Schistura athos is a species of ray-finned fish in the stone loach genus Schistura, its specific name athos is from, Athos, one of the Three Musketeers by Alexandre Dumas, as do that of two other Schistura species endemic to the Nam Ou basin, S. aramis and S.porthos. It has only been recorded from the Nam Ou basin in Laos, as well as from a stretch of the Nam Noua, a tributary of the Nam Ou, in Vietnam. S. athos has been collected from rapids and stretches of the main river with stone substrates.
Schistura carbonaria is a species of ray-finned fish in the stone loach genus Schistura. It is found in central Vietnam in some coastal drainage systems, from the Ve River to the Qang Tri River, and the River Xe Kong, in the Xe Kong its range may extend into Laos.

Schistura khamtanhi is a species of ray-finned fish in the genus most speciose genus in the stone loach family, Schistura. It is found in the Kong River basin in Laos and in the main Mekong river in Cambodia and Laos where it is abundant, being an important quarry species for the fish traps at Kohne Falls. It inhabits rapids and Sony bottomed stretches of the main Mekong and its tributaries and it migrates past the Kohne Falls in January and February annually. It is the only member of the genus Schistura which is known to be migratory. The specific name honours Khamtanh Vatthanatham, a Fisheries Programme Officer of the Mekong River Commission who was very helpful to the Maurice Kottelat during his 1999 survey, in which this species was discovered.
Schistura khugae is a species of ray-finned fish in the stone loach genus Schistura. It lives on the bottom of hill streams in the Khuga River, part of the Chindwin River system in Manipur, India.
Schistura kontumensis is a species of ray-finned fish, a stone loach, in the genus Schistura. It has only been recorded a few times from large rivers and streams in the headwaters of the Sesan River which is a tributary of the Sekong River, which is a tributary of the Mekong, in Kontum Province, Vietnam. When sampled., however, it was found to be common and hardy, tolerating water which had flown through urban areas and which had been polluted with water used for washing. Iys population trends are unknown and despite its hardiness it may have been affected by dams.
Schistura leukensis is a species of ray-finned fish, a stone loach in the genus Schistura. It has only been recorded from a single river, a tributary of the Mekong in Laos. This river has been affected by damming upstream of this species' main habitat and it is unknown how this has impacted the population. Other human activities such as deforestation, agriculture, siltation and pollution may have also had effects on this species.
Schistura macrocephalus is a species of ray-finned fish. a stone loach, in the genus Schistura. It occurs in riffles over stony or gravel beds in streams with moderate to fast currents in the Mengla River in Yunnan, a tributary of the Mekong, and the Nam Youan in northern Laos, in turn a tributary of the Mengla.
Schistura macrotaenia is a species of ray-finned fish, a stone loach, in the genus Schistura. It occurs in the Tengtiao Jiang River drainage in Yunnan and may also occur in the same river drainage in northern Vietnam.
Schistura minuta is a species of ray-finned fish, a stone loach, in the genus Schistura, a benthic species found in hill streams in the Iyei River drainage in Manipur, India.
Schistura nagaensis is a species of ray-finned fish, a stone loach, in the genus Schistura. It is a benthic species which is found in hill streams with a fast currents over a gravel substrate. It occurs in the Tizu River in the Chindwin basin of Manipur and Nagaland, it may also occur in the Tizu River in Myanmar. Slash and burn cultivation within the drainage of the Tizu has contributed to a decline in quality of hill stream habitats and resultant threats to fish populations which are also threatened by destructive fishing techniques including the use of explosives and poisons.
Schistura namboensis is a species of ray-finned fish, a stone loach, in the genus Schistura. It normally occurs in the rapids and riffles of medium-sized rivers and streams but it can also be found in reaches with a slow current and sandy substrate. This species appears to have some resistance to organic pollution and occurs in streams flowing through settlements, and is often the last fish species to remain in such streams. It is found in the coastal drainages in southern and central Vietnam and also in Laos in some rivers which rise there before flowing into Vietnam.
Schistura pertica is a species of ray-finned fish, a stone loach, in the genus Schistura. It has only been recorded once, in 1997, from a very small stream entering the Nam Ou River, downstream of the Muang Khoa River in northern Laos, it is expected to occur elsewhere in the Nam Ou drainage. It was observed in streams with a moderate to fast current, in riffles, over beds varying from gravel to stone
Schistura sexcauda is a species of ray-finned fish, a stone loach, in the genus Schistura. It is found in the basin of the Chao Phraya River in central Thailand where it has been recorded in streams with a moderate to fast current and in riffles, over substrates consisting of gravel to stone. It is known to be raised in local subsistence fisheries and traded both nationally and internationally as an ornamental fish.
Schistura waltoni is a species of ray-finned fish, a stone loach, in the genus Schistura. It is a species of in streams which have a moderate to fast current where it can be found in riffles, over gravel to rock beds. It is often recorded in small streams in forest, even where the water is very shallow. It occurs in the upper reaches the Chao Phraya watershed in Thailand in the rivers Mae Nam Ping, Mae Nam Wang and Mae Nam Yom. The specific name honours Joseph Walton a 19th Century contributor to the fish collection at the Academy of Natural Sciences of Philadelphia.
