Don't release your pets. Ever. Most likely, they will die horribly. If they survive and find others to reproduce with, then you've got a breeding population which is not endemic to the area and has high potential to cause damage to the ecosystem.

>Far from being an innocuous domestic animal, a goldfish freed in fresh water is an invasive species, an organism that is introduced to an environment, can quickly reproduce, outcompete native species and destroy a habitat. And even though they get less attention than invasive organisms such as Asian carp or zebra mussels, goldfish appear to be a growing problem in bodies of water across the United States and around the world, triggering warnings from government officials in Virginia, Washington state, Australia, Canada and elsewhere.

>Also known by the scientific name Carassius auratus, goldfish can live to be 25 years old, weigh as much as four pounds and measure well over a foot long. They’re also surprisingly resilient: They can survive in severe conditions and can weather winters in bodies of water that have frozen over, living for months without oxygen. This quality, Bajer said, “makes them really, really tough and allows them to dominate certain types of ecosystems.”

Eh, I get that they're generally tough but mine got sick after a water temperature change so... uh...

Let's start eating it then. That will solve the problem. :D

Wild-fed ones might even be tasty. I've had some decent carp before.

I have some really tasty carp recipes :)

I like to eat random fishes and Carp has been one of the hardest to figure out how to accent correctly. It has lots of bones and the flavor of really "in the dirt" catfish. So far Fish Sauce, Cumin, Curry and a few other things really work well. Also kinda have to cook it slow so everything absorbs.

Is this linking to the actual article or to a pricing page, I don't understand.
