i once saw a 12" oscar in a 5 gallon fish bowl no filtration the lady keep it in her kitchen and every day she would empty the bowl and refill it i was not into fish keeping at the time so i thought it was funny knowing what i know now i have no clue how this fish survived
oscars are big pretty fish that like to swim they cant really do that as adults in a 55
i think if you keep a oscar for about a year (time to reach 12") you will want to get a larger tank for it

The tank alone would be 12" so there would be no way for the Oscar to move at all.
