Short description
Claves de identificación | Morfología | Morfometría
Radios blandos dorsales (total) : 9; Radios blandos anales: 7. Black stripe from eye to caudal fin; nearly complete lateral line, with only last few scales lacking pores (Ref. 12693).
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.
