I have some pics of two snakes who I think are male and female. *Note- I toyed with these on my comp to try and get the scales to show, so they do look a little... funky...*
Name: Broler
Length: 12 inches
Tail length: 3 inches.
Supposed sex: Male
Name: Cinnamint
Length: 14 inches.
Tail length: 2-2 1/2 inches.
Supposed sex: Female.
The ones that I think are male appear to have thicker tail bases, and this continues a bit past the vent.
