Overview
Haplochromis microdon is a species of cichlid endemic to Lake Victoria. It is critically endangered, though it may now be extinct. This species can reach a length of 14.8 centimetres (5.8 in) SL.
Haplochromis microdon faces severe threats from the introduction of Nile perch (Lates niloticus) into Lake Victoria, which has caused dramatic population declines through predation and competition. Eutrophication from agricultural runoff and sewage has degraded water quality and reduced oxygen levels in the lake's deeper waters where this species historically occurred. Overfishing and destructive fishing practices have further reduced population numbers and degraded critical breeding habitats.
Habitat
Haplochromis microdon is endemic to Lake Victoria in East Africa, where it historically inhabited deeper waters and rocky substrates. The species preferred areas with moderate depths and complex bottom structures that provided shelter and feeding opportunities.
