Short description Claves de identificación | Morfología | Morfometría

Diagnosis: 2 scale rows between lateral line and scaly process at pelvic-fin bases; eye <70% of interorbital space (Ref. 2880, 81279). Dorsal-fin uniformly greyish and its origin in front of pelvic fins; adipose fin greyish; caudal fin without black edge (Ref. 80290, 81279).

Forms shoals; an open water predator often found near the water surface; feeds on fishes, preferring long bodied fish as they are easier to swallow and also takes insects, grass and snails; cannibalistic; preyed upon by fish eagle Haliaeetus vocifer; breeding migrations have been reported up several tributaries of Lake Kariba during the rains (Ref. 13337).
