Discus Aquarium Care Guide

Keeping Discus in an aquarium requires the right conditions.

Aquarium Information

• Care level: advanced
• Temperament: peaceful
• Diet: omnivore
• Minimum tank size: 75 gallons (280 liters) for a group of 5-6 adults
• Compatibility: Best kept in species-specific tanks or with very peaceful, similarly sized, and temperature-tolerant tankmates such as cardinal tetras, rummy-nose tetras, and certain dwarf cichlids. Avoid aggressive or fin-nipping species.
• Special requirements: Discus require pristine water quality, stable parameters, and a well-established filtration system. They thrive in planted tanks with driftwood and subdued lighting, mimicking their natural habitat. They are schooling fish and should be kept in groups of at least 5-6 individuals to reduce stress and encourage natural behavior. Daily water changes (25-50%) are often recommended, especially for juveniles.
