Safe bet to say female?

Tostada is 4" long. Even at this size, would it be safe to say it's most likely looking like a female?

Looks female to me.

Seems pretty young to tell but from my past experience, i'm leaning towards female because the guys seem to have a long and skinny tail while the girls are short and stubby at this age

I'm leaning female too.

I'm leaning female too.

Right? Can't imagine that tail suddenly sprouting. Especially at 4" already.
