I also noticed this. My safecrackers, rpe, radioactive dragon eyes, dragon eyes, and my eagle eyes of been closed up since last week, some of them are open. But I can tell that something has been eating them from the base of the polyps. I checked last night, and the zoanthids were covered with medium-large pods. I am thinking of adding a Mandarin goby and a Leopard wrasse to solve this problem.
