Care Guide

Tank Requirements

• Minimum Tank Size: 55–75 gallons for a small group (discus thrive in groups of 5+).

• Water Temperature: 82–86°F (28–30°C).

• pH Range: 6.0–7.0 (slightly acidic).

• Hardness: Soft water preferred (1–8 dGH).

• Filtration: Strong biological filtration with gentle flow—discus prefer calm water.

• Water Quality: Pristine water is essential; plan for 25–40% water changes weekly.

Behavior & Compatibility

• Temperament: Peaceful, social, schooling cichlids.

• Ideal Tankmates: Cardinal tetras, rummynose tetras, corydoras, small rasboras, German rams, and other calm species that tolerate warm water.

• Avoid: Fast, nippy, or aggressive fish (barbs, large cichlids, etc.).

Diet

• Primary Foods: High-quality discus pellets, beef heart blends, frozen bloodworms, brine shrimp, blackworms, and nutrient-rich flakes.

• Feeding Schedule: 2–3 small meals per day for adults; juveniles require more frequent feeding.

• Tip: Rotate foods to enhance growth and coloration.

Breeding
