Can Anyone ID This Coral?

[mtbikedr]

Hello All,
I got this about 3 months ago for a pretty cheap price, and because I thought it looked cool, it has a bell shape, and my damsels use it as a cave. It had a few bare patches on it, and it now looks to be growing. It feeds voraciously when I add most anything to the water. I keep it high in my tank and have PC lighting. Tonight I noticed that it is taking a cool green coloration, and it appears to be budding new lobes towards the upper side. Can anyone identify this coral?

Hey all, thank you for your replys. I was at the LFS where I bought the coral, and they told me it was Merilina. It's growing very well, and looks cool.

A little tough to tell but I agree either Merulina or possibly a variety of Pavona
