Hemitaurichthys zoster

These fish are quite peaceful to most other fish, but might haress similar looking fish. They generally live in large schools in open water off the reef edge. In an aquarium they can best be kept alone unless the tank is large enough for a small group or a proven pair can be found. They're real omnivores, but mainly feed on zooplankton and algae. But they're also facultative corallivores, meaning they do eat but don't need corals. Although one of the most reef safe butterflyfish, this still makes them a risk in a reef tank though! So either keep them in a fish-only tank or accept the damage they can do to corals. Feed them a varied diet of live and frozen meaty foods (copepods if available) several times a day because they're not build for one meal a day!
