for my frags, i reach in the tank with some scisors. get it while its fully open. take off what you want with a fast clean cut.
get a small peice of rock or whatever you want it to grow on, pull the frag out of the water, dry off the base, put some super glue on it, stick it to the rock and place it in a low flow area for a while so it can attach to the rock. my leather frag is slowly attaching to its LR rubble piece. its been 2 weeks i think, almost!
