Depending on the size of the shroom you are fragging you can get two or 4 frags out of it, you cut straight across, like a pie, be sure to get at least a small piece of the mouth in each section, then place them in a small bowl on top of some ruble rock and seal it off with a piece of bridal vale secured with a rubber band and throw that in your frag tank, or the corner of your aquarium, the shrooms will attach to the rubble within a couple weeks at the most, then can be glued to larger pieces of rock, kind of a quick description but hopefully this helps to give you a better idea, also don't panic a shroom will do fine out of water for around 15 minutes, but the slime makes it a pain to handle lol!!
