You own a oscar now?Black? Maybe blue? I wouldn't bother as much with prepared ornaments, but maybe some rock or wood? I'd say a definite no to live plants as they would be very hard to maintain in an Oscar tank, but if you're wanting some artificial plants then you might be able to get away with a few.
Not so sure about lemon Oscar, but maybe a lutino. I'm pretty sure they're not albinos.
