Help I think I may of killed my Coral frag

I bought the one in the far back about a week ago. To be honest I forgot what it was called, and it came with a elastic on a rock. The rock turned out had a aptisia, not sure if I spelled that right, so I took it and attached it to another rock at the stalk like root base. That started turning black. So I inspected it, and the frag broke off. I panicked and put it in a hole where it is now. What do I do.......?

Looks like a shrunken up softie of some kind, it's still alive but not happy. If it's sitting in a hole on its own I would just leave it alone and hopefully it'll start opening up and eventually attach its self to the rock.

Yeah no it's totally not happy. Looks like someone who bought tickets to what he thought was a Bruce Springsteen concert to find out it was actually Nickleback. The frags in the middle of my tank now with a Radeon light. I hope I don't have it to high up. It was the best hole I could fit it in
