Get her in a lower lighted area and low flow and see how see's doing I would cut off all the dead skeleton there could be toxins in the skeleton,plus it takes less energy for the coral to build new skeletor.
Yes that exactly why. chalice do not acclimate well to high light. they will recede and die quick if they aren't use to it. shade and low flow. Once its there don't touch it. Moving stresses it too.
Okay I see . I'm not very experience chalice . The only reason I have it's because it was givin to me as a gift . Now I know for the future . Thanks a lot .
