The intensity of the blue will depend on the discus' overall health, mood, and genetics. Discus are not the most hardy of fish and require both stable and clean water conditions and should be housed in an aquarium with adequate filtration. They are a peaceful fish aside from during spawning, and will shoal together. They are a popular addition to freshwater community tanks or even kept in single species tanks. During spawning they may become territorial and aggressive. They should be fed meaty preparations such as bloodworms (both live and freeze dried), tubifex, and other live and frozen foods, as well as pellet and flake foods. There are pellet foods specifically designed for them on the market.
