Does anyone else own one, or more than one of these giants?

I own one tiger oscar, and I can tell you, he has got a HUGE personality to match his huge appetite.
So if you own one, tell me of your experiences, good or bad?
My oscar has this pink pingpong ball that he plays with when I put it in the tank. He refuses to play with ping pong balls of other colors, just the pink one. He can amuse himself for hours on that thing.
Also, he has bonded really well with me (I rescued him, so hes about 5 now), whenever I come through the door he swims really fast to great me. Hes huge now, about a foot long.
I'll post pictures later!
