Your best starter Tarantula. For a first pet, I would recommend this great 8 legged friend. With a body legth averaging 3 inches and a legspan of about 5 inches, this fuzzy friend is a simple spider to take care of. They eat smaller prey such as mice, frogs, and lizards. Females live up to 20 years while males pass away a few months after mating, so make sure yours is female!
