More sexing of Caca

[GliAzzurri]

Hi, this is my first post on this forum, and is brought on by dire necessity
I've got 3 apistogramma Cacatouides which I'm unable to distinguish male/females.

I've had these three for 4-5 months now, but I'm still unable to say for certain which is a female... If any of them.
I'll attach the pictures:

The first picture is a male, I'm quite certain. It's much bigger than the other two, and has all the male telltell signs as far as I'm concerned. It's also the dominant "force" in the tank.

The second picture I think might be a male.

The third picture I hope is a female, but I worry it might also be a male.

Can anyone give me some pointers?

My guess is that they are all males. Females don't typically show well developed caudal fin extensions.

Thanks for your reply. That's what i've suspected too. I'm still uncertain about the third one. What's strange is that there really is no fighting/quarrel over territory in the tank between these males. I guess it would change if there were females there too though

Pretty sure is all male. And commonly in a batch of captivity breed cacatoides will be male predominant.

this is a female for sure you can compare this fish with yours

Here is one more picture of a female that you could compare
