I bought 4 zoa frags about a week ago. I dipped and acclimated the zoas and placed them at the bottom of the tank. The next day all of them opened up and looked fine. About two days later one of the frags started to close up. Each day one polyp would close up (It only had three polyps) and eventually all the polyps closed up. The other three frags are open and doing great, its just that one frag that is closed up. I do have other zoas in the tank and they are open and doing great too. What could the problem be?
