I've had this colony for about 2.5 weeks. It was drip acclimated and dipped in Bayer. Initially, everyone was open and happy, but over the past week or so, a couple of areas have started closing during the day, nd some are half open. I can't see any obvious growths, spots, etc on them, but the closed areas seem to be spreading. I removed and dipped 3 days ago in CoralRx. Is there any way to diagnose what might be going on here?
