I have to say I'm pretty disappointed in this forum right now.
I recently worked a job as a park naturalist in Northern Virginia and had only read bits about the snakehead before starting the job. The park was on the Potomac River and the snakehead population exploded over the few years I was there. It went from fishermen at the boat launch joking that there was monster fish out there to a couple of years later catching them every time and not catching any of the fish they wanted. I've hacked countless snakeheads in half after fishermen brought them back to the dock.
Point is no matter how careful one or two members of this forum would be it is not something to discuss. All it takes is one of you putting a video of it feeding on YouTube to convince 100 public idiots that they should get one too, and then just a couple of those getting tired of them and letting them go.
You shopping around and asking for them tells less reputable lfs that there is a market for them so they should order a few and see if they sell. You might take care of and never release yours, but most won't.
You can roll your eyes all you want but this is real and it is happening and a responsible owner forum like this should be doing everything it can to stop this problem.
