featherduster, or some kind of apitasia?

[manse]

These were "inside" a bunch of zoos I bought from an LFS. There were two cute little snails that came with the coral. Then I started noticing the zoos were getting eaten! Snails are gone, but before they left the cleared away some of the polyps to reveal this (long white flowey things in center of pic):

 

 

 

 

My first thought is that it is some kind of featherduster? The picture doesn't really show their long trunks well.

 

Any ideas?

I don't think it's a feather duster.

I've seen them before, and wondered the same thing. I believe thye are some sort of filter feeding worm, but have no way of proving that. I do know that they did no harm and did not spread in the tank I saw them in.

 

just my $.02

Do the "tentacles" come out of a hard tube?

 

Doesn't look like aiptasia, unless it was purely bleached aiptasia, but I'd guess no. Not your regular mini featherduster either.

You mean hydriod?
