This species is distinguished from related species in the Black Sea basin by the following characters: 75-95 % of distance between its origin and anus; ctenoid scales completely cover predorsal area and nape; pelvic disc fraenum with angular lobes, fraenum length 1/6-1/2 of its width at base; scales in midlateral series 68-72 + 3-4; snout length 1.5-2.0 times in eye diameter; first branched ray of second dorsal about as long as penultimate ray; posterior part of first dorsal without black spot (Ref. 59043).
Usually in freshwater and brackish water with very low salinity (< 2 ppt); in lower rivers and lagoons, lakes, large rivers, harbours on rocky or well-vegetated bottom (reed thickets) in still waters as well as rapids. Initial spawning at 2 years, in March to May, where adhesive eggs are deposited on stones, shells and aquatic plants; while males guard the eggs until hatching. (Ref. 59043). Feeds on crustaceans (mysids, corophiid amphipods) and small fish (gobies) (Ref. 4696).
