Diagnosis: Longitudinal line scales 57-68; preopercular spine present; 8-10 gillrakers on lower part of first branchial arch (Ref. 5493, 79840). Dark brown to black in color; horizontal lines on body; young with spotted fins (Ref. 5493).
Body shape (shape guide): elongated.
Adults inhabit lagoons, estuaries and freshwater (Ref. 6028, 48637, 79840). They occur in the lower reaches of freshwater streams, usually on mud bottoms (Ref. 44894). Juveniles are found mainly among mangrove roots in the more saline areas of lagoons and estuaries (Ref. 6028, 79840). Carnivorous (Ref. 79840). Marketed fresh (Ref. 12693).
