I found a bunch of these in my tank and they were eating my birdnest.

Limpets, but are you sure they were eating the coral and not just cleaning up necrotic tissue? Dying corals will attract all manner of animal that wouldn't normally attack a healthy specimen.

They almost have like a mushroom like body that covers the coral. I have a bunch of them in my tank from my live rock. Just wanted to make sure they were not super dangerous thanks
