East Africa: Rovuma River system including Niassa Reserve, and western confluences to Lake Malawi (Ref. 91771). Following a recent revision of the Petrocephalus catostoma complex (Ref. 91771), unambiquous evidence for the presence of this species in the Bangweulu-Mweru area (and consequently the Congo basin) is still lacking (Ref. 91772).

Short description Morfología | Morfometría

Espinas dorsales (total): 0; Radios blandos dorsales (total): 18-22; Espinas anales 0; Radios blandos anales: 25 - 28.

Occurs in shallow and muddy waters, sheltered bays, in lagoons, and swampy areas; prefers quiet parts of rivers where there is abundant vegetation (Ref. 13337). Forms shoals (Ref. 13337) within quiet reaches of rivers and floodplains, and with other species with identical electric organ discharge (EOD) waveforms (Ref. 10460). Feeds on insects, found on river bed or in marginal vegetation (Ref. 12526), on insect larvae and other invertebrates at night (Ref. 5595). Known to undergo upriver migration (Ref. 13337, 10608) which may well be correlated with breeding (Ref. 13337). Breeds during the rainy season, possibly moving upstream to suitable sites (Ref. 10608). An unconfirmed report claims the males are territorial and build a nest (Ref. 7248). Caught in nets for food (5214). Oviparous (Ref. 205).
