Dead colt coral...now what?

[MikeP]

I bought a piece of LR from another canreefer. It has a colt coral on that was not doing well. I've tried to revive it with no luck. I am about to give up what should I do with it? How do I get it off the rock? I've tried to attach a pic. If you think it can be saved please tell me how. It has looked like this since I bought it just over a week ago.

Thanks
