I have been fragging a few of my zoa's as of late. I have noticed that fragging a single zoa polyp vs fragging say a half dozen polyps into the same frag seems to make a huge difference in there ability to spread on there own. One just seems to take so long to have the ability to make another. where as a small colony cranks out another polyp every few days.. anyone else had this experience ? is there a magic number of polyps per frag for better success
