Balitoridae, the hillstream loaches or river loaches, is a family, 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.
The Khone Falls and Pha Pheng Falls together form a waterfall located in Champasak Province on the Mekong River in southern Laos, near the border with Cambodia. It is the widest waterfall in the world at 10,783 metres in width from one edge of its multiple channels to the other.

Hemimyzon taitungensis is a species of ray-finned fish in the family Balitoridae that is endemic to Taiwan. It is a small freshwater fish currently known only from running waters of the Central Mountain Range of Taiwan at high and middle elevations. In contrast to H. formosanus, it appears to be a well-defined species with no signs of strong genetic structuring suggestive of cryptic species.
Hemimyzon is a genus of freshwater ray-finned fish belonging to the family Balitoridae, the river or hillstream loaches. The species in this genus are found in eastern Asia.
Hemimyzon confluens is a species of ray-finned fish in the genus Hemimyzon. It is known from a single location in the Nam Ngum drainage in Laos, a tributary of the Mekong. The known material suggests a maximum standard length of about 47 mm (1.9 in). H. confluens is threatened by pollution from mining activities and hydro-power development.
Hemimyzon ecdyonuroides is a species of hillstream loach in the genus Hemimyzon. It is known from two tributaries of the Mekong, from Sekong River and Sesan River drainages in Vietnam and Laos.
Hemimyzon formosanus is a species of hillstream loach in the genus Hemimyzon. It is endemic to western portion of Central Mountain Range of Taiwan. Its maximum length is 10 cm (3.9 in). Variations in nucleotide sequences within the mitochondrial control region show strong geographic structuring suggestive of a cryptic species complex.
Hemimyzon khonensis is a species of hillstream loach in the genus Hemimyzon. It is known from a single specimen collected in the Mekong at the Khone Falls in Laos, near the Cambodian border; it is named for the falls. The specimen was 51 mm (2.0 in) in standard length.
Hemimyzon macroptera is a species of hillstream loach in the genus Hemimyzon. It is found in clear-water streams with rocky bottom in the Nanpan River basin, Yunnan, China. It is naturally scarce but widespread.
Hemimyzon megalopseos is a species of ray-finned fish in the genus Hemimyzon.
Hemimyzon nanensis is a species of hillstream loach in the genus Hemimyzon. It occurs in the Chao Phraya basin, Thailand.
Hemimyzon nujiangensis is a species of hillstream loach endemic to Yunnan, China.
Hemimyzon pumilicorpora is a species of ray-finned fish in the genus Hemimyzon. it is a fresh water fish found in China. Males can reach up to 5.7 cm in length.
Hemimyzon papilio is a species of ray-finned fish in the genus Hemimyzon.
Hemimyzon sheni is a species of ray-finned fish in the genus Hemimyzon. It is only known from Tar-Ju River basin, Taitung County, southeast Taiwan, where its type locality is. Only three specimens were collected and later attempts to find more specimens have failed. Among its relatives, H. sheni most closely resembles H. formosanus, but it seems to be more a head-water species than H. formosanus. It is a small species with standard length of 5 cm (2.0 in).
Hemimyzon yaotanensis is a species of ray-finned fish in the genus Hemimyzon.
Hemimyzon elongata is a species of ray-finned fish in the genus Hemimyzon. It has been found in the Mekong basin in Yunnan, China. It is a benthopelagic, freshwater fish.

Hemimyzon yushanensis is a species of ray-finned fish in the genus Hemimyzon.
