My dad has owned Oscars before. He would buy a few every year and throw them in his pond. And CRAP did thoes fish get BIG! LOL In my opinion(since i own a 30 gal. salt and 150 gal. african chiclid tank) I would look in to buying a different type of fish, unless you own a pond, but if you want a large fish i suggest buying some goldfish they can get to a decent size, even though they are usually sold tiny. If you want an albino fish, i currently own an african chiclid albino he is about 4 inches long (but i feel bad for him because all the other fish ignore him)
