so I have been doing daily water changes (over 70%) now for over a week and my nitrates are below 5 all the time now, mostly looks to be 0. The spot is not getting deeper or bigger or changing at all. He is still active as ever and eating great. Shows great coloration and continues to act normal.
Maybe it will take months? I don't know if this is hith or not but with how I maintain his tank I highly doubt it was due to water quality or diet. No stress, idea temps, quality food, ect ect.
Help me out here... what could it be? how does a spot exist for months and not change in anyway?
he gets veggies in his diet too. unless he is in the light you can hardly notice it exists.
