Discus are members of the Family Cichlidae and are sometimes referred to as “King of the Aquarium” because of their majestic beauty and regal colors. At least three species have been described, although debate continues over the validity of several assigned scientific names. Wild caught discus can be challenging to keep, due to their specialized water chemistry and dietary needs, however, most discus sold today are captive bred and are much easier to keep. That said, they are not for beginners, for a variety of reasons. Through selective breeding, numerous color varieties are available and more continue to be developed. For care and maintenance purposes, the information presented here can also be used for wild caught P. scalare and P. altum angelfish, as well as Uaru.
Discus are colorful, graceful and charismatic tank inhabitants. Discus are considered to require a higher level of care than other aquarium fish. Their basic requirements are a larger aquarium (3ft+ is recommended) and stable, clean water. For this reason alone they are not recommended for the beginner aquarist. Discus can be housed with many any other fish as long as they require the same water conditions.
