The Albino Blue Diamond Discus (Symphysodon aequifaciatus) is a member of the Cichlid family, originally native to the Amazon River and some of its tributaries. All Discus are tall bodied and somewhat static, and so they do best in aquariums that are tall. We suggest displays that are at least 20 inches tall, and 55 gallons as an absolute minimum for a small group of five. Though 90 and 110 tall aquariums don't take up much more footprint and offer a lot more volume and vertical space. Displays should have gentle, diffuse flow and plenty of cover. Discus like slow moving water with lots of branches and vegetation in the wild, and these preferences still exist for captive bred and raised specimens.
