Dicrossus Maculatus Sexing

[PamC]

Was wondering if anyone understood how to sex Dicrossus Maculatus.
I imagine they are not juveniles as one is about three inches and the other is two inches long.

I'm no expert on these but just did a google search it says the males are generally larger and more colourful

Thanks for the effort Monty, there is not a lot written up on them. I did find a site that I had to use the Google language translator that gave detailed differences. If anyone is interested
