I have exactly three thoughts about this video of a goldfish driving itself around in a custom-made RC tank. 1. Fish are much smarter than I think we give them credit for. 2. How neat would it be to have a bigger RC tank with a pet trout in it that just wandered around the house and came when you called it like a Lab? 3. I need it to be spring like tomorrow, because I'm spending way too much time watching goldfish driving RC tanks. Have a sane weekend.
