Maternal mouthbrooders; males establish territories and maintain a harem of females; female deposits eggs and picks them up in the mouth for incubation; male spreads out his anal fin showing the "eggs pots"; the females mistake these spots for her eggs and try to also take them inside her mouth; the male then releases his milt and the female takes them in, thus fertilizing the eggs inside her mouth (Ref. 44091).
