Help Sexing Apistogramma?

[hexy]

Hi All,

I have a trio of apistogramma cacatuoides in a tank hoping to breed them but have recently come across the phrase sneaker male (pretend female) and wondered if I may have one in my tank as have had no luck breeding so far:

Below are pictures of the 3 fish:

Male

Sneaker?

Any help would be much appreciated!

Thanks
