Club tipped anemone?

[Kizmar]

I just found what appears to be a club tipped anemone on LR. It's only like a 1/4 inch around or smaller, but the tentacles would make it measure maybe half an inch stretched out. It definitely has the "club" tipped-looking arms.

I'm wondering... is there something else this is likely to be (say, a coral instead of an anemone)?

If this IS what it is, is it a bad thing?

I'm waiting for it to open back up, but this is what it looks like closed:

Hard to say when it's closed. I'll wait til I see a pic of it open before I decide. ;)

Here it's mostly open...

Yeah this is the best I can do with my crappy auto-focus camera. No good macro setting on it either.

looks like a ball nem, harmless hitchhiker. I personally really like them

It looks cool, but it's tiny. I wonder how big it'll get?

 

[Bifferwine]

They stay tiny. They are pretty cool and come in all sorts of colors.

They seem to come and go in my tank. Usually in the back behind the rock work.
