Cockatoo Apistogramma question

[Mtl Parrothead]

I picked up 3 cockatoo apistos a couple days ago, I was told there is 1 male and 2 females they are still quite young. I personally don’t always trust the opinions of the employees at my lfs

1)
Pretty sure male

2)
Think female

3)
This one is the smallest but think might be a sneaker male

Opinions

I’m not looking to breed but would not be upset if it happens

Congratulations on the new additions. (Can't help with the sexing) These are neat fish.

Thanks, found out actually 2 were males, returned one now I have the 2 smaller ones.
