humane way to kill fish

[Reefer Rob]

There's no way to know what a fish feels as it freezes. They're cold blooded, and they only have a primitive fish brain. They most likely don't feel a thing, or even understand what cold is, given the constantly warm environment they normally live in. I'm not sure there have been any studies of a fishes reactions to freezing.

I think the question Nats should have asked is how do I put this fish down and still feel OK about myself. Taking a fish I've had for 3 or 4 years and smashing it with a brick when it gets old and sick isn't going to work for me.
