Well, I'm not from Tucson but I used Super Glue Gel making sure the bottom of the frag is bone dry dab a healthy portion of glue to the frag plug or disc or rubble and then slap it on there within a month or so i start popping heads off if they are zoas or taken the edges off if they are monti's as the frags. If i like it enough i will plant a peice on the rock work to let it spread in my tank. If i just want it for fragging purposes it stays on it's plug on the eggcrate.
We have a local guy that makes killer plugs, disc, and 5-6 diffrent kinds of ....um plugs but they are shaped diffrently for diffrent purposes i can't really explain it but they rock and i never purchase from stores anymore i just wait for a meeting and buy 50-60 off him at a wack.
