On first sighting, the unique discus characteristics, including a solid blue body with sharp, distinctive markings, will steal your gaze.

The sharp blue detail results from selective breeding based on mating wild-caught Blue diamond specimens with the sharpest color to continue a long line of vibrant blue discus fish. 

This Malaysian native freshwater breed is unique, with thin oval bodies and elongated fins. Blue Diamond Discus’s appearance has made it one of the more prominent freshwater species purchased by hobbyists for aquariums. 

Size: Blue Diamond Discus can grow up to 8 inches for average adults. 

Ideal Tank Setup for Blue Diamond Discus

To achieve a successful aquarium setup for blue discus, you need a spacious tank with stable water flow and a sufficient filtration system to keep your water clean and toxins-free.

Blue Diamond Discus prefer to live in groups, which means they need a large tank with ample space to thrive and go about their activities without exposing them to stress or substandard water parameters.

But not to worry—the ideal discus tank conditions are listed below to make housing your freshwater pets easy for you. 

Minimum Tank Size55 gallons is recommended for a small group of discus typically made up of 4-5 of them. If you’re adding extra fish, the ideal ratio to maintain is 10 gallons per extra fish.
pH Level6.1- 7.5
Water Temperature79-870F
Softness1-4 dGH

Substrate and Decorations: Decorations and filter options are also essential in an aquarium setup for blue discus. Add dark substrate for color enhancing contrasts and decorations such as live plants ( Anubias, Taiwan Lillies, Hygrophila Salicifolia, Java Ferns, Swords) and driftwood to create a natural habitat and serve as a hiding spot for fry. 

For a filter, a gentle type like the very trusted sponge filter will keep your water clean by trapping particles and providing ample space to break down harmful chemical compounds like ammonia and nitrates in the water. This filter type also creates a gentle circulation of water that reduces stress for your discus. 

Feeding Blue Diamond Discus for Optimal Health

Here’s a discus fish diet guide for you! 

The Blue Diamond requires unique dietary needs that include high-quality pellets, frozen foods, and occasional live treats like blood worms and white worms. Feeding Blue Diamond Discus a balanced diet contributes in no small measure to their dazzling blue color vibrancy and health, so prioritize foods rich in protein and fat percentages higher than those of most typical freshwater fish. 

Feeding frequency: While you may be tempted to provide an endless supply of nutritious food for discus, you must maintain strict feeding schedules and portion control. Overfeeding your discus fish may lead to limited tank activity and disease exposure. 

Pro tip: Feed your Blue Diamond Discus at most 2-3 times per day to meet their daily balanced diet quota.

The reproduction of Blue Diamond Discus requires maintaining low-stress environments and paying close attention to tank details, such as water temperature, water quality, and proper lighting conditions. 

Water Temperature80-860F
Water QualitypH level of 5.5 – 6.
LightingLow lighting level to eliminate stress and mimic natural environment for breeding

Breeding Blue Diamond Discus commences with a pair exhibiting courtship traits such as swimming together. When the female is ready to spawn, the pair will clean the chosen spot, after which the female lays a trail of eggs. The male fertilizes them, and both parents secure the eggs, fanning them simultaneously to keep them oxygenated.

The eggs usually hatch in 48-72 hours, and the fry attaches to their parents’ bodies to extract nutrients from the mucus coating for up to 2 weeks. After that, the aquarist is advised to move them to a separate tank for safety. 

Blue Diamond Discus fish fry care: 

  • Separate fry from the adult discus as soon as they become active to protect them from being preyed on, harmed, or chased by the bigger fish in the tank. 
  • Supply your discus fish fry with a finely crushed flake or special fry food to bolster the nutrients they get from their parents’ bodies. 
  • Perform frequent water changes and closely monitor ammonia and nitrate levels in your tank. Unstable water parameters will kill your fry faster than aggressive adult discus fish
  • Include live plants and rocks in your aquarium setup for discus breeding; these will serve as hiding spots for the fry when they hatch. 

Choosing Compatible Tank Mates for Blue Diamond Discus

When choosing compatible fish for discus tanks, it is important to focus on peaceful discus companions that thrive in similar water conditions and are preferably the same size as your Blue Diamond Discus to help foster a socially balanced environment. 

Compatible species: For the ideal Blue Diamond Discus tank mates, introduce small-sized peaceful species like Neon Tetras, Bronze Corydoras, or any other Corydoras catfish type, and Plecos.

Incompatible Species: Avoid large and aggressive fish like Tiger Barbs, Large Plecos, Goldfish, and large Cichlids, as they may become territorial, too hyperactive in a discus tank, or compete with your Blue Diamond Discus for food.
