i had mine 4 like 2.5 months now. I got her from Petland in the Bronx. when i bought her i asked what sex it was, but i can still tell by the way the tail looks. the females have short tails, and after their vent, u can see how the width of the tail shrinks. the males have long tails, and the taper of their tails isnt as noticeable as the females.
