zoos arent more advanced they are actually easier to secure than mushrooms. but they are toxic, I reccomend gloves (powder free)and saftey glasses, (yes I use them) zoos all you do is get a butter knife and lift one edge of the mat then peel it until you get as many as you want then cut the connecting tissue with a razor, pat a piece of LR dry add a smear of superglue gel about the size of the mat then pat the zoo dry on the bottom only and stick it down to the glue, it sets almost instantly, dont feel rushed they can stay out of the water for a goodly amount of time, then rinse both the original colony and the new frag in a little bucket of tank water to rinse off any pollution (from the cut) and place in your frag tank.
