JULIDO MARLIERI

Julidochromis marlieri, also known as the Marlier’s Julie, is a species of cichlid native to Lake Tanganyika in Africa. They are popular in the aquarium trade due to their striking appearance and interesting behaviors. Here’s a detailed care guide for Julidochromis marlieri:

Tank Size and Setup

• Tank Size: A minimum of 30 gallons is recommended. Julidochromis marlieri are territorial and require ample space to establish their territories and avoid aggression.
• Aquascape: Create a rocky environment with plenty of caves and crevices where they can hide and establish territories. Use rocks to create a natural-looking habitat that mimics their native environment.
• Substrate: A substrate of fine gravel or sand is ideal. They are not bottom dwellers but will occasionally forage on the substrate.
• Lighting: Moderate lighting is sufficient. The focus should be on creating a natural habitat with plenty of shaded areas provided by the rock formations.

Water Parameters

• Temperature: Julidochromis marlieri prefer water temperatures between 76-82°F (24-28°C). Use a reliable heater to maintain a stable temperature.
• pH: They thrive in slightly alkaline water, with a pH range of 7.5 to 9.0.
• Hardness: They prefer hard, mineral-rich water, with a general hardness (GH) of 10-15 dGH.
• Water Quality: Maintain excellent water quality with regular water changes (20-30% weekly). Ensure ammonia and nitrite levels are at 0 ppm and keep nitrates below 20 ppm. Use a high-quality water conditioner to treat tap water before adding it to the tank.

Filtration and Water Flow

• Filtration: Use a filtration system that provides both mechanical and biological filtration. A canister filter or a hang-on-back filter works well.
• Water Flow: Moderate water flow is ideal. Ensure the filtration creates a current that mimics the natural lake environment without creating strong currents that could stress the fish.

Feeding

• Diet: Julidochromis marlieri are omnivorous and will accept a variety of foods. Offer high-quality cichlid pellets or flakes as their staple diet. Supplement with live or frozen foods such as brine shrimp, bloodworms, and daphnia.
• Variety: Providing a varied diet ensures they receive all necessary nutrients and helps maintain their health and coloration.
• Feeding Frequency: Feed them once or twice a day. Offer only as much food as they can consume within a few minutes to avoid overfeeding and maintain water quality.
