I rescued the oscar from a friend of mines tank who has been the hospital and couldn't take care of her fish anymore. But, anyways, it already had the infection. It lost a part of it outer skin and had a fungus growing on it. I had it in a hospital tank with victoria green and acriflavine. As for your oscars eye coloured, there are more top half blue bottom have orange.
Hopefully it is just the way that his are really are. And Thanks for the advice. I got him out of the medication so hopefully he is fine.
