Looks like a possible f2 (second gen) kamfa/red dragon cross. It's a pretty common cross when it comes to FH's, most ppl breed these 2 FH's together to mix the pearling of the kamfa with the large kok of the red dragon. Still a nice looking FH tho, he has some nice finnage to him along with good pearling.
Definitely love the choice in substrate for him. FH's love to dig into the substrate so it's good to see that ya kept that in mind. Ya got any hides in the tank for him?
