Dimidiochromis Compressiceps sexing???

Hard to tell. Some male Hap will not color out at large size if it is not in dominant position. I bought my D Compressesep at 2 inch size showing male coloration, but lost color soon after settling in my tank. Now at 8 inch still isnāt coloring up much. There is a big male Moori dominating over the compressep, so I wonder if subordinate position could delay coloration or the initial coloration was induced by hormone.
I just vented my 8 inch D. compressep, and it looks like a male. Do you agree? I know the fish was hormones when I bought it as juvie as many whole sellers do to large haps to promote sale. But at 8 inch, it still has not colored up and I wonder if it will ever.It looks like a dimi comp, but that will become more apparent as it matures. Oh and congrats, it's a boy!
A general rule in venting a small hole small hole oo = male, some species the vent hole is slightly triangulated like your comp. Small hole bigger hole oO = female with the vent being donut shaped which becomes more pronounced after the fish starts spawning
The vent looks ever so slightly larger than the poop hole which would be female. Can you post a lateral in tank shot?
2 posts above #24 is a lateral shot of the fish. When I bought the fish as a juvie, it displayed male coloration due to hormone treatment. Iām wondering if hormone treatment could have sterilized the fish preventing it to mature sexually. I have also known hormone treatment has turned female temporarily into male. If it were a female, I would assume the big male Moori would attempt to mate with her. The Moori is the only other hap in the tank that has been picking on the compressep.
The pic in post #24 is heavily influenced by the blue lighting above its head. The dorsal is squared off, and no eggs spots or red anal fin. At 8ā it should be lit up if it was a male so Iām still thinking itās a femaleā¦.I could be wrong but I donāt think so in this case

Yes, the dorsal fin is squared off, but the top edge and the anal fin are orange without egg spots. Venting does not show obvious difference in size of the two holes. But at 8 inch, it ought to fully color out. So itās sex ID remains ambiguous to me until one day it attempts to mate or lay eggs.
