I recently added a starfish (posted in Invert section for ID), as the LFS said it would be no problem with the reef. Well, this morning I saw it on top of the red mushroom frag I also got from the LFS. I got it off, but the mushroom had spit it's white stringy guts out, and it looks like there is a small dark spot on one side. Do you think the star was eating it, or was it just a case of the mushroom getting irritated at being sat on?
