Homalopterula is a genus of hillstream loaches found only in Sumatra in Indonesia.
There are currently 6 recognized species in this genus: [1]
Cypriniformes is an order of ray-finned fish, including the carps, minnows, loaches, and relatives. This order contains 11-12, although some authorities have designated as many as 23, families 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.
Beaufortia kweichowensis is a species of gastromyzontid loach native to rivers in China. The common names for this popular aquarium species are Chinese hillstream loach, Hong Kong pleco, butterfly hillstream loach, and Chinese sucker fish.
Lepidocephalichthys is a genus of ray-finned fish in the family Cobitidae.
Neolissochilus is a genus of fish in the family Cyprinidae native to freshwater habitats in Asia that are often grouped with the mahseers. The largest reach up to 1.2 m (3.9 ft) in length, but most species are much smaller.
Poropuntius is a genus of cyprinid fish found mainly in freshwater habitats of Southeast Asia and Yunnan in China, but P. burtoni is from South Asia. Several species have highly restricted ranges and are threatened, and a single P. speleops is a cavefish.
