I recently purchased a small mushroom from my LFS. It was laying on their sand bed. When I got it home I noticed a very large Aiptasia Hiding in one of the large hole in the rock frag. I couldn't get to it with anything so I chipped appart the rock with the Aiptasia andquickly placed the mushroom back in the tank. It spent no more than 15 sec out of the water. When I placed the mushroom back in the water it let off what looked like a sperm cloud? Did I damage the mushroom, what happened here?
