Is this Aiptasia on my Zoa's?

[FrankAbagnale]

I just saw this today and I'm not sure if it's aiptasia or not. Could anyone help me with identification?

A fish swam right over it and it sucked itself into the white tube. The Tube wraps around the little rock that these zoa's are on. I haven't seen this anywhere else in the tank and I definitely didn't see this yesterday on my zoa.

After doing more research I think it's a feather duster of sorts. Can anyone confirm this?

That actually looks more like a vermetid snail. If you see white 'strings' coming out of it, it is a vermetid snail.

I'm not sure its a vermetid snail. Doesn't seem to look like other pictures I've looked at.
