In rivers it is kept away from strong currents, prefers backwaters, backwaters with aquatic vegetation. However, she tries to avoid dense vegetation. In the lakes in most cases it lives in the shallows where the water warms up more. Wetlands and mudflats ponds roach escapes, which are often observed Zamora, and the mountain river she escapes.
Eating the roach is the vegetation, although she is not squeamish and animal food. For example, before the construction of the Kremenchug reservoir, located on the middle reaches of the Dnieper, roach fed on higher aquatic plants, their seeds and filamentous algae.
