it its HITH, like everyone else here has said.. step up your waterchange schedule. you should have NO ammonia or nitrItes, and your nitrates should be under 40 ppm. also, dont feed him feeders-there is so much out there that oscars love why even bother giving feeder fish? lol..
waterchanges and a good diet-if an oscar doesnt have these, they will get HITH.
