Ecology: This is a demersal species found in lakes , swamps and rivers in water less than 12 m deep. Preys on small fish, but also on insects, crustacea, molluscs , vegetable matter and detritus . It spends nearly the whole of the daylight hours in crevices of rocks and is therefore seldom seen. Lives and feeds on or near the bottom . Adults are piscivorous , particularly Alestes spp, and also feed on insects, crustaceans, molluscs and vegetable matter. There is some indication that the species comes to shallower water to breed . Spawning season extends from April to July. Parents build and guard the nest , which is like a flat disc with a central hole where the eggs area. Males live up to 7 years old, females 8 years. Reputed to reach 100,000 g. (Ref. 256725).
