Hello I saw a strawberry crab at the lfs today and I wanted to know if he would be a problem in my saltwater reef. My current stock is one Bengai cardinal, one brown dragonet, misc mushrooms, Xenia, Kenya tree, hermit crabs, brittle stars, peppermint shrimp, and a couple corals I can't remember the names of. Would he hurt my coral or inverts? The crab is on hold at the store but not paid for so we will see if I can get him lol.
