Look RTG to me, possibly of lower quality but still nice
Regarding his shine, could be genetics as Dloks infers, but plz tell us more about how you're grooming the fish (to bring out his best)? (e.g. size of tank, how often water changes, diet, etc.). If all those things are good then yeah maybe not greatest genetics, but he's still a cool looking fish.
Now it is alone in 150gallon tank 5’x2’x2’. I’m ready to upgrade my tank once he reach 20+ inch. 30% water change once in a week and filters are always on.
Feeds him once in every day. market fish, dry shrimps and OF_ARG1 pellets, these are his main diet(but he has less interest in pellets), occasionally give feeder fishes, market prawns, live lizard & crickets.
I got him in 12 August & he was about 4.5” in size. Now he is 15” ie, having growth rate about 1.5-2” per month.
His tank is in my out_house and he gets sunlight regularly, tank background is black and is bare bottom, there is no tanning lights, I use only normal led_lights 1-2hrs a day(because my old silver_aro got eye_drop due to continuous lighting). I don’t know wether i need to get tanning lights to get those gold shining.
Well looks like you're doing everything about right as you can for now (though I would forgo the occasional feeder fish in my personal opinion, just taking too many chances).
Tanning lights aren't really useful/needed with Crossbacks -- and at best it would only temporarily color him up (and if you used them too much you risk over-tanning/sun burn which results in grey/black color on top of the fish).
But what surprises me is that you say he's getting regular sunlight -- that right there normally would help a lot and should result in some great coloration. Given that your fish hasn't really colored up despite getting that good sunlight, probably means that you have to accept the likely fact that the fish's genetics aren't great, so I'd say don't worry about and just enjoy your fish as he is -- and who knows, someday he might surprise you by coloring up more.

Thankz a lot @dovii , But itz so sad to hear those, I spend $200 for this, was not aware about genetics quality, It was too late for me to find that I was fooled with fake certificate from unknown farm....
How do you know it 's a faker certificate? Do you know someone with a tag reader?
Also I don't know if prices there are way different than here in Thailand, but from my market research you to kind of spend closer to $500-$1,000 for a good Asian Arowana (and about double that for a really high quality fish). So for $200 imho you weren't really ripped off or anything, but again I don't know local prices where you live.
