Decorator crab Dilemma

[Jmulgrew97]

SO I just recently put a decorator aka camouflage crab into my tank and have a concerning question.. I have 3 small coralline snails, along with 1 turbo snail and the decorator is known to kill inverts to stack on its shell, should I be concerned for my snails?
