Marlier's Julie (Julidochromis marlieri)
22–25°C · pH 7.5–9 · 150L

A golden rock-dwelling Tanganyika cichlid for hard, alkaline aquariums with caves, crevices and a compatible pair. Territorial but rewarding in the right setup.
Adult size is the maximum length this species reaches at full maturity (scientific sources). The livestock you receive will be younger and smaller — pick a size variant above for the actual shipping size. Photos are AI-enhanced, so the animal may show subtle colour or marking differences.

Maintain these water conditions for optimal health and vibrant colors
Golden Julie (Julidochromis ornatus) is a small Lake Tanganyika rock cichlid with a bright yellow body and bold horizontal markings. It is best kept as a compatible pair in a hard, alkaline aquarium with caves, crevices and clear territory boundaries.
| Scientific name | Julidochromis ornatus |
|---|---|
| Adult size | About 8cm |
| Minimum aquarium | 80 litres or larger for a compatible pair |

| Diet | Small cichlid pellets, frozen foods, insect larvae and spirulina-rich foods |
| Temperament | Semi-aggressive around caves and breeding sites |
Build rockwork with narrow crevices and line-of-sight breaks. Do not crowd several pairs together in a small tank; once bonded, Golden Julies can defend a cave strongly and may harass weaker fish.
