Overview

The masked julie is a small, mostly peaceful cichlid from Lake Tanganyika that keeps to the rocks near the bottom. Keeping it is easy.

Did you know

A settled pair of masked julies often spawns again and again in the same crevice. Over time, the pair builds a small, stable family group in one corner of the tank.

Caring for the masked julie

A bonded pair of masked julies does well in a tank as small as 20 gal (75 L). Give them lots of rock and caves.

Keep the water hard and alkaline, at 75 to 81°F (24 to 27°C) and a pH of 7.8 to 9.0. Feed small frozen and dry foods, such as cyclops, brine shrimp and fine pellets.

Masked julies are peaceful toward other fish but defend their own crevice, so give tank mates their own space. Keep only one julie species per tank, because the different species readily crossbreed.

They are cave spawners that stick their eggs to the roof or wall of a rock crevice. Pairs are strongly bonded, and both parents guard the fry. Breeding them is easy.

Good to know

The masked julie, Julidochromis transcriptus, is the smallest of the julie cichlids in the family Cichlidae. Its black and white ladder pattern breaks up its outline against the stones.

In the wild

The masked julie lives tucked into rock cracks along the rocky northern shorelines of Lake Tanganyika, in East Africa. It moves in a slow, deliberate way, often hugging vertical rock faces.
