Any idea what this starburst looking thing is?

[Mikek]

Hi all, in the three photos below there is a starburst shaped thing in the middle of the photo on my rock. Sorry about the photo quality, had to take the pic at an angle, and the glass reflected. Should I worry? Doesn't seem to be a featherduster, and though I have some zoas nearby, I have only had them a couple of weeks so I don't think it is zoa. It hasn't moved at all yet, so not sure. Any feedback appreciated.

Thanks!

Closest thing I seem to find is a "Chiton", which would seem to be ok, but not sure...

Looks like an anemone of some type. I can't tell on my phone

The photo makes it look bigger than it is, it is smaller than a dime, if that helps.

I still think it's a anemone I just can't see it clearly enough to tell if it's a unfriendly one or not. Most hitchhiking anemones are pests, most but not all

Well I just flashed some light on it in the darkened tank, and it pulled itself in like a worm, which surprised me as it didn't look like something that could retract.

The pic looks kind of blurry but it could well be just the feathers of a tube worm.
