Symphysodon (colloquially known as discus or discus fish) is a genus of cichlids native to the Amazon river basin in Brazil.Due to their distinctive shape, calm behavior, many bright colors and patterns, and dedicated parenting techniques, discus are popular as freshwater aquarium fish, and their aquaculture in several countries in Asia (notably Thailand) [1] is a major industry.
