Diagnosis: large, big-toothed brownish species; eyes rather large; premaxillary pedicel relatively short (Ref. 55949).
Common on the shelf zone; occasionally found off reefs; but not commonly recorded from the middle of the lake (Ref. 55949). Moves in the open water but stays 2-5 m above the substrate; feeds on fish like the small Utaka and Usipa (Engraulicypris sardella) (Ref. 5595).
Species probably forms breeding leks on or near the bottom; juveniles are common in the adult habitat (Ref. 55949).
