Maybe we need a well researched documented article about this subject
Oh, absolutely agreed! Hey...lets get started on the article, eh?

I just did a google search on it and found one or two references that said something to the effect "according to the American Veterinary Assosiation freezing is not painless~" but theres no reference to it and I think someone just dreamt that up.
Heres one of the best links I found:
Linkwow! thanks for that link! Very informative!
What I've read (on this site) is that freezing them will freeze the blood and turn it into sharp little crystals, or something to that effect. Which does sound very painful.
Yes, I have heard this, too...but Clint brought it to our attention that fish are infact cold blooded, so therefore, they just slip away. I also doubt that blood freezes in the fashion as it it thicker than water. I have used the clove oil method a couple of days ago, but the fish was already listless.
Icecube method all the way!
hey LFD...try a little salt in his water 1 teaspoon per gallon (rock/aquarium salt dissolved before you put him in the bowl) It's known to perk up a betta!
