Africa: widely distributed in the coastal rivers of Lower Guinea, from the Ntem in Cameroon to Kouilou basin in Republic of Congo, including the Woleu, Ogowe and Nyanga rivers (Ref. 81260, 123791). Also in the Dja River, an affluent of the Middle Congo basin (Ref. 123791). Populations from entire Congo River basin and southern African basins, including Okavango, Zambesi and Cuanza (Ref. 11970, 120641), are also considered as conspecific (Ref. 123791), and may represent a distinct species (Ref. 81260). Also reported from West Africa in Guinea, Sierra Leone, Liberia, Togo, Benin and Nigeria (Ref. 43352, 81260), but this needs confirmation (Ref. 53405).

背棘 (总数): 13 - 16; 背的软条 (总数): 11-13; 臀棘 3; 臀鳍软条: 7 - 10. Diagnosis: Hemichromis elongatus can be distinguished from H. camerounensis by the presence of a single red opercular spot or a mixture of reddish and yellowish spots dorsally of the large black opercular spot instead of two red opercular spots on the both sides of the black spot in H. camerounensis (Ref. 123791). It can be distinguished from H. fasciatus by the absence of small black dots between the first three dark stripes on the sides of the body of adults (Ref. 123791). With 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).
在鳃盖上的一个红紫色斑点提供最好的鉴别特徵; 身体橄榄绿色的有五个深色的垂直条纹, 但是条纹不是明显的在大雄性中那一个呈现一非常深色的对几乎黑色的颜色.(参考文献 44091)

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).
