Jack used to get in his tank with his pacu and other fish.Lawd almighy. He's a beast. Damned if I'd jump in. I've had bites in my arm just cleaning the tank. lol. Ever seen the episode of River Monsters entitled The Ball Cutter? Let's just say keep the ole family jewels outta the river. This guy has my paccy beat by about 4 or 5 inches and all the girth that comes with it. Definitely impressive.
