Discus (Symphysodon sp.) – Care Guide

Discus are universally recognised as the “King of the Freshwater Aquarium” — symmetrically round, laterally compressed, and available in a breathtaking array of varieties: Checkerboard, Galaxy Turquoise, Leopard Spotted, Red Batata, Sakura, Red Snakeskin, Alenquer, Albino, and Panda Bulldog. From the warm, acidic blackwater tributaries of the Amazon Basin, Discus demand precise water conditions but reward dedicated keepers with an incomparably elegant display. Social fish that must be kept in groups.

Temperature stability and water quality are the twin pillars of Discus keeping. Nitrates must stay below 20 ppm — this typically requires 2–3 partial water changes per week (25–30% each). Use an RO unit or soft water source where possible. Feed 3–4 times daily in small amounts. Never use copper-based medications. Discus are dedicated parents — they care for fry and feed them via skin secretions. ⚠ Never add copper-containing products to a Discus tank.
