some kind of fether duster?

[Lofus]

I found what looks to be some kind of feather duster in a crevas on my rock. It has brown spiny-like fingers extending from a flat round lime green center. It is really hard to get a picture of due to its lovation.

The fingers don't really move like a featherduster's. It seems more like an urchin's

Any guesses?

Does it look like this only with a green center? It's hard to tell from your description, but it kind of sounded like it could be zooanthids. And, if you haven't already, you can get a lot of help from the hitchhiker faq here: http://www.reefs.org/hhfaq/pages/picture_pages/faq_zooanthids.html

Its probably a green button polyp.

I found a picture of the same thing I have in my tank. I think its a polyp but I don't have much for lighting and I thought that corals need lots of light. I've 2 x 10,000K NO and 1 x actinic NO.
