Biology

Adults occur mainly in quiet waters, lakes and pools (Ref. 248) and prefer rather shallow and swampy areas with a soft muddy substrate and calmer water (Ref. 78218). They may also occur in fast flowing rivers and in rapids (Ref. 248, 78218). Widely tolerant of extreme environmental conditions (Ref. 6465). Water parameters appear to play only a very minor role (Ref. 78218). The presence of an accessory breathing organ enables this species to breath air when very active or under very dry conditions. They remain in the muddy substrates of ponds and occasionally gulp air through the mouth (Ref. 6465). Can leave the water at night using its strong pectoral fins and spines in search of land-based food or can move into the breeding areas through very shallow pathways (Ref. 6868). Are omnivorous bottom feeders which occasionally feed at the surface (Ref. 248). Feed at night on a wide variety of prey (Ref. 6868) like insects, plankton, invertebrates and fish but also take in young birds, rotting flesh and plants (Ref. 6465). Migrate to rivers and temporary streams to spawn (Ref. 34291). Also caught with dragnets. During intra-specific aggressive interactions, this species was noted to generate electric organ discharges that were monophasic, head-positive and lasting from 5-260 ms (Ref. 10479). Known as sharptooth catfish in aquaculture, a highly recommended food fish in Africa (Ref. 52863). Marketed fresh and frozen; eaten broiled, fried and baked (Ref. 9987).
