Got him yesterday and is living in a 75g community tank with an HRP and some tetras. He’s peaceful hasn’t showed any aggression. Really good looking fish. Not sure on sex.

Sorry I can't offer you any advise on gender but glad he or she is settling in. How are you going with your nutrient levels NH3, NO2, NO3 now you have cycled you tank. I'm interested in knowing if everything is staying stable for you and if your vigilance has payed off.
so far everything is intact on the cycle. Sundays are my water change day 50%. The only additional stock that will be added in maybe a few weeks is 2-3 dwarf synodontis. Not trying to have a tank where the bio load gets crazy.
With A coerleopunctatus, gender differences don't appear until about 4".
At that small size, they are indistinguishable (at least to me)
In mature males, like the one above have unpaired fins that extend to the ends of the caudal, and their body is slightly more elongate than females.
Above he is about 7"
On Females, like the one below, the unpaired fins reach about half into the caudal fin, and they are slightly more boxy in shape.
The also sport darker bands. She is about 4"
I find it is easier to tell gender when a pair are together, and one can see the contrast.
But coloration is not static, feeding on hair algae may exhibit light colors, whereas when feeding on a prey item, and be quite different.

Thanks for the info. Those are beautiful Duanes. Do you notice them to be peaceful or would you say semi aggressive?
I put about a dozen 2" wild caught Andinoacara in a 180 gal, by about year the alfa mail killed all other males, and a few non-cooperative females.
He allowed 3 females to live in that size tank.
He never bothered the non-cichlids when they were healthy.
Roeboides tetras, a pleco, and two species of gobies were all ignored.
At about 3 years, the tetras started aging out (they may have already been 2 yrs old when I got them), and started appearing frail.
At that point when they started floundering, the Andinoacara killed and ate them.
