The freezer is not humane, the fish is still alive and is dying by freezing, I don't know about you, but that seems bad... Clove oil works the best, they don't feel it a long as you go slowly with it. Sakura gave me the link to the site, maybe ask her for it.
I had to get my clove oil at a health place. Heads up, your hands and anything that touches the oil will have the strong scent of clove oil.
Also clove oil floats, you need to add a couple drops to a container, shake it very well then pour it in slowly and you also slowly mix the mixture with your hands so it works it way through their system. It is painless if done in small amounts, it will first make them numb, then knock them out, then peaceful death. Also you need to keep them in the mixture for a whike, because they do get knocked out Amir looks like they are dead. I add some alcohol at the end to make sure that they are in fact dead.
