Heniochus singularius

These fish are quite peaceful to most other fish, but might haress similar looking fish. Juveniles are often solitary and shy, adults often live solitary, in pairs or in small groups in lagoons and seaward reefs close to vertical coral growth. In an aquarium they can best be kept alone unless a proven pair can be found. They're obligate corallivores, meaning they feed mainly on corals and do need them to stay healthy. This makes them not suitable for a fish-only tank and they will do best in a large reef tank stocked with fast growing corals. Do keep in mind that they will do considerable damage to these corals! A real specialist fish!
