Short description
Morfologi | Morfometri
Taggstrålar i ryggfenan (totalt): 1 - 3; Mjukstrålar i ryggfenan (totalt): 8-13; Taggstrålar i analfenan 1-3; Mjukstrålar i analfenan: 5 - 8. Transverse scale rows: 10-13. Distinguished from all other family members by having 3 or less dorsal spines (versus 7 or more), 6-7 broad dark bars along flanks (versus 7 or more), 16-18 peduncle scale rows (versus 18-24).
Found on sand, clay, mud and/or limestone substrate commonly associated with rooted, submerged vegetation (Ref. 58011). Oviparous, eggs are deposited in aquatic vegetation, preferably on strands of Ceratophyllum sp. when available (Ref. 58020).
