Advertisement Hey guys. When you buy a tarantula off the web... how are you able to be sure they're the sex you were charged for? Is there a way for me to sex it without touching it? Also would it be worth buying a 4 inch female chaco golden knee as my first? I would prefer a larger specimen.... but I wouldn't want it to be 10 years old... if it only lives 15? Also what are the fastest growing tarantulas overall? Would you say keeping temps at the higher end affect the growth rate? Thank you for your patience.
