Care basics

Aulonocara jacobfreibergi is one of the larger peacocks, and it is sold in several color forms. The well known "Eureka Red" is a line bred form with a red body and blue head.

Peacocks sift sand for small invertebrates, so give them soft sand and open space. Do not keep them with mbuna, and avoid other Aulonocara because they can crossbreed.
