Looks like the kkp had a heavier influence on the angle of the snouts of the young. I would just call those a gb flowerhorn/kkp mix. As for sex, you might want to vent them.
Bro, that fish has same tail as my biggest fish. Orange one. Thats crazy u bred the same type lol . Here is 2 of the females im bringing up. 1 looks like a gb fader and other looks like... cencu looking blue pearls everywhere
F1 Gb kamfa x kkp males are not interesting for further breeding. A high content of kkp genes causes infertility. Females are more promising. Hope the color changes. In such crosses, red specimens are often obtained.
From what I understand, and could be way off target, but kkpx srd or any known Fah strain produces F1 Kamfa. I did SRD x KKP and got some very unique ones from the mix. My best were deep red kamfa style, and then most of what you have here.
