My Oscar has a blotch on her that can only be seen when lights are on. Is this something I need to worry about? Parameters are 0 ammonia, 0 nitrites, 20-40ppm nitrates. Water changes 50% 2xwkly & She's in a 90gal cycled by herself. She's fed market shrimp, peas, hikari cichlid pellets & super worms. Any advice is welcome. Thanks!!!!!
