My mushroom was on a piece of rock from which it escaped. It had seemed happy for a long time in its location, but seperated itself once and now did so again. The first time I reglued it there was a piece of the rock on it, so i was able to glue rock to rock. But its latest escape seems to have resulted in complete escape from any rock. This morning I have found it in three places, once on a coral that would likely sting it. What do I do?
