Some kind of polyp? (pics)

[Gatorfreak]

This little cluster came on a tiny piece of rock that came with some zoos I bought. Maybe they are zoos but I've never seen any with such long "trunks". Sorry the pic isn't very good but maybe someone can give me a clue?
[edit]I just got them so I'm assuming they open up with something but I haven't had it long enough to find out.[/edit]

Looks like Isaurus tuberculatus . I'll see if I can find some info and pics for you.
