The blue diamond discus is one of the most highly sought after discus fish for tropical aquarium due to its beautiful color and luster.  The beautiful blue diamond discus is a cultivated discus that results from a recessive trait of the blue variety of turquoise discus. Whereas blue turquoise discus normally have striations throughout their bodies, those showing the recessive trait have transparent bodies without any markings. These turquoise discus with the recessive trait have been specially bred together to produce the blue diamond discus. 

The blue diamond discus has a solid blue hue over a pale body without any markings, and it has a noticeably shiny luster, hence the name “diamond.” Some blue diamond discus will have yellow coloring on their tail fins. The blue diamond discus also has unusual red eyes. Like all discus, it has a noticeably round shape, and its body is flat. The blue diamond’s fins are slightly thinner than most varieties of discus fish, but it still has the rounded shape that discus are known for. A mature blue diamond discus will be about 8” long, and it is almost as tall as it is long. 

Although in turquoise discus the lack of markings is recessive, when two blue diamond discus are bred, all of the fry will be blue diamonds. Cultivated discus are much easier to breed than natural discus, and with the proper water conditions, you could soon see your mature blue diamonds pairing off and mating. A family of these blue beauties will be a treat to enjoy in any aquarium.
