Hello, I introduced a pleco into the tank about two weeks ago. Everything has been running smoothly. But, I just looked at my tank and the polleni isn't moving, seems to have an almost white film covering him with little dots and glazed eyes. The pleco also appears to have white dots on it, but is moving. I have had the polleni for four years in a 90 gallon tank 2 of them by himself. If its ick what should I do to treat it?! I've never had this issue before!
