It’s coral skeleton :) Can leave it on there

If it is getting bigger, it may be more of the coral dying off. How long have you had that coral? Leaving the skeleton won't hurt it any. You may be stressing it more by pulling it out and cutting it off. Sometimes sections will die back. Is there any other coral near it that could be stinging it?

 

[bulzeye]

Thanks guys! No, no other corals are near it. I will keep an eye on it.

How is the light for that coral? In the photo it looks a little low.
