Oscars are not too bad they get to be a foot, I have bred them before. Arrowana's get to 3' and like to jump. I know people that had to keep bricks on the cover just to keep them in a tank. If I lived someplace warmer I would love to have a couple of them in a pond.clifish It also amazes me people buy oscars anymore, but they do. That Pacu is about ad vegitarian as you or I are. Pretty sure he just had to adapt to survive. We sell quite a few arrowana and things also that get big. I just make sure to warn people they get huge.
I aslo don't undestand why stores sell 3" SA red tail cats, they get 6'+
