Ivanacara adoketa vent photo

[shamedonor]

Hi. I'm currently looking for a female for my I. adoketa male and wonder how to make sure if a given fish is really a female. I found a fish but it is not really clear if it is a female (the owner is rehoming as they did not form a pair with another male). From what I got the only sure way is the vent shape. But since I have 2 males I cannot see any difference so I wander if someone could help me with that and provide me a couple of pictures of the female and male vents?
I saw at my fish that the male`s vent is like a barely visible almost round hole, rather closed and without any special thing around, On the other hand the owner says that he saw some small difference. The fish in question has a vent which is a little bit kind of open, more visible and not elongated. But from what I feel it is not clear enough and a couple of pictures would explain much better. Just want to make sure I'm not getting another 3rd male.

Thanks

The vents (anus) are the same on both sexes. It's the genital papilla that are different. On males it is small and pointed. On females it is larger and blunt (ovipositor). This is common to all Chilasomines. Sadly these are most pronounced when the fish are about to breed.

I have only such pictures of my males. The potential female owner didn't manage to take a picture yet so need to wait another try but visually she said it is a bit different

How?? I need your superpower!
Is it the same fish, I meant does the female have always more distinct zebra pattern or they are kinda from a little bit different color groups/locations?

Mature females always have darker faces than males. Mature males show more distinct sub- and supraorbital bands than females.

Hi. Here are some new photos of those two fish. The file name first part (1_x or 2_x) means a given fish. What do you think? From what I see the #2 is definitely a male, but the #1 might be a female. Both fish are mature.
Thank you!
