Identification trouble (×2)

[KcAQUARIUMS]

Really need help identifying these organisms, I tried to take the best pictures I could. The first thing is attached directly to an astrea snail, it looks like an anenome of some sort, and shoots itself back into the crevice of the shell if it is startled or I turn the lights. It's really something to see because you wouldn't think it would know but sure as hell it reacts to my hand waving etc. The second came on a price of liverock, looks almost like a mushroom you would see on a rotten tree outside, not sure if it could actually be just a mushroom but I guess that's why I need some help lol. Ask questions if you need to because I'm completely stumped!

The first picture looks like a feather duster to me. Most nems, in my experience, aren't that reactive to light.

So what is a feather duster? And will it get bigger and harass the snail? Spout more heads? If you could give me more info that would be great still kinda new

They're filter feeders. They're good to have around. Here's a link to @Lionfish Lair 's page on them: http://www.lionfishlair.com/hitchhikers-guide/serpula/ Snails tend to become hosts for a wide variety of non-motile hitchhikers like vermetid snails and feather dusters. I haven't noticed them particularly bothered by them.

Sweet thank you. Very good info and a great help. And idea about the bottom pics?

I can't tell what's in the second picture. Can you get a clearer shot?
