Inhabits a variety of slow-flowing or still waters from estuarine to small, slow flowing premontane streams; usually in dense vegetation or coarse rocks, and often very abundant in backwaters and lakes, breeds in reservoirs and channels. Preys on benthic invertebrates. Spawns for the first time at 1-2 years, usually for 1-2 seasons only, in April to August. Females may spawn more than once during the season and males guard the eggs that are deposited in cavities. Larvae and juveniles are benthic. It is invasive in Danube and Rhine where reportedly, the spreading was due to canalization of main river and reservoirs or slow-flowing waters created by hydroelectric plants (Ref. 59043).
