Anterior oculoscapular, preopercular, and sometimes posterior oculoscapular, canals present; body squamation complete on caudal peduncle and along at least lateral midline to axil. Males with 4-5 major vertical bars.
Body shape (shape guide): elongated.
Inhabit fresh to hyper-saline waters (to 55 ppt) of lakes, estuaries and lagoons, in shallow areas with much weed. Feed on small crustaceans and chironomid larvae (Ref.12215); larvae of the mussel Dreissena polymorpha (Ref. 59043). Lives less than 2 years. Spawns after first winter. Eggs are attached to the roof of a cavity under stones, plant material or shells and are defended by male. Postlarvae are pelagic. (Ref.59043).
Spawns up to 4 portions of eggs (Ref. 59043).
