Classification / Names Common names | Synonyms | Catalog of Fishes (gen., sp.) | ITIS | CoL | WoRMS | Cloffa

Actinopterygii (ray-finned fishes) > Perciformes (Perch-likes) > Cichlidae (Cichlids) > Pseudocrenilabrinae
Etymology: Hemichromis: Greek, hemis = half + Greek, chromis = a fish, perhaps a perch (Ref. 45335).

Environment / Climate / Range Ecology

Freshwater; benthopelagic; pH range: ? - 7.0; dH range: ? - 15.   Tropical; 23°C - 25°C (Ref. 2060)

Distribution Countries | FAO areas | Ecosystems | Occurrences | Point map | Introductions | Faunafri

Africa: Cameroon to the Republic of Congo, the entire Congo River, Okavango and Zambesi system (Ref. 81260) and the Cuanza River (Ref. 11970). Also reported from west Africa (Guinea, Sierra Leone, Liberia, Togo, Benin, Nigeria) (Ref. 43352, 81260), but this needs confirmation (Ref. 53405). Upper Zambezi and (some) Congo populations may represent a different species (Ref. 81260).

Length at first maturity / Size / Weight / Age

Maturity: Lm 10.7, range 10 - 11.5 cm
Max length : 18.7 cm SL male/unsexed; (Ref. 81260)

Short description Morphology | Morphometrics

Dorsal spines (total): 13 - 15; Dorsal soft rays (total): 11-12; Anal spines: 3; Anal soft rays: 8 - 10. Diagnosis: 4-5 distinct blotches or ovoid bars along lateral mid-line (Ref. 44091, 81260), but bands not obvious in large males which assume a very dark to almost black coloration (Ref. 44091). Scales olive to yellow; series of thin red dots often forming horizontal lines along the mid-portion of flanks; normally 2 rows of teeth on upper jaw (Ref. 81260). Magenta spot on gill cover (Ref. 44091).

Biology     Glossary (e.g. epibenthic)

Found in shallow lakes and streams (Ref. 58302). Highly predaceous and thus used in some areas for tilapia control; feeds on fish, shrimp and aquatic insects; very aggressive and territorial (Ref. 44091); the parents guard the nest and larvae (Ref. 7248). Pair-bonding, substrate brooder (Ref. 81260). Oviparous (Ref. 205).
