Geico is a Leopard Gecko . He doesn't do much except periodically wander around his tank and eat crickets, along with the occasional waxworms for a treat. My wife wanted a gecko, so for her birthday she got one. We've had him for about 5 years, and he's been the lowest maintenance creature we've ever owned. He costs about 80 cents a week to feed, and we change his sand once or twice a year. He's never been ill, never been to the vet, and never peed on the living room carpet.
