Mainly nutrient-rich, well vegetated lowland rivers, backwaters, oxbows, ponds and lakes. Spawns on roots or submerged plants.

Biology:
Lives up to 17 years. Spawns for the first time at 3-4 years. Fractional spawner. Spawns in April-July, when temperature rises above 15°C. Males assemble at spawning grounds and drive ripe females, often with much splashing, into dense vegetation to spawn. Eggs are very sticky. Feeds predominantly on plankton, terrestrial insects and plant material. Able to adapt to unfavourable environmental conditions by slow growth and small size at maturity (stunted populations).
