Couple of ID's

[scelona]

I've got a couple of hitchhikers I would like ID'd, thanks for your help!

Here is the first one, at first I thought it might be aiptasia and got worried but it doesn't have a round base, it's more of a branching structure from a central stem.

The second one is these little guys growing on one of my snails, it was a green tube like base and a little fan coming out of the tip.

first probably macro algae of some sort.. pic is too blurry to tell
from your tube description and fan coming out the top I'd guess the second would be a feather duster worm of some sort again pics are blurry

Thanks for the response, I am far from mastering the tiny in tank shot. Is there any issue with having a feather duster attacked to a snail?
