Lemon Jake
Aulonocara jacobfreibergi
Also known as: Fairy Cichlid
A peacock cichlid with bold fin margins and a long history in the hobby.

About
The fairy cichlid (Aulonocara jacobfreibergi) is one of the longest-standing members of its genus in the aquarium world, and its popularity makes sense once you see an adult male in full color. It can be distinguished from most other peacock cichlids by the broad pale margins running along the dorsal, anal, and caudal fins, plus a more deeply forked tail and a noticeably larger adult size. In Lake Malawi, populations vary by location. Northern fish tend to occupy boulder-strewn rocky zones while southern populations favor mixed habitats where males claim small caves as territory. There are also selectively bred forms including albino and 'eureka' variants, along with a naturally occurring yellowish form from Undu reef sometimes called 'lemon jake'. In the aquarium, this species carries a reputation as less easygoing than some of its relatives. Males will react aggressively toward fish with similar color patterns, and housing multiple males together is asking for trouble. A single male kept with four to six females is the standard approach. Tankmates like Copadichromis, Placidochromis, or the calmer Labidochromis caeruleus can work, but most Mbuna are too boisterous, and other Aulonocara species risk hybridizing. It is a maternal mouthbrooder with a well-documented breeding routine, and fry can sometimes appear even in a community setup.
