Parachromis friedrichsthalii id help

[Twonvito]

I have 3 parachromis friedrichsthalii which I'm having trouble identifying sex. One I believe to male kinda keeps everyone of them in check. The first one is the one I believe to be Alpha male. The last pic is the same one as the first one.

I'm not seeing any that stand out to me as female. I have a female and she has very black eyes, and her fins transition to near black on the ends kind of like a GT male ends in that orangey/red. She's quite a bit more iridescent with dark black highlights than her male.

The first one looks male, second looks female, and the third is too small to tell.

Bump

Ok, after I had my last 3 killed aling with other fish by an accident. I got 3 more but I can't ID them. 1 is 3 1/2", 1 is 3", 1 is 2 3/8. Anyone can tell the difference

Heres a pic of my 7" male. Your "alpha male" looks more male compared to the rest. Its hard to tell from the pictures.
