; acqua dolce demersale. Tropical; 22°C - 28°C (Ref. 13614)
Africa: widespread in coastal basins from the Sanaga (Cameroon) southwards to the Chiloango (Cabinda province of Angola) (Ref. 74661, 81642). Also in the Congo River basin (Ref. 50834, 74661), from the lower Congo (Ref. 50834, 120641) to the upper Lualaba (Ref. 45616).
Dimensione / Peso / Età
Maturità: Lm ?  range ? - ? cm
Max length : 31.7 cm SL maschio/sesso non determinato; (Ref. 81642)
Spine dorsali (totale) : 2. Diagnosis: caudal peduncle relatively long, its depth a little larger than horizontal distance between the base of adipose and caudal fins (but almost never twice as great); pectoral spine smooth on its anterior margin, except for a few serrations near the tip; preorbital head length less than maximum head depth; color pattern on flank strongly marked in most cases; adipose fin height 3-7% SL, dorsal fin height 15-25% (28%) SL), head depth 56-88% head width; barbels relatively short, e.g. external mandibular barbel usually shorter than 1.3 times HL, never reaching beyond tip of pectoral spine (Ref. 81642).
Maximum recorded total length 39.0cm (Ref. 3236).
