right now i kind of have it sandwiched between two rocks because the rubberband kept cutting it in half, so now i have about six frags off of one coral. all seem to be doing well though. the sandwich consists of rock,colt,rock and then rubberbanded so the rocks cant move and the colt cant come out. the rubberband is wrapped around the rocks and not the colt so it cant split it again. what do you think of this??
