Roy...not really. The black dorsal for Texas is much more common in both males and females than flowerhorn.
Odd that you would say that. In pure carpintis only females & very young males have a black mark in the dorsal. Also noticed that trait in my hybrid carpintis, no male over the age of a month or two retained this marking.
I've mostly worked with pure bred carpintis, even my sb hybrids were a very high percentage pure carpintis, I would definitely consider them green texas, not red. I've never worked with rt personally. I'm guessing the midas/red devil genes (or parrot genes) change the rules about the dark dorsal marking. So odd, in my greens I always could rely on this sexing method as a sure indicator, although I always vented them as well.Red Texas still very much carry this trait of the marking on the dorsal. And I've notice that many of them will carry the marking on the dorsal upwards into 5 inches...especially for one that have yet fade or has only pre-faded.

Now that's what I like, and trying to produce!
since you are in socal, I suggest you go check out a huge RT-kamfa that is really nice at Tong's near whittier blvd. It is HUGE and NicE. In my years of FHs I say it's a must see because of the size and goodness of that fish.
