Julidochromis regani information and care sheet

Regan's Julie Cichlid Julidochromis regani, also referred to as Regan's julie cichlid or the zebra julie, is a small freshwater species endemic to Lake Tanganyika in Africa. This dwarf cichlid is characterized by its tan to brown body color patterned with interesting dark vertical barring reminiscent of a zebra stripe pattern.

In their natural habitat, J. regani inhabits rocky regions close to shore, spending most of the day secreted away within small crevices and holes. At night they emerge to feed on tiny prey like insect larvae and zooplankton. Males are highly territorial and aggressive toward intruders.

Regan's julie cichlid reaches lengths of around 3 inches as adults. Sexual dimorphism is apparent, with males exhibiting more intense coloration and longer dorsal and anal fins used for displays. Females tend to be slightly smaller in size.

In home aquariums, provide these cichlids with plenty of rockwork and hiding places. While peaceful toward tankmates, conspecific aggression is common so they are best kept singly or in pairs. A 30 gallon tank mimicking Lake Tanganyika's alkaline water is ideal.

Though demanding in terms of habitat setup, the striking colors and behaviors of Julidochromis regani make them interesting aquarium residents for experienced cichlid keepers. Their vertical barred pattern is truly unique among Lake Tanganyika's diminutive julie cichlids.
