Let me quote liveaquaria.com "It is best housed in very large reefs, or in peaceful community tanks. It should be kept singly, not with conspecifics or similar butterfly fish, and should not be kept with any stress-inducing fish. Caution should be exercised if housing these fish in a reef aquarium. They may pick on invertebrates, especially anemones and feather dusters. They are an excellent fish when used to control aiptasia, or glass anemones, in the reef aquarium.
I tried to keep them in my 180 Gal
. with Tangs and triggers with the same results.
