Whats on my snails?

I took one picture, but all my snails have this black crusty thing on their shells.

Hard to see, possibly a vermetid worm

I just have my phone for pictures... took one of the dudes out.

Those were the best pictures I could get

Looks like a vermetid to me, but it's kinda tough to see the whole thing.

^^^Yup Vermedit snails hitching a ride

Anything to worry about?

Vermited snails feed by secreting a net made of sticky slime which can irritate corals. You can put a little super glue on them to kill them. Just make sure you don't get any on your snail.

Thanks for the help! Looks like I'll battle these guys at the same time I battle the aiptasia!
