I fragged my devil's armor a couple of weeks ago to trade for some new stuff. I had only had it for 2 months, but it had already grown to about triple the polyps that it had when I got it and was growing off the frag rock onto my rock. I just took a new razor blade and cut the original frag away from the 3 polyps or so that were on my live rock. Since then the polyps got smaller and now there is only one left that opens. Did I kill off my zoas? I thought that cutting the mat between polyps would have been safe.
