Really sorry you had to loose your fish this way.

Well, the chlorine has done its damage. I have one gold fish and my
largest koi (20") on the bottom of the pond. They are both still alive,
but upside down and gasping for air. I assume at this point the process
is lost.

I thought about bringing them to the surface and a quick wack on the
head, but kinda like killing family...

Any suggestions, or will this all be over in a matter of hours anyway...
