if thers is enough to go around, i could always use more zoanthids,
fragging is easier then you think....
there are a ton of warnings and stuff so i would suggest eye protection and gloves. then its really just breaking the rock where you want it so that you can glue the rock down to the frag rather then the zoanthid. and cutting the mother colony is simple, just try to damage as little as possible and use a clean razor with absolutely no rust.
im sure more will give you a better idea of how to do it, maybe even a pic post.
just my 2.5 cents
