Congochromis

Congochromis dimidiatus is a small cichlid of the central Congo basin in the Republic of the Congo and DR Congo, described from Bangui on the Ubangi. Most older aquarium literature knows it as Nanochromis dimidiatus. Its dark flank stripe runs into the caudal fin, which separates it from C. sabinae. Many museum records were identified before the genus was split, so some may belong to other species.

Congochromis sabinae is a small cichlid from rainforest streams in the Republic of the Congo, northeast Gabon and northern DR Congo. It was in the hobby before its description under names such as Nanochromis sp. 'Bamanja', 'Genema' and 'Bloody Mary', and continues to be mislabelled N. squamiceps. The dark midlateral stripe stops short of the caudal fin. At the type locality the water was stained reddish brown, with a pH of 4.0.
