I just read an article that suggested a humane way to euthanise a fish is by <<<<<<placing the fish in a small container with water and adding an Alka Selzer tablet>>>>>> Has anyone ever heard of this and/or done this? I assume I will at some time in the future, have a need to know how to euthanise a fish, and I know I won't be able to do it by cutting its spinal cord. Thanks. Gitte
