I always though peppermint shrimps were reef safe. Reccently I introduced a peppermint srhimp into my tank. I found him on top of my LSP and GSP an my Xenia.

From what i have read, only pepperment shrimp from a certain area will eat aiptasia. When you buy them its a gamble with trying to get one. If your pepperment shrimp starts eating your corals than it might be a camel shrimp.
most people get them mixed up because they look alike, google camel shrimp or hing-beaked shrimp, then googl epepperment shrimp, easy to tell the difference if you know what both look like
