Hitchhikers ID

Hi guys, I'm hoping for a couple more IDs on hitchhikers that have appeared in my fishes domicile!
The first is a transparent pinky white tentacle like thing. It looks to be attached to the rock and has been growing.
The second is a small tube attached to one rock with a spiral at the bottom and what looks to be an opening at the top. (May be a vermetid!?)

Any help greatly appreciated.
