I have taken two baby of t.johnstoni, they are 2 months old and the sex is not looked at. I think is two male. the females of this species have of the corneous plates in correspondence of the horns of the males? excused for my English.
I had some baby johnstoni years ago and they were large hatchlings. I think by 2 months it was clear which ones were males by how much the horns had grown by then. I would say if there is no horn growth by now then they are female, but I only had them once, years ago....
Coooool babies. I wish you the best of luck with them! I know they can be difficult but certainly not impossible. And when they are adults it will be well worth it
I can't quite tell which baby is which in all the pictures but it seems there is one that has no horn points started yet?
