What is the longest living pet you have owned?

The oldest animal we have in people years is our 19 year old jumper horse, but if we can talk about the age of the pet compared to the lifespan for that animal, I had a beta fish who lived for four years. Those four years included being abandoned in a dorm room over the summer before he belonged to me, three apartment moves and one car crash (We were picking him up from the lady who looked after him while we were out of town...long story. He wound up on the floor of the car and got thrown back into an inch of water. He lived for another two years.)
