Occurs from the lower reaches of rivers to the deepest habitable parts of the lake (Ref. 4967). Inhabits a variety of habitats (Ref. 52142). Feeds on small demersal cichlids (Ref. 52142) during the night (Ref. 5595). Juveniles mainly feed on trophic eggs released by the female (Ref. 36945), whilst the male helps the young in searching for invertebrates in and around the nest (Ref. 36945). Mutualistic relationship with cichlids concerning defense and feeding of young of both the cichlid and B. meridionalis (Ref. 52146). Symbiotic relationship of parasitized host-parasite eater exist with Pseudotropheus crabro, which eats away necrotic tissue and parasites, but also steals eggs (Ref. 42778). Oviparous (Ref. 205). Can produce sound as Amia or Synodontis species (Ref. 42447). Considered as a delicacy when smoked, making it one of the most highly priced fishes of Malawi (Ref. 52150).

Oviparous. Breeding sites may be found in rivers, lakes, ponds or swamps (Ref. 205). Breeding individuals are recorded at all depths, but the species appears to prefer shallow water (<50m) (Ref. 4916, 27004, 52142). It comes inshore to breed, a nest being made in shallow water on a sandy substrate (Ref. 4364). Nest are build by males, with a circular or oval shape, about 3 feet in diameter, the centre below the surface level (Ref. 4916). Reputed to breed among the rocks (Ref. 2781, 52146), with nest often build so that rocks provide extra cover (Ref. 4916). Small fish are being guarded in their nests (Ref. 52142). The female exhibits parental care of her brood of young, in co-operation with nest-guarding territorial cichlids (Ref. 27004). In other studies, parental care is exhibited by both male and female (Ref. 52178, 52179). Brood-mixing occurs when cichlid parents 'farm out' their young into broods of the catfish and in half the cases, the cichlid parents remain near by and assist in brood defence (Ref. 52143). Juveniles mainly feed on trophic eggs released by the female (Ref. 36945), whilst the male helps the young in searching for invertebrates in and around the nest (Ref. 36945). Mutualistic relationship with cichlids concerning defence and feeding of the young of both the cichlids and B. meridionalis (Ref. 52146). If the female, after laying the eggs, leaves the nest in charge of the male (which is generally smaller than the female) and goes back to deep water, this might account for the disparity in sex ratio observed between shallow and deep waters (Ref. 4364, 4916).
