Short description
Bestämningsnycklar | Morfologi | Morfometri
Taggstrålar i ryggfenan (totalt) : 7 - 11; Mjukstrålar i ryggfenan (totalt) : 8 - 13; Taggstrålar i analfenan: 1; Mjukstrålar i analfenan: 7 - 11.
Length in freshwater is recorded at 6.5 cm TL; in the sea, it is recorded at 8.5-9.0 cm TL (Ref. 2058). Males build, guard and aerate the nest where the eggs are deposited (Ref. 205).
