yeah...well anyway, the oscar had the affliction when I got him- rescued from some idiot who dumped him at petco- seemed to get better when I fed him High-dollar japanese cichlid food, but it almost looks worse now. My 1st instinct was to do a h20 change, which I did (30%)-it's my wife's tank, so I am trying to guide her gently- 8 mo pregnant wives do not like you telling them what to do so I GENTLY suggested a water change...we'll see...
