According to the pet shop guy my BP is a male. He determined this by looking at "his" tail. He is definitely a juvenile so I know it can't be accurate. However, his anal spurs are pretty long, and his head seems smaller in comparison to his body than the adult female BP's I've seen.

At what age will it become more apparent what his gender is? I know popping or probing would be ideal, but I don't know anyone who knows how.
