Aulonocara nyassae

The Nyassa peacock is only aggressive towards conspecifics and until a hierarchy establishes itself among the males. It requires a tank large enough for unrestricted swimming, with rockwork and a sandy substrate. After laying her eggs on a stone, the female incubates them in her mouth, where even free-swimming fry will retreat if threatened. There are several varieties of A. nyassae, some of which could well be different species. Size: 12 cm.
