Would like an ID on this hitchhiker

Just set my tank up on Monday and found these growing from my Live rock.

Hard to tell from the blurry second pic, but I'm guessing a mushroom coral (Actinodiscus sp).

Thanks..I should have given more detail since the photo isn't the best,,,mostly dark green with lite green/white spots (4x) symmetrically around the circumference.
Th first picture got messed up when I had to reduce it's size to fit the posting. but if you look closely you will see what I think are aiptasia (6x)..goiing out and getting a peppermint shrimp today to see if he takes care of them for me. Kinda sucks to have something growing that is relatively pretty and have to get rid of It.
