When I decided to set up a Tanganyikan rock-dwelling aquarium, Julidochromis transcriptus 'Kalemie' was a natural choice. This variant is very similar to the standard transcriptus, but its compact size makes it ideal for smaller setups.
Behavior and Social Structure
This species is a typical family cichlid from Lake Tanganyika. It thrives best in a species-only tank where it can exhibit its natural behavior without interference. When I first kept them in a 75-liter tank, a pair formed quickly, and fry began appearing in the rock crevices. One of the most fascinating aspects of this fish is the ability to keep multiple generations of fry together with the adults. However, be aware that individuals may occasionally be "ostracized" from the colony; these should be removed as they are rarely re-accepted.
Tank Setup and Coexistence
I have also kept them in a 148-liter tank with other Tanganyikan cichlids. While they coexisted well, there was noticeably more aggression, and the survival rate of the fry dropped significantly due to the other inhabitants. They are now back in a species-only setup, resulting in a population boom of fry of all sizes. The decor should always consist of plenty of rock formations with narrow crevices where the fish can hide and deposit their eggs.
Care and Coloration
J. transcriptus 'Kalemie' is a cave spawner that prefers hard and alkaline water ($pH$ 8.0-9.0). A unique feature to look for is the delicate blue edging on the fins, which truly stands out under the right lighting. They are relatively easy to feed and accept most quality foods, though they greatly appreciate frozen foods like cyclops or brine shrimp.
