Yeah your guy just seems like a lil bit of a late bloomer. Most FH's tend to fade once they reach around 1-2in but some can wait till much much later to fade, even seen some that waited till they were fully grown before they started to fade.
As for color it's anybody's guess with a fader. Granted with how yours is going I would say it may turn out almost completely pink like my female red dragon. Also he has just started to fade from the looks of it so he may take a bit of time to fully color up again. This is my fader female btw, yours may end up somewhat like mine did.

Well i could definitely rule out stress because his kok got bigger lol. How long does the fading process take? He lost majority if not all his pearls and colors
