This fish is of minor importance as a food fish in addition to its use as an aquarium fish. In an aquarium, the disk tetra grows to 40 cm (16 in). It prefers a pH of 5.0 to 7.0 and a temperature of 23 to 27 °C (73 to 81 °F). They are related to pacus and piranhas. They primarily eat fruits, small fish, crustaceans, clams and snails. This fish is capable of delivering serious bites.[4]
