Vermitid snails?

[Wolf89]

Are these vermitid snails? I just got this frag rock from a frag swap and I'm wondering what these? If do, what do I do? I'm doing a peroxide dip to get rid of green hair algae, will that get rid of them? I'm talking about that white squiggly thing, it looks hard. Thanks

They look like tube worms/feather dusters. Harmless

Doesnt look like vermatid to me, the tubes I have thay look like that are little feather dusters.
