I have a butterfly heniochus. She was a nice add to the tank. Alot of the heniochus that I read about are not reef safe
the one I got is reef safe, but is hard to tell. There are two diff type of butterfly heniochus one that's not reef safe and one that is. Mine is a butterfly heniochus D, the D is a scientific name. Well starts with one anyways. The one that is not reef safe is a butterfly heniochus A. Hope this helps.
