Most butterfly fish are not reef safe even thou someone might had him in a reef tank and was great with reef, one day he WILL turn on you .... I had a Klein butteryfly fish and was great in reef for about a year ,then one day he went ham on my reef ... I would stay away for butterfly fish all together in a reef just my personal opinion Good luck
