It's a little tough to tell at that age. Usually you will be able to tell if there is a buldge at the base of the tail.
I remember when my cham was that small, man they grow fast!
Most of the time I think it's a girl but then after her first shed a hole bunch of bluish green appeared on her head and a little on body, so I got confused
I know how that goes. If you want try and post a close up of the base of the tail. Some females do show a bit of color on those areas, but you never know.
Yea I did , she sent me 2 prior to this one who didn't do as well and sadly didn't make it since they were only days old that I later found out , I'm thankful this girl is doing well and in my mind I saved her from a bad person
