While Reef Safe should mean that it won't eat my corals and clean up crew, you are still running a chance no matter what you put in the tank. Just because someone has something that itsn't eating corals and cleaners in their tank, doesn't mean you are going to get that lucky with a different one of the same species. I'm with Steve. Do more research and make sure that the Reef Safe behavior is common for all of them in that class.
