He looks terrible! Very red! The big tank is very clean. I did lwc every week, then one after 5 days, another 5 days later just because he seemed a little less active. I have not fed him since the day before I moved him. I will do daily water changes, Maracyn2 on the hospital tank. I'm not feeding him. I thought I was being so careful and diligent that I was surprised to see him sick again.
