ray-finned fish, including the carps, minnows, loaches, and relatives. 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.
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.
Sinocyclocheilus is a genus of freshwater fish in the family Cyprinidae endemic to China, where only found in Guangxi, Guizhou and Yunnan. Almost all of its species live in or around caves and most of these have adaptions typical of cavefish such as a lack of scales, lack of pigmentation and reduced eyes. Several species have an unusual hunchbacked appearance and some of the cave-dwellers have a "horn" on the back, the function of which is unclear. In contrast, the Sinocyclocheilus species that live aboveground, as well as a few found underground, show no clear cavefish adaptions. They are relatively small fish reaching up to 23 cm (9.1 in) in length. The individual species have small ranges and populations, leading to the status of most of the evaluated species as threatened. Many species populations in the genus have yet to be evaluated by the IUCN.
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.
Oreonectes is a genus of fish in the family Nemacheilidae found in the rivers and cave of Asia. Many of these species are troglobitic.
Protocobitis is a genus of loaches endemic to Guangxi in China and living in caves.
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.
Sinogastromyzon is a genus of hillstream loaches native to eastern Asia.
Triplophysa is a genus of fish in the family Nemacheilidae found mainly in and around the Qinghai-Tibet Plateau in China. Currently, the genus is a mixed assemblage of species. Some lineages have been identified and treated as subgenera, but as Wikipedia follows Fishbase for fish species these have been treated as subgenera in Wikipedia, although Kottelat and the Catalog of Fishes treat them as genera. FishBase, however, includes these in Triplophysa without specifying subgenera and treats the names given by Kottelat as synonyms.
Yunnanilus is a genus of small stone loaches that are endemic to southeastern China, especially Guangxi and Yunnan. They are found in rivers, streams and lakes; some species are restricted to caves.
Balitora is a genus of fish in the family Balitoridae endemic to Asia.
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.
Homatula is a genus of stone loaches endemic to China.
Liniparhomaloptera is a genus of fish in the family Gastromyzontidae found in China and Vietnam.
Metahomaloptera is a small genus of hillstream loaches endemic to China.
Vanmanenia is a genus of loaches from China and mainland Southeast Asia.
Parabotia is a genus of loaches. Most species in the genus are endemic to China, but P. curtis is from Japan, P. dubius is from Vietnam, and P. mantschuricus is from the Amur River basin.
Yaoshania pachychilus, the panda loach, is a species of gastromyzontid loach endemic to mountain streams in Jinxiu County, Guangxi in China. This species grows to a length of 5.8 centimetres (2.3 in) SL. This species is monotypic, but it was formerly included in Protomyzon. Juveniles are strikingly coloured in black-and-white, but adults are relatively plain. Y. pachychilus has quickly become a popular aquarium fish in the 2010s.
The Gastromyzontidae are a family of loaches native to China and Southeast Asia, where typically found in streams and rivers with a fast current. The family includes about 137 species in eighteen genera. This family was resurrected by M. Kottelat in his review and revision of the loaches in 2012. They are commonly called hillstream loaches.
Troglonectes is a genus of troglobitic fish in the family Nemacheilidae, native to caves of Asia. Fishbase and other authorities place these species in the genus Oreonectes.
