Taggstrålar i ryggfenan (totalt) : 7; Mjukstrålar i ryggfenan (totalt) : 14 - 15; Taggstrålar i analfenan: 2; Mjukstrålar i analfenan: 44 - 47.
Body shape (shape guide): short and / or deep.
Adults inhabit mangrove-nipa swamps, brackish estuaries and slow-flowing turbid rivers. Feed on small fishes, shrimps and crayfish. The male carries the eggs around like a bunch of grapes attached to a hook on the head, called forehead brooding (Ref. 36739, 44894). Esteemed table fish (Ref. 2158).
