Discuss Cobalt Blue (5-6 cms) | Single

The Discus Cobalt Blue (5-6 cm) is a striking freshwater fish known for its captivating cobalt-blue coloration and elegant appearance. Belonging to the Symphysodon genus, this fish originates from the slow-moving waters of the Amazon River Basin, where water conditions are soft and slightly acidic. At this juvenile stage, the Cobalt Blue Discus showcases vibrant hues of metallic blue, which will intensify as it matures. Its flat, rounded body and flowing fins make it an eye-catching addition to any aquarium, especially in a well-maintained community tank or a planted aquarium.

Size: Measuring between 5-6 cm, this Cobalt Blue Discus is in its juvenile stage. As it matures, it will grow to a larger size of up to 15-20 cm (6-8 inches) in adulthood.

Color: The fish exhibits a brilliant metallic cobalt-blue hue, sometimes with faint vertical lines or patterns that shimmer under aquarium lighting. The intensity of the blue will deepen as the fish grows, making it a showpiece in the aquarium.

Shape: Discus fish are known for their unique disc-like, flattened body shape. The Cobalt Blue variant is no exception, with a perfectly round body and long, elegant fins, giving it a graceful, floating appearance.

Tank Size: A tank of at least227 to 340 litres is recommended, especially if keeping more than one Discus. Since Discus are social fish, they are happiest in groups of five or more, which helps them feel secure and reduces stress.

Temperature: The ideal water temperature for Discus is 28°C to 30°C (82°F to 86°F).

pH: They prefer slightly acidic to neutral water with a pH range of 6.0-7.0.

Water Hardness: Soft water is ideal, with a hardness level of 1-8 dGH. They are sensitive to water with high mineral content.

Filtration: A high-quality filtration system is essential to maintain clean, stable water conditions. Regular water changes  are necessary to keep nitrate levels low, as Discus are sensitive to poor water quality.

Lighting: Moderate lighting is preferred, as overly bright lights can cause stress. The blue coloration of the fish is best highlighted under soft or moderate lighting.

Aquascaping: Discus thrive in aquariums with plenty of hiding spots and natural decorations such as driftwood, rocks, and live plants like Amazon Swords and Java Ferns. Provide ample swimming space, as well as shaded areas where the fish can retreat when needed.

Social Nature: Discus Cobalt Blue are peaceful and social fish. They are best kept in groups of their own kind or with other non-aggressive species. When kept alone or in small numbers, they may become stressed or exhibit shyness.

Tankmates: Suitable tankmates include other peaceful fish like tetras, dwarf cichlids, corydoras catfish, and small plecos. Avoid housing them with aggressive or fin-nipping species, as Discus are slow swimmers and can be easily harassed.

Feeding: Cobalt Blue Discus are omnivores and require a varied diet to maintain optimal health and coloration. Offer high-quality Discus pellets, flakes, and frozen or live foods such as bloodworms, brine shrimp, and daphnia. Juvenile Discus (5-6 cm) need regular feedings to support their growth, typically 2-3 times per day.
