My female jumped out of her tank near her filter once. She was out of the water at least a half an hour, but she was ok amazingly. Her fins and tail had started to dry up and stuck to the floor when I picked her up and it took a while for them to grow back, but she bounced back.
I'm sorry your guy didn't make it. I keep a piece of cardboard over that tiny hole now so that it doesn't happen again.
