Inshore habitats, estuaries, brackish- and fresh-water lagoons and lakes, large rivers, harbours, on sand or rock bottom. To 50-60 m deep in Black Sea during winter. Mostly found on well vegetated or rock bottom.
Lives up to four years. Males reproduce for the first time at 3-4, females at 2-3. Spawns in April-September. Males have entirely black body during spawning season. Individual females may repeat spawning during a season every 18-20 days. Adhesive eggs are deposited under or between stones, shells and aquatic plants. Males guard eggs until eggs hatch, in 2-3 weeks. Males usually die after spawning season. Feeds on a wide variety of invertebrates and small fish. Egg clutches are supposed to be occasionally transported attached to the hull of ships, facilitating the invasion of new areas.
