The numerous Oreochromis species are maternal mouthbrooders, meaning only the female looks after the eggs and fry, with the male offering no protection or help at all. Instead, they form leks where they compete with one another for further opportunities to mate with females. By contrast, most of the far fewer Sarotherodon species are biparental mouthbrooders, with both parents protecting the eggs and fry. A few, such as Sarotherodon melanotheron, are paternal mouthbrooders, with only the male caring for the eggs and fry. In addition, some species usually placed in Oreochromis might belong into Sarotherodon.[2] Either this is incorrect due to hybridization effects, or they are not maternal mouthbrooders, or the diversity of brood care is even higher among these cichlids than hitherto believed. GeneraThe following genera are classified within the Oreochromini:[3]
