It lives for a year and matures at 18-20 mm SL. Spawns after first winter, May-June, down to 2-7 m, with females probably laying 2-3 portions of eggs (0.4-1.0 mm), separately attached inside a mollusc shell; and adults dying soon after spawning. Feeds on small crustaceans (Ref. 59043). Reshetnikov, Y.S., N.G. Bogutskaya, E.D. Vasil'eva, E.A. Dorofeeva, A.M. Naseka, O.A. Popova, K.A. Savvaitova, V.G. Sideleva and L.I.
