Why so small?

This is my red ackie, she’s 16 months old, why is she so small? I have a yellow one too he was much bigger at that age.

Females are smaller as far as I can tell.

My female was about the same length at that age.

Every animal is different. I have some ball pythons that are huge and others that don’t grow fast. Looks very healthy

Could just be the difference in the individual, she doesn't seem insanely small from the pic or anything. Is your yellow a male or also a female?
