Oh No I feel terrible, for a fair while i've been under the impression that freezing fish was a humane way to help them to fish heaven. Boy was i wrong. I will be more thoughtful and try the other methods recommended here from now on.
Having just recently bought a new tank and gotten back into goldfish this is a very useful thread to read. The only thing that i would like to add from my previous goldfish experience is that even though goldfish dont require a heater, they seem to do very well in heated tanks. I hadnt been aware of this until i read an article in one of the aquarium magazines and decided to try it. It worked so well and the fish are nice and active as well as happy.
Im not saying everyone should do it but that i followed the article and that it has worked for me.
