You can do it in the traditional manner. (before you do so make sure that you are using clean equipment) Clip the gorgonian to the size you want, with wire strippers take off about a quarter inch of flesh off the clipping, then attach to the frag plug with crazy glue. Some will glue the clippings without removing the flesh. When you remove the flesh, target feed the polyps directly above the area, and the stripped section should recover very quickly.
