I recently got a piece of cats paw coral, and for the first week or two it was doing fine. Now it seems to be bleaching. The weird thing is that I still have polyp extension. None of my other SPS are showing any signs of problems. From what I read cat paws like a lot of light, so it is higher up in my tank (started lower down and was moved). Any thoughts on what could be happening? I plan on doing a water change tomorrow, but aside from that I am baffled. The fact that I still have polyp extension is just really weird to me.
