When I got this guy, the lady who sold him to me said he was male. It seems like he has the bulge under his tail, but no tarsal spurs that I can see. He is only a few months old, and I'm not sure at what age they develop these spurs.
Incorrect. The bulge can be used to sex many species. Exception mainly being the Mellers Chameleon. Veileds can be sexed by the hemipenal bulge its just way easier to look for the tarsal spurs.
