Blue Discus (A Few Fascinating Facts)

Blue Discus

The Blue Discus, also known as the Brown Discus, is a type of cichlid fish. It comes from the eastern and central Amazon Basin rivers.

These fish live in black, clear, and whitewater areas, but they prefer calm waters like floodplains and flooded forests.

Blue Discus fish need warm water (78°F to 86°F) with a pH level between 5.0 and 8.0. They can grow up to 6 inches long in the wild but may reach 9 inches in captivity.

These fish are often kept in aquariums. They like deep rocky areas with crevices and roots for hiding.

Blue Discus usually swim in groups but become territorial during the breeding season.

Their diet consists of insect larvae, insects, and small water creatures called planktonic invertebrates.

To keep Blue Discus in an aquarium, have at least five of them together. For breeding pairs, use smaller tanks. The minimum recommended tank size is about 47 inches long (120 cm).
