Speaking for myself I decided not to provide an ID on sex because you're asking for a ventral sexing, something that's often no more than a guide, a 50/50 choice.
Some people believe in sexing small Ts using Rick West's(?) method but its not something I trust myself to do.
To get a ventral sexing correct you need to identify the epiandrous glands and the thick patch of hairs above the epigastric furrow to determine male or lack of to determine female. However its not easy to spot this and therefore requires a good clear pic, some experience and an ID of the T concerned.
@ Proxicator - Thanks. I know its never a sure fire method. Eventually the exuvium will determine the gender. Just can't wait for the next molt, that's why.
The reason why I put it on the boards is for the other owners of the same specie to help out. Maybe they were able to observe their Ts when they were at this size and by now they have confirmation of the gender.
