I couldn't have said it better myself, Jayzun. Anyone who wants to collect T's owes it to themselves to learn to sex them, themselves.at 3 to 4 inches it becomes more and more easy to see epiandrous fussilae, if there are any, so it doesn't matter the condition of the molt. At that size, I've known the sexes of most of my t's, both here and at work. These guys are right. The bigger it is when it is offered as unsexed, the more wary you should be.
Knowing to look for epiandrous fussilae is going to forever change how young t's are priced.
