I have a Pacu, named Caesar. When I first got him he was the most shy and scared fish in the tank, always hiding. He would never come out for food, the other fish always got there and ate it all. He was too scared to move from his hiding spot except to pick around at night, which isn't enough to stay healthy.

I would feed him separately and once he got more confident, I was happy. Now he's very confident. Too confident. He's become the boss of the tank since my Oscar died trying to eat something way too big for him, like the cocky jerk he was.

And the teeth.

Those teeth.

I couldn't see them when he was small but Pacu have HUMAN TEETH. All Pacu have teeth like that, but not this prominent. You can't see them unless you really look in the mouth. His stick out past his lips. I'm afraid he's going to kill me with those blunt human fishteeth one day, revenge for making fun of him when he was small for being the biggest fish and getting bossed around. He could jump out and EAT MY HAND when he gets big.

So I treat him as well as I can, pay more attention to the tank now than I ever have.
