Is it impossible to frag zoas too small? I found a polyp which was sort of cut on my red zoas, so I cut it the rest of the way off and glued it to a plug. It looked great on day one. Day two it was sort of leaning but still open, and day 3 it popped off the plug and disappeared. I was thinking of seriously fragging a giant barnacle I have covered in gorilla nipples and now I'm afraid the same will happen there. Do you think it was because it was just one polyp and there was no mat with it? I'm afraid I will kill my whole colony if I go at them with my scalpel. Also, did I skip a step? Does anyone use betadine or iodine?
