Etymology: Hemichromis: Greek, hemis = half + Greek, chromis = a fish, perhaps a perch (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Freshwater; benthopelagic. Tropical; 22°C - 26°C (Ref. 2059)
Africa: Equatorial Guinea to Cabinda, including central regions of Gabon (Ref. 81260). Also in western Republic of Congo (Ref. 81260) and in the Congo River from Pool Malebo (=Stanley Pool) to its estuary (Ref. 43352). Also present in the Likouala and Likouala-aux-Herbes, upstream from Pool Malebo in the middle Congo River basin, in Republic of Congo (Ref. 43352).
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 10.0 cm SL male/unsexed; (Ref. 5644)
(total): 13 - 15;
soft rays: 7 - 9. Diagnosis: never with multiple series of distinct blotches or bars on flanks; iridophores often visible on head, but rarely present on body or unpaired fins; mid-lateral black spot always present, rounded and relatively large, sometimes bordered by a light zone around posterior and anterior edges (but not fully ocellated); sometimes small black spots and/or 7-9 narrow black bars on dorsum, sometimes reaching to mid-body; black spot on caudal peduncle normally absent, or if present, small and ovoid (Ref. 81260).
Pair-bonding, substrate brooder (Ref. 52307, 81260).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01445 (0.00674 - 0.03099), b=2.97 (2.80 - 3.14), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.3 ±0.5 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (14 of 100) .
