Goldfish

Last weekend while I was in Seattle visiting family and friends, I met at my parents house a 15 year old GOLDFISH!
can? you believe it? I almost couldn't. My parents where pet-siting this lovely creature who was swimming around super fast around the fish bowl. I think if someone tells me about a 15 year old fish, I would picture it in my head as a slow and ugly fish, but this one, I must say, just change my paradigm about fishes. Do you know about any goldfish that old?
