There's nothing wrong with eating your fish. And, like Delta said, you COULD go buy a tank, but then again, there's that one little obsticale; money. Not everyone has $450.00 to buy a tank online, not to mention the shipping charges on that. There's going to be very few local sources that'd be willing to accept your fish, especially a pacu. I stand firm in justifying that you can, in fact, eat your own aquarium fish. How is eating your own aquarium fish any different than eating a cow you've raised that's been standing in it's own excrement out in a field?
