Description

Haplochromis nubilus is a cichlid of East Africa, best known from Lake Victoria. The species reaches about 9 cm; sexually mature males are dark blue to blackish, females plain. It inhabits shallow inshore areas close to vegetation. In Lake Victoria the species is largely omnivorous, with insect larvae and small crustaceans as its main food, supplemented by algae and detritus. As a maternal mouthbrooder the female protects the young in her mouth. Owing to decline in Lake Victoria the species is considered Vulnerable (VU). It is harmless to humans.
