some type of galaxea or flowerpot?
regardless, it probably won't do well at the bottom of your tank unless you have really good lights. can you get a closer pic?
Thanks for the help, I can't really get a better picture, the camera sucks. But there are actually dozens of little tentacles on it, and they have gotten longer since I took that picture.

Well I've looked up both the galaxea and flowerpot corals and after staring up close to what's on my rock I think it's a brownish/orange galaxea coral.
Thanks to everyone for their help
