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).
非洲: 幾內亞到安哥拉。

簡短描述 型態特徵 | 形態測量圖

背棘 (總數): 13 - 16; 背的軟條 (總數): 11-13; 臀棘 3; 臀鰭軟條: 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).
在鰓蓋上的一個紅紫色斑點提供最好的鑑別特徵; 身體橄欖綠色的有五個深色的垂直條紋, 但是條紋不是明顯的在大雄性中那一個呈現一非常深色的對幾乎黑色的顏色.(參考文獻 44091)

生物學特性     字彙 (例如 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).

高度食肉而且對於吳郭魚控制如此被用於一些區域; 吃魚,蝦與水生昆蟲; 非常有侵略性與具有領域性;(參考文獻 44091) 父母保衛巢與仔魚。 (參考文獻 7248) 卵生的.(參考文獻 205)
