Looking good and the colors are beautiful. I believe the diet plays a big role earlier on as a juvenile and not the size of the flowerhorn that helps it develop the hump. Good luck with the great looking flowerhorn!
it depends on the fish, and there's no guarantee on how big the kok will become! Just give it time and grow it out! The bigger the fish, the bigger the head it will develop, but you have to keep this in mind too, not all flowerhorns will end up with a big head! ! The picture below is a 8-9" Thai silk
