No way to tell if its Malaysian or Sumatran

But more than likely Sumatran

Borneos are a completely different species all together. So no, thats not a Borneo

You have the correct species its just that truly red animals are usually bred for and can fetch some pretty nice prices.

This animal will probably stay about this color, though will darken with age.

This is why its important to buy direct from breeders who have put the time and work into breeding the best specimens they can get their hands on. Breeding for whatever color they want. Mostly reds, though high yellow animals seem to be liked by some.
