Is my p.auratus too small to ventrally sex?

Mr T is about 6 cms. Is he too small to tell yet? I’m interested in an educated guess while I await a molt. (is it molt or moult?)

looks male to me, but if so, his fusillae has not developed yet.

I was edging towards male based on the ‘notch’ I see on the line. Is that what I’m looking for?

Yup. That's called the epiandrous fusillae. I don't see it well developed, so I am only guessing.

Thank you.
I thought he may be a little too small to tell yet, but he was in a prime photo position.

Okay so if I’m reading it right, Rita Hayworth here (a.chalcodes aprix 10cm) is a female?

Suspected female is what I meant to say
