Triplophysa 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 (Hedinichthys Indotriplophysa Labiatophysa Qinghaichthys Tarimichthys Kottelat and the Catalog of Fishes are treated as genera in Wikipedia . FishBase , however, includes these in Triplophysa .
Triplophysa zhaoi holds the record for the lowest altitude for Asian fish: it is found at 50 m (160 ft) below sea level in swamps of the Lükqün oasis, in the Turpan Depression in Xinjiang . In the other end, Triplophysa stolickai holds the record altitude for Asian fish: it is found at 5,200 m (17,100 ft) above sea level in hot springs near the Longmu Lake in western Tibet. Triplophysa dalaica has been used as model species to study adaptation to high-altitude hypoxia and 13 positively selected genes involved in hypoxia response have been identified. Some species are blind cave-dwellers .
