On several occasions, one or two of the koi in my rooftop pond have escaped capture and relocation to the indoor tank when the weather turned cold. During a January thaw a couple years ago, I took the opportunity of the first >40 degree weather in a couple months to clean up the deck a bit. After I took out the 2-3 inch thick slab of ice left in the bottom of a mostly emptied 45 gallon container a small fish gave a little spasm in the melting goop. "Lucky" is still alive and kicking. Checking out books on koi (aka carp, aka japanese goldfish), it seems as though surviving complete freezing/thawing is a recognized and common ability of these animals, even large specimens weighing several pounds.
