Chaetodon speculum

Chaetodon speculum, commonly known as the Mirror butterflyfish, is a medium-sized butterflyfish. Their body is bright yellow with the typical black vertical eye bar. On their body they've a large black patch with washed out edges.

These fish are quite peaceful to most other fish, but might haress similar looking fish. They live mostly solitary as juveniles between branching corals and the more they mature, the more they move around, either solitary or in pairs. Most common in areas rich in anemones and hydroids. In an aquarium they can best be kept alone unless a proven pair can be found. Although this is a beautiful fish to watch, they're obligate corallivores and thus need to eat corals to survive. This makes them not suitable for a fish-only tank and they can only be kept in a large tank with a lot of fast growing corals where considerable damage to the corals is accepted. Feeding them a varied diet of live and frozen meaty foods can help to minimize the damage to the corals if alternative food is accepted. A real specialist fish!
