Ok, I don't have any pictures for you, or even much of a description, but I hope you can help anyway!
I've got one rock in my tank that's absolutely riddled with holes. They go way back (inches) into the rock. If I shine a light up in them, they are buzzing with pods, and occasionally I'll spot part of a bristle worm in there.
Today, my wife was watching the tank feed, when she started freaking out and asking "what the heck is that?????"
I got over to the tank just in time to see one of those holes in the rock expelling some nasty looking white slimy poo. A lot of it. Like maybe 1/2 a teaspoon! It was a thick liquid, and flowed down the face of the rock and dripped off the bottom into the water column. Of course, my clown had to snatch a mouthful.
Who's poo?
