SO i just got some new frags and they are attached to plugs. The plug has the disc the coral sits on then the "plug" part that sticks out. These are ceramic. I wanted to remove the plug part and just leave the disc and coral remaining so that i can attach them to my live rock smoothly. I tried cutting the plug part of with a baby hack saw and that is not working. I am in the middle of doing this so any fast help would be great. How can i get the plugs removed so i can put the coral as close to flush on the rocks as possible? Thank you!
