Vermetid Snails Bad?

[ISFNick]

Are Vertmetid Snails bad for my tank?
I have a boatload of them all over my rock.
Can they harm coral?

They just irritate them so they dont fully extend

I break them off when I get the chance, or super glue the hole closed

I have a lot of them. They mostly just irritate frags but don’t seem to bother my colonies. They just look bad.
