My Green polyp Toadstool hasn't been doing good for about a week.
While putting in my corals last night...I saw what look like a sponge on the stem of it.....until I touched it:dead1:
I have the same crab. Last night I watched him saw a piece off my toadstool leather and then run away with it. He's been doing it for ages, and I have been blaming it on the poor emerald crab. When I moved the toadstool, he took a chunk out of my yellow leather :-( I am going to have to get another toadstool to keep him happy.
