Half of candy cane going downhill

[JoJosReef]

For a few days now, half of this candy cane has been looking very bad. First deflated, and now looks like tissue is peeling away. Oddly enough, this candy cane is "hosting" the clowns, particularly the female who likes to love up on it. But for a couple months didn't seem like the candy cane minded.

Is it possible that the pink nepthea is stinging it? Its branches can extend a bit at times. Or maybe the toadstool (can't tough each other, but it's nearby)?

Testing still pending for today. Will post parameters later. Thanks!

Typically your best bet is to frag off the dying heads and remove them from the display to avoid infecting the healthy heads
