They belong to the genus Symphysodon, which contain basically three species: Heckel Discus (S. discus), Green Discus (S. aequifasciatus), and Blue and Brown Discus (S. haraldi). Apart from these natural species, there are various types of man-made discus fish that are produced through selective breeding and natural mutations.

How to Care for Discus Fish
Keeping discus fish is not easy, therefore, make sure you have prepared your fish needs. Let’s take a look at some tips on how to care for discus fish.
Habitat of Discus Fish
The natural habitat of the disc is characterized by three features: the water is relatively warm (29-34 ° C); depth is at least 1.5 meters; and the water is soft (not measurable hardness) and acidic (pH 4-5).
Filtration must be mechanical and biological. Partial replacement of water should be carried out with conditioned fresh water; The temperature difference between the new water and the aquarium water should not be more than 2-4 ° C and the new water should always be cooler, not warmer than aquarium water.
This fish food is generally live feed or frozen feed. For example tubifex, bloodworm, brine shrimp, corethra, gammarus.
However, professional carers feed him with branded feed, or with a variety of minced meat which includes beef heart, shrimp and shellfish, fillets, nettle, vitamins, various vegetables.
The disc grows to a width of 15-20 cm. They are not fast swimmers, and usually glide quietly through their habitat. The minimum aquarium size for a pair can be considered 60 x 60 x 60 cm, and more fish require a larger aquarium.
The depth of the aquarium should not be less than 50 cm, otherwise the fish will become nervous. The aquarium should provide plenty of cover (swamp wood, large vegetation) and have a smooth river sand substrate at least in some places, and fish will be happy to forage through this.
Unlike other cichlid species, discus is a peaceful and kind-hearted species. It is not a predator and does not dig into the aquarium substrate like other cichlids.
Discus are herd fish so they prefer to live in groups of at least 6 species and hardly stand on their own.
The difficulty in selecting a tank mate for discus is that the fish are slow, eat slowly and live in water with fairly high temperatures for other species.
Because of this and also to prevent possible infection, fish are often kept in separate tanks.
However, if you still want to include some friends in the aquarium, you should consider the following fish: neon tetras, ram cichlids, clown loaches, remmy nose tetras, congo tetras, cardinal tetras, and other catfish and putts, for example. Pterygoplichthys gibbiceps to keep the tank clean.
