Can someone sex my firemouth Cichlid?

I’ve had him (I think) for a while and I’m wondering if he is a he? I have two other females in his tank (one has layer eggs before and the other looks too plump to be a male) and he hasn’t shown interest in them only than chasing them away. In these pics I was trying to get a picture of his vent and you can see it a little. I can pick him up and vent him if need be and post those pictures as well if you need them.

The water is a bit cloudy cause I just did a water change

Looks like a male to me. Pic is a bit dark but he seems to have quite a long extension to his dorsal.

Here’s a lighter pic

I'd be pretty confident that's a male.
