Heterotilapia

Heterotilapia is a genus of cichlid fish that are native to rivers from Guinea-Bissau to Liberia in tropical West Africa. Formerly considered a subgenus of Tilapia, in 2013, it was elevated to genus rank. They are medium-large cichlids, up to about 20–30 cm (8–12 in) in standard length depending on the species, and with a distinctive dark-and-light banded pattern. They are substrate spawners and brooders (not mouthbrooders as some other tilapias). H. buttikoferi is a common species that also has been introduced outside its native range, but H. cessiana is highly localized and critically endangered.
