Ecologie
marien; zoet water; brak water demersaal; amfidroom (Ref. 46888); diepte 0 - 2 m (Ref. 12215). Temperate; 47°N - 38°N, 12°E - 61°E

Lengte bij maturiteit / Grootte / Gewicht / Leeftijd
Maturity: Lm 2.2, range 2 - 2.3 cm
Max length : 5.0 cm TL mannelijk / geslacht onbekend; (Ref. 4696); max. gerapporteerde leeftijd: 2.00 Jaren (Ref. 126411)
Dorsale stekels (totaal): 7; Dorsale zachte stralen (totaal): 7-8; Anale stekels 1; Anale zachte stralen: 7 - 9; Wervels: 31 - 32. 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.
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).
