I was wondering if anyone has ever had any problems with a little redish-brown color organism in your tank. I have these guys in my tank and I don't have any idea what they are. They started off in the sand and now I see them on the glass. They are about as big as a grain of rice and sort of transparent. They don't seem to be harming anything at all. Just wondering what they may be. Thank for your help, Roy
