Hi, I noticed yesterday that my mandarin goby has discoloring spots on his fins. I checked my PH, Nirite, Nitrate and Ammonia levels and all of them are normal. The only thing i did different the last couple of days was the lights weren't on for 2 days and i just started to add Strontium and Molybdenum. Any help will be greatly appericiated. Thanks,
