These beautiful and graceful fish can grow to be quite large, and therefore require a larger tank, a minimum size of 25 gallons.
Discus are not recommended for beginners, and instead should only be kept by experienced aquarists.
They can be housed with other fish that require the same water conditions, as long as they are not aggressive.
Discus will take a variety of foods but are carnivorous in nature. The best diet for them consists of beef heart and blood worms supplemented with flakes to provide vitamins and minerals.
