@Thekla I did buy him as a sexed male. The seller explained that she takes each molt under a microscope. She said she did breeding Ts as a side hobby from teaching. He's about an inch and a half or more? Def under 3"
@CrazyExoticLady Sex may or may not be super obvious at that size, but whatever sex it turns out to be, you can't go wrong with a pulchra. (Mature male pulchras are desirable as studs, because the slings are expensive.)
