Short description Bestämningsnycklar | Morfologi | Morfometri

Taggstrålar i ryggfenan (totalt) : 2; Mjukstrålar i ryggfenan (totalt) : 7; Mjukstrålar i analfenan: 12 - 13; Ryggkotor: 51 - 54. Distinguished from its congeners by a unique combination of the following characters: length of dorsal-fin base 13.7-16.7% SL, dorsal to adipose distance 8.6-14.2% SL, interorbital distance 28.4-31.8% HL, eye diameter 9.2-11.3% HL and a rounded snout (Ref. 41209).

Occurs in deeper rocky areas and tree roots (Ref. 37771). Species caught throughout the year. Enters flooded forest during the months of high water (July-October). Feeds on fish, shrimps and crabs (Ref. 9497).
