Rasboras (Cyprinidae)
Rasboras are freshwater fishes belonging to the Cyprinidae family. They are distributed throughout South and Southeast Asia, with the greatest diversity occurring in the Malay Peninsula, Borneo, Sumatra and surrounding regions. Rasboras are distinguished by their slender, laterally compressed body, small terminal mouth, toothless jaws, pharyngeal teeth located in the throat, and the absence of barbels in most species.
Rasboras inhabit rivers, streams, forest creeks, peat swamps, lakes and floodplains. Most species are active schooling fishes that feed on aquatic insects, insect larvae, small crustaceans, worms and other tiny aquatic invertebrates.
Cyprinidae is the world's largest family of freshwater fishes, containing approximately 361 genera and about 2,900 recognised species, including carps, minnows, barbs, danios, mahseers and goldfish. Approximately 170 cyprinid species have been recorded in Malaysian waters. This page highlights several commonly encountered rasbora species.
