I think I read that a single Oscar could be kept in a 55 but a pair would be better in a 75 gallon. They put out a lot of waste like goldfish so you need good filtration and large water changes on a regular basis. I personally enjoy my large goldfish as they are easy to keep compared to sensitive tropicals.
I haven't kept oscars either as I read they can be troublemakers when bored, and are known to break heaters and ransack the tank decorations.

I wasn't very pleased.I think I read that a single Oscar could be kept in a 55 but a pair would be better in a 75 gallon.
