If your mushrooms are leting go of the rocks, that is the way they move around if they don't like where they are placed. It could be to much or not enough light, some other coral could be stinging them, or your levels could be all crazy. mushrooms seem to like an aquarium that is nutrient rich so to much skimming could be a problem. Try moving them closer or farther from the light to see if they stop getting loose.
