Help wigh (allegedly) A. cacatuoides identification

[FedericoBuggi]

Hallo everybody,
I recently bought a few A. cacatuoides, but looking at each one of them more carefully at home (too late, as usual) I am not really sure that a couple of them actually are cacatuoides.
I've been raising just a few of them in the last three-four year so I am not an expert at all but the shape of the snout/mouth of both genders and the dorsal fin of the male really do not look like cacatuoides to me. Neither I haven't been able to spot any similar species, so I haven't a clue.
Can anybody please help me to identify this fish?
Do you think that a display like the one in the third picture guarantees that both male and female belong to the same species or may it just be a common interaction between individuals?
I actually wouldn't mind having a dwarf cichlid that is not a cacatuoides, but firstly I am curious, in particular about wether my water fits, and secondarily I wonder wether they are a couple or not, since there no other cacatuoides in that tank .
Thanks in advance,
Federico

Hi all,
I am famously poor at this, but they look like A. cacatuoides females, you can see the black edged pelvic fins that indicate they are female, and the 3 stripes of the lower flank that suggest they are A. cacatuoides.

I have to agree with Darrel; they are A. cacatuoides (domestic form of some kind) and probably all are females. How large are the fish?

Thanks a lot for the quick reply!
One of the fish (the one I understand to be a female) is slightly more than an inch (3 cm) while the one that in my mind was a male is 1,5 inches (4 cm).
Actually the two-females option would fit with their mutual bright-yellow display when they meet (I never happened to see my other males that color).
Really thanks a lot!
Federico

@Mike and Darrel

You both were 100% right! I moved her to another tank where I had placed a male that shared the tank with her at the shop and they immediately resumed courtship behaviour.
Thank you both a lot for the lesson!
