Sexing Borellii

I purchased these 2 Borellii as a male and female pair however I believe they are both female. What are your thoughts?

I think it’s very hard to tell without knowing a bit more. Especially how big are they?
A guess would be that the fish in the second picture is a female. First one, is impossible to tell from this picture.

I’d say they’re around 2-3cm I’ve attached a couple more pictures of the one which gender is unknown, thank you

At 3 cm it means that they probably are still juveniles.
