vermetid Snails any predators?

I have a vermetid snail infestation. Only problem I have with them is they are all over and it hurts when it stabs you when you grab the rocks they are on. As far as I know they are not harmful but they string out nets into the water when sand was in the water, and grow on my lps which I can break off their tubes but they keep growing on everything. Is their any natural predator to them? I cant scrub them off or use super glue because of the amount of them.

 

I would ask john maloney, he is the snail expert
