I've got a rock that is overflowing with mushrooms and I'd like to get a lot of them off. I'm thinking it's a lot like an anemone where you just have to lightly peel the foot off the rock. Then it's just a matter of getting it to attach to a frag plug. Am I correct in this thinking? If not, how should I go about fragging them? The tank is a "little" dirty in this pic. It's a process to bring it back after you let it go for a month.
