There are a couple different peacocks with this coloration. Auloncara baenschi and Nimbochromis venustus have yellow bodies and blue faces. In any event, even individual species can vary in coloration due to where they were collected. They can alos hybridize. Peacocks have a pretty wide color range but a lot of them are as beautiful as this one. Red Empress have the blue head and a red body. Any of the Auloncara, Copadachromis, Nimbochromis should give you good color. If you have more than one male of the same species, not enough females, or there adult coloration is similar, you will probably only have one colored male. You can either have a species tank with one male and 3 or 4 females, or you can try a bachelor tank with all males of somewhat different coloration.
