Symphysodon, colloquially known as Discus, is a genus of Cichlids native to the Amazon River Basin. Due to their distinctive shape and bright colors, discus are popular as freshwater aquarium fish, and their aquaculture in several countries in Asia is a major industry. Discus fish are sometimes referred to as pompadour fish.
Although the discus freshwater fish is a peaceful, schooling species, it is best kept in a species aquarium because its temperature needs are much higher than most other species can stand. However, the discus fish will also do quite well when kept with other peaceful, heat-loving species, such as cardinal tetras, clown loaches and T-bone rasboras. It should not be kept with angelfish, which are prone to parasitic infestations/diseases that may be fatal to the discus.
