Etymology: Chromidotilapia: Greek, chromis = a fish, perhaps a perch + Bechuana, African native thiape = fish (Ref. 45335).
Environment / Climate / Range
Freshwater; benthopelagic; pH range: 6.0 - 8.0; dH range: 5 - 19; potamodromous (Ref. 51243). Tropical; 23°C - 25°C (Ref. 1672); 12°N - 2°N
Length at first maturity / Size / Weight / Age
Maturity: Lm 6.0  range ? - ? cm
Max length : 14.5 cm SL male/unsexed; (Ref. 53405)
(total): 15 - 17;
soft rays: 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).
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.
Substrate spawning, ovophilic, pair bonding, male mouthbrooding species (Ref. 81260). Both parents take care of the young after hatching (Ref. 47115).
