A friend recently purchased some live rock and found a snail hitchhiker Cypreas Tigris. He is asking me if I would like it for my carpet anemone tank. When I read online I find that the snail can eat some anemones and soft corals. I don’t mind putting it in with my carpet as long as he stays away from the carpet and the carpet stays away from him. Is this a carpet anatomy predator? Or more a threat to BTAs etc? Also can I house multiple carpets together and even BTAS with a carpet (separate question).
