Had a freak hail storm on Saturday in Chicago. There was about a1/2
inch of hail (1/4in size) on my deck. The size of the pond is
10'x4'x3'D. I lost 7 goldfish (about 7" in length). What happened? Did
the hail cool the water too quickly? This never happened before.

They probably did the same thing my stupid fish do in heavy rain, come
to the surface to see if food is beeing thrown in.
