    ID black stuff???

    I recently purchased some mushroom frags. between the two mushrooms there was this black mushroom-like substance growing on the rock. It has since grown. Any ideas as to what it could be?

    I've had forms of this stuff growing in my tank. I still don't know what it was, but I don't think it caused any harm to my tank. Mine were more of a white or grey color, but they looked exactly the same. My theory is the stuff is a "home" for a copepod or something, but I'm probably wrong. Anyway, I know I havent helped much, but I just wanted to let you know that you're not alone.
