The convict julie (Julidochromis regani) is a cichlid species in the subfamily Pseudocrenilabrinae family endemic to Lake Tanganyika.

Julidochromis regani are small-growing dwarf cichlids and easy to spawn and care for if their basic needs are fulfilled.

Hybridisation with Chalinochromis (which might belong in Julidochromis) and Telmatochromis is suspected, and it is common enough in Lamprologini[3] to better avoid keeping more than one species of this tribe per aquarium.

The tank should be decorated with rocks to form caves and passageways as shelter; like many other Rift Valley cichlids, they tend to be territorial and somewhat aggressive.

Breeding is, as usual in these social and intelligent fishes, easiest achieved by acquiring a stock of juveniles and letting them grow up together until pair-bonds are established.
