|Scientific Name:||Hemichromis elongatus (Guichenot, 1861)|
Chromichthys elongatus Guichenot, 1861
Hemichromis auritus Gill, 1862
|Taxonomic Notes:||Loiselle (1979) comments on the presence of dwarfed populations of an “elongatus-like” fish in Lakes Barombi Kotto and Mboandong, Cameroon and these may represent a distinct species. With the availability of live specimens from the Congo basin and Upper Zambezi there are indications that these populations may also represent distinct species (Stiassny et al., 2007).|

|Population:||This species is widespread but fairly uncommon, e.g. only a single specimen was caught in a survey of the Okavango Delta (Tweddle et al. 2003).|
|Current Population Trend:||Unknown|
|Habitat and Ecology:||Hemichromis elongatus is a benthopelagic species. It is highly predaceous and thus used in some areas for tilapia control. It feeds on fish, shrimp and aquatic insects and is very aggressive and territorial (Yamamoto and Tagawa 2000). The parents guard the nest and larvae (Skelton 2001). This species is oviparous (Breder and Rosen 1966). It is closely associated with aquatic and emergent vegetation in the main rivers and large lagoons, also occurring in pools left by floodwaters (Tweddle et al. 2004). A nesting substrate spawner, breeding in early summer.|
|Use and Trade:||This species is harvested for human consumption.|
|Major Threat(s):||The species has a widespread distribution in large rivers and thus there are no major threats.|
|Conservation Actions:||The species has some protection in reserves.|
