Your Oscar look rugid. Like it's ready for the wilderness lol. Pretty cool. Oscars have such great personalities. I use to be able to get mine to eat food fight from my fingers.
I didn't need to teach my Oscar that one lol. Mine had scared the crud out of me one day during feeding time. I would dip my fingers in the tank with the pellet and he would swim up get it and dart back down. Well apparently I was going to slow because I got another piece and I had my hand like half a foot from the water line well he jumped got my finger was only and inch off his mark from getting the pellet. I dropped the pellet and he got his meal. Although this was neat I tried not to incourage my Oscar to jump. This is a fish with the potential to get 14" in length and a small fish out on the floor is easy to pick up and put in the tank. A big fish misjudging its target and landing on the floor is harder to deal with and harder to pick up. So caution is advised when making your new guy jump.
