I've noticed that receiving fresh cut zoanthids seems to have about a 50/50 chance of making it, I also always dip all corals to ensure I don't get any unwanted pests. I know if I scrape some of the frag plug with the zoa/paly success is much higher than actually cutting the polyp at the base, I have about a 80% success rate when fragging my own stuff. I usually do an iodine dip after I frag to ensure I avoid the dreaded white fungus. Is there really any trick to a higher success rate when receiving freshly cut frags? Of course some species frag easily and others are a little more sensitive.
