Haplochromis aelocephalus Greenwood 1959

Mouthbrooder.

Inhabits areas with firm substrate (sand and rock) (Ref. 4983). Gut contents showed that this species preys on a variety of invertebrate animals and possibly even small fish. Predominant food organisms were insects (esp. dipterous larvae but also Ephemeroptera & Trichoptera larvae). The non-insect food were fish, oligochaete worms, prawns, plant tissue, ostracods, and fragments of lamellibranchs & gastropod shells (Ref. 558).

Haplochromis aelocephalus is a species of cichlid endemic to Lake Victoria, but has not been seen since 1985. It may be extinct, but is maintained as Critically Endangered by the IUCN in the small chance that a tiny –but currently unknown– population survives. This species can reach a length of 12 centimetres (4.7 in) SL.
