It should be avoided as far as possible to keep together with the butterflyfish that are too large. The eight-line butterfly is very gentle in feeding, and it is generally not easy to grab. In addition, although this fish is only 300px, it still likes to attack corals, and it is impossible to polyculture in a reef ecological aquarium.
