Sexing Apisto SP Masken.

[Microman]

Is it possible to sex Apisto SP Masken at approx 3/4" total length,i have 2 broods at this size and i am finding it difficult to find the differrent sexes.
I am also having the same problem with Apisto Vijieta CF 2 which are also approx 3/4" total length.
They were bred at 80f so there should be a reasonable mix of sexes,maybe slightly in favour of males.
Any help would be appreciated.
Thanks,
Mark.

The size is a bit small for accurate sexing. My Masken males at this size start to show red markings on the face and pale bands in the tail.
