I hate to be the one to say this ,but I will. Why in the world would it be good to have snakeheads thriving in rivers in the States. It is attitudes like that, that get the fish banned in the first place. All those people wanting to keep snakeheads will soon not be able to because of a few knuckleheads who could not keep them in their tanks released them into the wild. Not to mention the damage they do to the native wildlife stock that has no natural defence to these fish. In Australia there has been millons of dollars damage ,and not to mention native speices that have become extinct,( that right never to be seen in this world again) that has been done by introducing foreign speices into the wild. Also because of this fact there are a lot of fish that cannot be bought b/c of the fact that people can't be trusted not to release them into rivers and dams. Just goes to show the mentality of some of you people, ever heard the the expresion " To cut off your nose to spite your face", this is a perfect example. Why don't you people sit back and actualy think about what you are saying for a second.
