Blue Diamond Discus
Blue Diamond Discus
Blue Diamond Discus (Symphysodon aequifasciatus) is a solid, pattern-free discus with an even metallic powder-blue color from nose to tail — one of the cleanest and most striking of the solid strains. Discus are native to the slow, warm, soft blackwater and clearwater rivers of the Amazon basin. Our discus are farm-raised, well-acclimated stock that adapt well to home aquariums.
⚠ Water Quality: Discus need warm, very clean water. Plan on large, frequent water changes (25–50% weekly or more) and stable temperature. Rapid swings in temperature or water chemistry are the most common cause of stress.
Discus are peaceful, social cichlids that do best in a group of 5 or more; kept singly or in pairs they often become shy and stop eating. A tall tank of at least 55 gallons with gentle flow, subdued lighting, and some driftwood or broad-leaved plants gives them security, and young fish grow fastest with a bare or lightly planted setup.
Good tankmates are calm, warm-water fish such as Cardinal and Rummynose Tetras, Corydoras (sterbai tolerate the heat best), Bristlenose plecos, and peaceful dwarf cichlids. Avoid fast, boisterous, or fin-nipping fish that outcompete discus at feeding time.
Feeding & Care Tip: Feed small meals 2–3 times a day. A quality discus granule or pellet makes a good staple, rotated with Hikari Frozen Bloodworms and Hikari Frozen Baby Brine Shrimp for color and condition. Remove uneaten food after a few minutes to protect water quality.
