What do you mean it's column was ripped up? Are you talking about a single zoo?
To frag zoo's, you need to cut underneath the individual polyps hopefully getting the entire polyp off the rock. Then use super glue gel to glue the bottom of the zoo mat to another rock. Be sure to dry the rock and zoo's as best you can. They can stay out of the water for a long time so don't worry much about that. I've never used gloves, but they don't bother me. I could be mistaken, but I believe that if you're not using gloves to put them in the tank in the first place and you have no reaction to them then there is nothing to worry about. If you have dogs and/or cats you'll want to keep them away because eating a zoanthid or some of it's toxins has been known to kill small animals like that.
