I thought for sure I was losing this particular coral because it was getting some receding tissue in a pretty decent sized area. I moved it off of the sand and put it on a pile of rubble. Did this about the same time as adding some more lighting. Been about 1 1/2 months since then it now it's got six small plates growing off of the exposed skeleton. Anyways, I'm not even sure if it's a big deal or not but I'm proud of it. Here's some pics.
