Blue Diamond Discus
Symphysodon aequifasciatus
Symphysodon aequifasciatus
The Royal Blue Discus occupies a distinguished place in the Discus hierarchy — a strain that bridges the gap between the intense, solid Blue Diamond and the more patterned turquoise varieties. Its coloration is a deep, regal blue with subtle horizontal striations that add depth and visual complexity without overwhelming the base color. The effect is a fish that appears to shift between solid blue and patterned blue depending on lighting angle and mood, making it endlessly fascinating to observe.

This strain traces its lineage to early German and Asian breeding programs that worked to intensify the natural blue iridescence found in wild Discus. Unlike the Blue Diamond, which was bred for complete pattern elimination, the Royal Blue retains just enough of the ancestral striping to create a nuanced, layered appearance. Many experienced Discus keepers consider it the most elegant of the blue varieties for precisely this reason.
Housing follows standard Discus requirements: a minimum 75-gallon aquarium, water temperature between 82 and 88 degrees Fahrenheit, pH of 6.0 to 7.0, and soft water. Groups of five or more are essential for social wellbeing. The Royal Blue pairs beautifully with contrasting warm-toned strains like Pigeon Blood and Red Turquoise in a mixed school, creating a display that showcases the full color spectrum available in modern Discus breeding.
Diet consists of Discus-specific pellets, frozen bloodworms, brine shrimp, and beef heart preparations. Feed two to three small meals daily. A high-quality, varied diet is critical for maintaining the depth and intensity of the blue coloration over time.
Weekly water changes of 30 to 50 percent are mandatory. Discus are unforgiving of lapsed maintenance, and the Royal Blue is no exception. The Fish Collection ships with insulated, heat-packed packaging and our absolute live arrival guarantee.

The Blue Diamond Discus is a selectively bred colour morph of the common Discus (Symphysodon aequifasciatus), prized for its solid, luminous cobalt-blue body free of the vertical stress bars typical of wild-type Discus. Widely considered the "king of the aquarium," Discus demand warm, pristine water, frequent feeding, and a calm social environment. This guide covers every element of Blue Diamond Discus husbandry — water chemistry, tank design, diet protocols, breeding, and disease prevention — drawing on The Fish Collection's decades of experience sourcing and maintaining show-quality Discus.
