Africa: widely distributed in West Africa, where it is known from most hydrographic basins (Ref. 53405). Also in the Nile basin, Lake Chad basin and in the upper Zambezi (Ref. 5644). Distribution of this species and overlap with Hemichromis elongatus unclear, but probably absent from the Congo basin (see also Ref. 43352, 52307, 53405, 81260). Introduced around 1970 in a stream fed by hot springs in Villach (Austria) (Ref. 59043).

Kurzbeschreibung Morphologie | Morphometrie

Rückenflossenstacheln (insgesamt): 14 - 15; Rückenflossenweichstrahlen (insgesamt): 11-13; Afterflossenstacheln 3; Afterflossenweichstrahlen: 8 - 11. Diagnosis: 5 dark blotches or cross bars on sides, often alternating with narrower intercalary bars, the first blotch confluent with the opercular spot, the fifth on caudal-fin base; upper profile of snout straight or concave (Ref. 53405).

Biologie     Fachlexikon (Englisch) (z.B. epibenthic)

Occurs in both forest and savannah biotopes (Ref. 5644); present in littoral riverine habitats and permanent floodplain lagoons with clear water. Feeds on shrimps, small fishes (Ref. 52307) and insects. A nesting substrate spawner which breeds in the early summer. Pair-bonding well defined (Ref. 52307). Used for tilapia control (Ref. 4537). Maximum TL was recorded at 26.5 cm.

Life cycle and mating behavior Geschlechtsreife | Fortpflanzung | Ablaichen | Eier | Fecundity | Larven

Introduced individuals in Austria reported to form pairs during spawning. Female deposits eggs on exposed hard surfaces such as stones or wood. Both parents guard larvae and juveniles for 4-8 weeks (Ref. 59043).
