depends on the fish and the corals you house I would say. We have a raccoon and a pyramid butterfly in our tank and they have been great. Although any time we add a new coral to the tank the raccoon goes and checks it out. I looks like he is nipping at it but we have never seen any visible damage to the corals and everything has really good polyp extension.
Our tank is sps only though, I wouldn't trust a butterfly with zoas, softies or lps.
