Korte beschrijving
Morfologie | Morfometrie
Dorsale stekels (totaal): 0; Dorsale zachte stralen (totaal): 39-45; Anale stekels 0; Anale zachte stralen: 26 - 32. Diagnosis: body elongate; lateral-line scales medium-sized, numbering 65-78; head depressed anteriorly, relatively long and covered with scales larger than those on body; lower jaw slightly longer than the upper, with 4-6 well developed canines; dorsal and anal fins not touching caudal fin; dorsal fin with 39-45, anal with 26-32 rays; 5-8 more or less rounded or polygonal dark blotches on sides (Ref. 57290, 81648).
Coloration: blackish to very dark olivaceous, marbled with ochre ventrally; dark lateral band on head, broadening between hind margin of eye and hind margin of gill cover; fins with more or less distinct dark spots/maculae forming oblique bands; small, rounded black spot at base of caudal fin; fingerlings (prejuveniles) ochre-coloured, with a black band running along middle of sides, from tip of snout to hind margin of caudal fin (Ref. 57290, 81648).
Inhabits marginal vegetation and floodplains. Feeds on insects and small fish (Ref. 28714). Maximum SL reported 50.0 cm (Ref. 31256) larger than maximum TL 45.5 cm (Ref. 81648).
