^^^The title says it all.^^^

Also any picture examples of males and females would be nice.
 
I agree. There are rough guidline for eyballing males and female, but it can be very innacurate. Venting is the way to go to know for sure.
 
When almost fully mature, the males (or at least mine) have a blueish head, more on the lower part though. The females do not have this at all. Males are also more aggressive.

I have noticed that females are usually smaller and not as bright yellow. they may have a more white belly and not as much black in their color. juveniles are difficult to sex.
 
Found out mine is female when her mouth grew 3-4x normal size......she was carrying fry.
2 survived.
no clue who the baby daddy is...............new hybrid.
 
All jokin' aside.......heres a not so good pic of my female note the anal fin is yellow n black... males are blue n black.............and she did carry fry 2 survived

Gotta vent them anything else is a guess.
I mean you can tell who the dominant male in a colony is by observing mature fish but the rest you dont really know if its female or a subdom male
 
I think if they have a crimson bluey shiny cheek and around the gills, they're male, but don't take my word for it.
