A while back I bought this cool looking live rock with a coral skeleton on it. I thought it would be a pretty backdrop for some zoas, but I put it in my tank, then forgot about it for a while. And now, it's not a dead skeleton, it's a live coral........but what is it?


It's very pretty, and growing quite nicely. The rock is about three inches by five inches, if that helps. The centers are bright green, surrounded by a dark purple with white stripes running through it radiating outward.

Anybody know what it is?
