Asia: Mekong, Chao Phraya and Salween basins, northern Malay Peninsula, westwards to the Indus and Sri Lanka.
Occurs in a variety of habitats (Ref. 27732): ditches, ponds, canals, haors, streams, rivers and inundated fields (Ref. 1479). Inhabits mainly sandy streams and rivers (Ref. 6028). Found in medium to large rivers and brooks of the middle Mekong (Ref. 12975). In the Mekong basin, this species is usually associated with large, slow flowing rivers, usually with turbid waters (Ref. 43281). Sometimes forms large schools.
