if you want to frag them, use a sharp razor or exacto knife to cut down to the base, and then u could use a sharp wood chisel to peel the layer of rock off and easily reglue to another rock or plug

wood chisel believ it or not work great for shaving underneath zoa's and xenias, mushrooms and leaving a solid part u can superglue to another rock or plug

side note, wear gloves/goggles always when fragging, all corals, not just zo's have potentially toxic chemicals that could get in a cut/eyes/mouth and make u pretty sick....

I have done a ton of fragging, and learned the hard way (even with xenia)
