Blue Discus Overview

The Blue Discus (Symphysodon aequifasciata haraldi) is often hailed as the "king of the aquarium" due to its captivating beauty and elegance. These stunning fish are recognized for their unique spherical shape and relatively flat bodies compared to other cichlids. With a range of vibrant color variants available, Blue Discus thrive in peaceful environments. They can be kept in species tanks or alongside other docile companions. It is crucial to avoid housing them with aggressive or fast-moving fish, as this may lead to stress and affect their health.

Tank Requirements

Blue Discus require spacious aquariums with efficient filtration to maintain excellent water quality. A minimum tank size of 200 liters (53 gallons) is recommended for a small group, as they appreciate swimming space. Frequent water changes are essential to replicate their natural habitat, which is characterized by soft, clean water. Aim to maintain water temperatures between 27-30°C (80.6-86°F), with a pH range of 5.5 to 7.5 and water hardness between 0 to 8°N (0 to 142.86 ppm) for optimal health.

Food and Feeding

Blue Discus are omnivores and require a varied diet to thrive. Their staple diet should consist of high-quality flakes or pellets, complemented by protein-rich treats such as bloodworms, brine shrimp, mosquito larvae, and Spirulina-based foods, along with some plant-based options. Providing several feedings a day in small amounts will help ensure they receive adequate nutrition while keeping the water clean.

Breeding

Breeding Blue Discus can be a rewarding experience for aquarists. These fish are relatively easy to breed once they have paired off and matured sexually. To encourage spawning, provide a spawning cone or flat surface in the aquarium. Both parents exhibit devoted care, protecting their young and feeding them with secretions from their skin. After spawning, the fry will typically hatch within 48 to 72 hours, so maintaining a stable and clean environment is crucial for their development.

Compatibility and Tank Mates

Blue Discus are known for their peaceful temperament, making them suitable for community tanks with other gentle fish. Ideal tank mates include tetras, peaceful cichlids, and other small to medium-sized fish that share similar water requirements. Avoid housing them with aggressive or overly active species, as this can lead to stress and health issues.

Short Description

The Blue Discus (Symphysodon aequifasciata haraldi) is a striking cichlid native to South America. Reaching sizes of 13 to 15 cm (5.12 to 5.91 inches), these fish are celebrated for their vibrant colors and peaceful nature. Blue Discus thrive in well-maintained aquariums with stable water conditions and a high-protein diet. Keeping them in groups of five or more promotes social behavior and healthy development.
