Africa: central Congo River basin in the western Cuvette Centrale and central Cuvette Centrale, including the rivers Alima, Lefini, lower Sangha, Ruki and Maringa (Ref. 55074, 74387, 92878), in Democratic Republic of the Congo and Republic of Congo.

Short description
Morfologi | Morfometri
Taggstrålar i ryggfenan (totalt): 16 - 17; Mjukstrålar i ryggfenan (totalt): 9-11; Taggstrålar i analfenan 3; Mjukstrålar i analfenan: 8 - 9. Diagnosis: differs from C. crassa and C. louna by having 1 complete scale row and 1 additional scale row with smaller dorso-ventrally compressed scales between upper lateral line and base of last dorsal spine (vs. 2 complete scale rows and 1 additional row of very small scales in-between); differs from C. crassa by a shallower body with only a minimal overlap, 32.2-40.5% SL vs. 40.4-48.4%; and from C. louna by a shorter last dorsal spine, 9.4-12.2% SL vs. 12.9-15.0%; all scales cycloid; 26-27 scales on horizontal line; 17-22 upper lateral line scales; 8-11 lower lateral line scales (Ref. 92878).
Found in swampy forested zones (Ref. 52307) in grass-bank as well as forest-bank habitats, during the dry as well as the wet season (Ref. 92878). Pair-bonding, open substratum spawner with both parents guarding their fry (Ref. 52307).
