Cool, thanks everyone! The mushroom did break off.... and then drift over to my open brain. When I got home the mushroom was laying against the brain and the brain was not happy, but it looks all fine. The mushroom is growing into the sand right now, and I'm going to try and move it back up onto the rock, but it's layed out flat on the sandbed for now and looks happy.
Sadie, that is my serpent starfish in the one picture, not a peanut worm
Thanks again everyone, I really didn't want to lose the mushroom, these things are growing so fast.
Mike, already the mushroom left behind after the big polyp dropped off is already forming two new mushrooms!
