6 months to 1 year, depends on whether the cloaca is prominent or not. Also males develop 'dirty hands' which are used for mating, though this isn't always a sure tell tale sign since I've seen females develop them too. Females are also much larger than males.
How strange. The one I think is female is a little larger than the other one and definitely has a prominent cloaca. Only she doesn't look like she is quite six months old. She is still smaller than an adult, maybe about 3" when fully stretched out.
