i recently purchased some clay zoas, about 60-80 polyps worth. Acclimated them for about 1 hour, and put them in my 24 gallon nano reef. For some reason, they won't open, and haven't opened since i purchased them. I dose the tank with Kent Microvert every two days in order to keep my carnation coral healthy. All my shrooms are doing amazing, as well as the fish and the carnation coral, but for some reason these zoas seem extremly unhealthy. As far as feeding goes, microvert is the only thing i use. other then that, they rely on the light. They are placed at medium height in the tank, directly under the light. Any help would be great!
