I didn't think I had fish, but I do. I have a pond, around a half-acre in size. My wife stocked it with ornamentals like koi and comets. She likes them, I'd rather have fish that can be eaten. Anyway, the pond had a leak, so I ignored it for about six months. It had dried up to nothing but a couple of shallow puddles, and I was sure the herons had eaten all the fish. I finally got around to sealing the leak and refilled the pond a few months back. So yesterday, my wife walks in the door and says, "Guess what we still have? Fish!" So, I walked up there today and saw a dozen or so myself. How they could have survived in that tiny bit of water with no food while subject to predation by birds, snakes, and raccoons is pretty incredible.
