Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 7; Dorsal soft rays (total): 8; Anal spines: 1; Anal soft rays: 8. 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).

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).

Life cycle and mating behavior Maturities | Reproduction | Spawnings | Egg(s) | Fecundities | Larvae

Spawns eggs on submerged plants with small leaves. Female tends and fans the eggs until hatching and loosely guards the fry for a few days thereafter.
