Africa: coastal basins from the river St. John in Liberia to lower Cameroon and the Benito River in Equatorial Guinea, in forest and northern adjoining savannah; also known from the Niger and the Bénoué River (Ref. 53405). Previously, two subspecies were recognized: Chromidotilapia guntheri guntheri and Chromidotilapia guntheri loennbergi.

Description synthétique Morphologie | Morphométrie

Épines dorsales (Total): 15 - 17; Rayons mous dorsaux (Total): 9-12; Épines anales 3-4; Rayons mous anaux: 6 - 8. Diagnosis: 21-25 rakers on first gill arch; when stressed with two continuous dark bands on body; 1st dorsal fin spine 30-35% length of fifth spine; caudal fin truncate to subtruncate; dorsal head profile straight; iris yellow to brownish, posterior half sometimes red; upper lip white or pale blue; anterior 2-3 dorsal fin spines with black interspinous membrane in juveniles (Ref. 81260).

Biologie     Glossaire (ex. epibenthic)

Substrate spawning, ovophilic, pair bonding, male mouthbrooding species (Ref. 81260). Both parents take care of the young after hatching (Ref. 47115).

Life cycle and mating behavior Maturité | Reproduction | Frai | Œufs | Fécondité | Larves

Male mouthbrooder; both parents take care of the young after hatching (Ref. 47115). This corrects previous information from Ref. 26489.
