I'd like to know who shot it down...
This theory has been around for quite sometime. When I first joined the "fat frog" hobby a few years ago, this was common knowledge on a forum that no longer exists.
While it is a good way to detect males early on, Youngsters like these with smaller heads can and do also turn out to be male.
A long with the head size they also believe young males have longer legs in comparison, maybe you guys can put this to the test.
Though in case you all didn't know 90% of pyxies can be accurately sexed at 4 inches.
