Any idea what this thing is? I just noticed it growing on a small piece of rock at the bottom of my tank. I see something similar growing on and around one of my pizza polyps as well. I can't tell if they are the same thing. It's pink around the outer portion where the clear things are coming out of and white in the middle. It looks like it might have a mouth in the middle but it's really small, almost the size of a dime. It hasn't moved since I noticed it.
