Probbing amazon tree boa...

[Francois]

Hi!!!
I'm need information about sexing corallus hortulanus. When you're probing a male, how long the prob the should "enter", and for a female?
What's the best size for probbing an amazon tree? I know for c. caninus and for morelia viridis it's very dangerous to prob a young, but is ti the same things or an amazon tree boa?
I will wrote my question in french too, because my english is.....ouff!!
De combien d'écailles doit s'enfoncer la sonde lorsqu'on "probe" un amzon tree boa??

Thanks you very much!
Francois
