As a general rule of thumb if it can fit in the mouth it is lunch, but Oscars raised with other tank mates can be tolerant of those tank mates. Generally, if the aforementioned is followed, the Oscar is at more risk of being bullied than the other fish. Let him be the largest and/or most established and you have a coin flip on other tank mates.

My experience is they are actually a peaceful fish. Just have an "aggressive" if that's what you want to call it feeding response. There big eaters! But if you have a large enough tank you could have most any peaceful fish with an oscar!
