I completely Agree, Zoas close up time to time. The one parameter that I would check though is your ALK. Usually sensitive zoas closing and loosing mass are the first sign of an ALK spike. The inevitable truth is that from time to time colonies melt away, even the best of us cant stop that. Good luck with the zoas though looks like you have some nice pieces.
