Hey people was wondering if anyone out there with discus had encountered small white spots on the fins and tail of their fish before? These weren't there before and are about the size of a grain of sand. I have had my tank for about a month and have brought my fish from 4 diffrent aquariums in our area. I have 5 fish and have only just noticed these spots in the last couple of days. Any info would be greatly apprecited (by me and my fish!) Thanks
