Introducing the Blue Diamond Discus: The Epitome of Elegance

The Blue Diamond Discus, a breathtakingly beautiful aquarium fish, is often regarded as the epitome of aquatic elegance. With its mesmerizing blue coloration and graceful, disc-shaped body, it is truly a sight to behold in any freshwater aquarium. This captivating species has become a favorite among hobbyist aquarists for its striking appearance and serene swimming style.

Scientific Name: Symphysodon aequifasciatus

The Blue Diamond Discus belongs to the species Symphysodon aequifasciatus, a close relative of the wild Discus fish. While the wild Discus displays a range of natural colors and patterns, the Blue Diamond Discus is a selectively bred variant that showcases a stunning blue body adorned with intricate white patterns.

Water Quality:

  • pH Level: 6.0 – 7.5
  • GH Level: 1-3 dGH (degrees of general hardness)
  • KH Level: 1-2 dKH (degrees of carbonate hardness)


The Blue Diamond Discus’s diet is as diverse as its beauty. To keep them healthy and vibrant, offer them a balanced diet that includes high-quality flakes and pellets. Supplement their meals with a variety of live or frozen foods such as bloodworms, brine shrimp, and daphnia. To enhance their vibrant coloration, incorporate spirulina-based foods into their feeding regimen.

Tank Mates:

These peaceful fish are excellent candidates for community aquariums. They coexist harmoniously with other calm and compatible species such as angelfish, neon tetras, and cardinal tetras. To avoid conflicts over food, ensure that their tank mates are of similar size.


Distinguishing between male and female Blue Diamond Discus can be challenging, especially when they are not actively breeding. Males are generally larger and may exhibit more pointed dorsal and anal fins. During the breeding season, males often display more intense colors and engage in territorial behavior as they court females.


Breeding Blue Diamond Discus can be a rewarding experience for dedicated aquarists. To encourage breeding, set up a separate tank with soft, acidic water conditions. The pair will select a flat surface, such as a leaf or vertical surface, for spawning. Once the eggs are laid, the parents will diligently guard and care for their fry, which initially feed on a special secretion from the parents’ skin.

Maximum Size and Longevity:

Under proper care, Blue Diamond Discus can attain a size of 8-10 inches (20-25 cm) in captivity. Their longevity is impressive, as they can live for 10-15 years or even longer. This makes them a significant and enduring presence in your aquarium, offering years of enjoyment to dedicated enthusiasts.

General Information:

The Blue Diamond Discus’s allure extends beyond its striking appearance. To maintain their health and vibrant coloration, it is essential to provide a stable environment and perform regular water changes. These measures help ensure that these exquisite fish continue to flourish and captivate admirers with their elegance.

A Fun Fact:

The Blue Diamond Discus’s remarkable blue coloration is not found in the wild. It is the result of selective breeding, a process that has transformed the natural Discus into a stunningly blue variant. This captivating transformation has made the Blue Diamond Discus a sought-after addition to aquariums worldwide, adding a touch of elegance and charm to aquatic landscapes.
