Distribution Countries | FAO areas | Ecosystems | Occurrences | Point map | Introductions | Faunafri

Africa: from the middle Congo River basin (Kasai drainage and between the Lomami and Kisangani) up to the upper Lualaba and the Bangweulu area (Ref. 55074). Also in Lake Malawi, Zambesi, coastal areas from Zambesi Delta to Natal, Okavango and Cunene (Ref. 5163) as well as the Limpopo, Malagarasi (Ref. 55074) and Lake Tanganyika (Ref. 55074, 74387). Also present in the Cuanza and Catumbela rivers in Angola (Ref. 11970). Introduced elsewhere usually for weed control and aquaculture. Several countries report adverse ecological impact after introduction.

Length at first maturity / Size / Weight / Age

Maturity: Lm 17.7  range ? - ? cm
Max length : 45.0 cm TL male/unsexed; (Ref. 26550); max. published weight: 2.5 kg (Ref. 26550); max. reported age: 7 years (Ref. 7248)

Short description Morphology | Morphometrics

Dorsal spines (total): 15 - 17; Dorsal soft rays (total): 10-13; Anal spines: 3; Anal soft rays: 9 - 10; Vertebrae: 29. Head and body mid to dark olive-green dorsally, paling over the flanks. Body usually with vertical bars only and scales with a dark basal crescent. Dorsal fin olive-green with a thin red margin and white to grey dark oblique spots on the soft rays; caudal fin spotted on dorsal half and red or yellow on ventral half (Ref. 4967, 34290).

Biology     Glossary (e.g. epibenthic)

Prefer quiet, well-vegetated water along river littorals or backwaters, floodplains and swamps. Tolerant of a wide range of temperature (8-41°C) (Ref. 3) and salinity to 19 ppt (Ref. 7248). Form schools; is mainly diurnal. Juveniles feed on plankton. Adults feed mainly on higher plants and also algae, insects and crustaceans. Make excellent eating (Ref. 5214).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Prefers a sloping spawning ground near the marginal fringe of vegetation (Ref. 3). Builds nest in shallow water where both parents guard the eggs and young.
