I had an SPS coral come unglued from a rock and fell on top of one of my soft corals below. It looked fine when I pulled it up 2 days ago, but now looking at it, appears some branches are dying. What is the best way to treat the coral? Should I clip off the dying branches to keep it from spreading? Should I frag some of the good branches as it might have already spread to the base? Should I leave it alone, and hopefully it pulls through?
