At only 150 grams, though? I have raised juveniles to this size myself, but am not sure a "male-tail" won't come out of nowhere one day. Just wondering at what size gender becomes pretty evident...absolutely a female
Do you know how small this species is as adults?Gender unknown. Far, far too small to tell. Every tortoise looks female to start
It is physical size that is important when sexing. The actual size varies from species to species, but 5 inches straight line length is a good start. Some species have to be bigger than that even for certainty.
Some will 'flash' quite small. A male's penis is once seen never forgotten. If you see it then you have a male.
