Question
what is the difference between a female and a male african fat tailed gecko?

Answer
Dear Sadie,
thank you for your question.
Look underneath the tail: males have a row of small pores (like thick scales), femamles don't or at least the pores are not as obvious with them. Males also have a thicker base of the tail.
Here's a website that describes it very well:

I hope I was of some help to you
