go to the search button at the top of the page,type in frag video or coral frag.a list of threads will come up,so click on the one that says coral prop video by eric borneman.it is about an hour and 15 minute video and it is awesome.it will answer all you questions.if you cant find the video and still wanna frag,try a loose mushroom if you have one.take a razor blade and cut it straight down the oral disk aka ''mouth'' cutitng it clean in 2.in about a month you will have 2 fully healed mushrooms.hope this helps!
