Golden Julie
Julidochromis ornatus
Cichlidae
About
The golden julie is one of the smaller Julidochromis cichlids, a slender, elongate rock-dweller endemic to the rocky littoral zone of Lake Tanganyika. Its pale gold body is marked with three dark horizontal stripes, and it spends its days threading through crevices and hovering close to hard surfaces. It forms tight, long-lived monogamous pairs that fiercely defend a small cave territory, so it needs hard, alkaline water and plenty of rockwork to thrive.
Care
Keep a single bonded pair in hard, alkaline water (pH 8+) at 24-26 C over rockwork with many caves and crevices, in a tank of 90 L or more. Peaceful enough with unrelated tankmates but relentlessly territorial toward its own kind, so avoid keeping multiple pairs unless the tank is large.
Diet
Omnivorous micropredator that gleans small invertebrates and biofilm from rock. Offer small sinking foods and frozen or live micro-foods, with a little vegetable matter; feed modestly.

Telling males from females
What works for this species, most reliable first.
- Extended finsStrong · from about 8 months, and later in a suppressed male
On many cichlids and killifish the male's dorsal and anal fins draw out into trailing points as he matures, while the female's stay rounded.
- VentingA hint only · only on a mature fish, easiest when she is in breeding condition
The method breeders use when the answer has to be right. Hold the fish upside down in a wet hand or soft net and look at the two openings ahead of the anal fin. The forward one is the anus; the one behind it is what you are reading.
- Adult sizeA hint only · only across animals of the same age
In many cichlids, catfish and loaches one sex simply grows larger — usually the male, though there are well-known reversals.

Frequently asked questions
- What tank size does a Golden Julie need?
- A Golden Julie needs an aquarium of at least 90 litres (23.8 US gallons) with a footprint at least 75 cm (29.5 in) long — for this species, swimming length matters as much as raw volume.
- What water parameters does a Golden Julie need?
- Golden Julie does best at 23–27 °C (73.4–80.6 °F), pH 7.5–9 and a general hardness of 10–25 °dGH.
- Is the Golden Julie suitable for beginners?
- Golden Julie sits in the middle of the difficulty scale — manageable for a careful beginner who has done the reading, but it has specific needs worth researching first.
