How long can fish survive out of water?

This morning when I got up, I passed the fish bowl, and one of the fish had jumped out of the water and was laying there on the ground. It was relatively dry, looked like he had been there for quite a while. So I poked him, and his mouth moved! So, I picked him up by the tail, and threw him back in, and he swam around in circles. A few weeks ago, our black fish, Destiny died. So, we got another one, that seems to be missing an eye, who was aptly named, Destiny’s Child.
