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. Feeds mainly on aquatic insects and detritus. A surface feeder (Ref. 1479). Spawning sites are found in rivers and ponds (Ref. 33813). Mature adults probably breed during the rainy season. Hardy and adaptable in the aquarium.

营养阶层 (Ref.
69278): 3.1 ±0.1 se; based on diet studies.
Generation time: 1.0 ( na - na) years. Estimated as median ln(3)/K based on 2
growth studies.
