A Magician Zoa I had bought at the BAYMAC was doing great in my tank until a few days ago. All the polyps on the frag were shriveled and spitting out their guts (that grey stuff that looks like piles of worms.) I'm not sure why because all the water parameters were fine and everything else in the tank looked in top shape. What could have been some of the reasons this happened so I can't prevent it from happening next time I add corals like that?
Thanks!
