Coral identifacation

[Jack Sparrow]

Hi I'm thinking of purchasing a coral from my local pet shop, but I'm not sure what species is and they don't know either. It looks to me like this species are rhodactis mushroom I would really like to get it but I'm afraid it would eat fish like a elephant ear. The one in the store had clown fish swimming through it and a cleaner shrimp beneath it but I am still afraid it will eat fish if I put it in my tank. Can any of you identify this Coral, is it safe to put it in my tank without it getting my fish or should I avoid it

Looks to be rhodactis. If your worried about fish I'd avoid it. Many corals big enough can be fish eaters but personally I've never had an issue with large mushrooms.
