Just picked him up yesterday, his name is Freddie (I figured the "ie" made it a unisex name should he turn out to be a female). He is really bold and curious, already eating and everything.
So your gecko is 5-6 inches long? That is about half grown, definitely should be sexable at this point. If it doesnt have the bulges and well defined pores its a female.
Ok, I didn't know they were sexable so early. I just got around to sexing my other two and they're 9 months and a year. I looked last night and saw nothing, so I must have a female. Maybe I'll rethink the name.
