okay, so i've posted briefly about this here, but get a biiiiig tank and some 25 cent feeder goldfish. people can't tell the difference between them and koi and honestly, they're pretty. we got to be close enough friends with the sushi chef at the our local place that we had him over for game nights and he wanted to buy our 25 cent feeders when they got like 2 feet long. we couldn't take a hundred bucks for a 25 cent fish named Lunch
