German Blue Ram sex?

[Eschie]

So I have a few GBRs in my 20 gallon and I'm hoping a couple pair up but I need help sexing them.

This is the newest one. He's kinda pale but I'm pretty sure it's a male. Any opinions?










The next one is the oldest. Her belly gets bright pink so I'm pretty sure it's a female.





The last one is the one I'm mostly not sure about. I'm leaning towards male but totally not sure. Sadly he's also hard to get a picture of haha

Got a perfectly posed picture of the third one!!

Male. No blue in the black dot as well as his front belly fins are longer and go to a point. Beautiful though
