Occurs in well vegetated lowland rivers, backwaters, oxbows, ponds, and lakes. Feeds mainly on macrophytes and terrestrial insects. Spawns on submerged plants when temperature rises above 18° C. May form locally hybrid populations with introduced Scardinius erythrophthalmus. Attains a maximum size of up to about 40 cm SL (Ref. 59043).
