Zoa ID please! =)

I have a piece of live rock a guy gave me that was covered with coralline algae to help get it started in my tank. I had the rock for three months and all of a sudden I noticed some small polyps. After about three weeks I was able to tell the colors but don't know what type it is. It has a purple mouth with a bright neon green ring around it with a brown skirt. Any ideas? I can post a pic if needed!

Just realized there is a thread for id. sorry. How do I move my thread?
