Get small cuticle scissors or a scalpel and remove the mushrooms. You can cut up the mushroom fairly well and rubber band it to a rock once you get it loose. The zoos are harder to mount after cutting.
Crazy Glue it? Maybe i could put it into a breeder tank which has live sand and then when the sand gets attached to the mushroom then just crazy glue it to a rock what do you guys think of this idea since i have pretty strong water circulation in my tank.
