I can't get a good picture of them but, I was adding some more rock today and I put my GSP in with the side that is normally at the back facing forward. There are small bright yellow clumps scattered on it. They appear to be porous, could this be sponges I haven't heard of anything else that fits that description. hoopsdaddy did you have any sponges in your tank? I will try to get a photo and post it.
