Sexing A. lyonsi?

[Modest_Man]

I've read that females are supposed to get black in the dorsal fin, similar to other SA/CA cichlids. I'm not seeing it in my guys. Any tips or tricks? My two largest have more pointed dorsal and anal fins, but that's about it. If I had to guess I'd say two and two, but no signs of breeding yet.

6"+

5"

4.5"

4" (and pretty beat up)

Also figured I'd toss in one of the boss of the 5.

I haven't had good luck sexing lyonsi either. I have a 7" one that I still don't know the sex of.

I had one that I assumed was female but grew to nearly 11" so it must have been a male since females are not supposed to exceed 8". It looked like your 6"er but did not have the pink chest.
