Males are brilliant sky blue to dark blue; the colors show a "checkerboard" pattern with alternating light and dark patches; several light-colored "egg spots" on their anal fin; females and juveniles bright yellow-orange in color (Ref. 44091).

Life cycle and mating behavior
Maturities | 繁殖 | Spawnings | Egg(s) | Fecundities | 幼生
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).
