BLUE TONGUE SKINKS

Hello! Yesterday i purchased my first blue tongue skink and i love him! Unfortunately i do not know what type of bts he is, i have a feeling he may be some type of indonesian but i’m not 100% sure so any help would be massively appreciated.
These pictures are from when i first met the little guy, i have not yet handled him since i’ve brought him home because i want to give him a chance to settle in, he hisses at me when i go in the tank to change the water / give him food, bless him he must be so scared. He’s a baby which i’m really happy about because i can raise him as my own
Also, i have not yet named him, i just have no idea! Any suggestions would be great

Looks Halmahera. Indonesian is correct. Needs very high humidity. Can you post a few more looking down at him?

Here he is, managed to handle him for the first time since getting him home and snapped these pics❤️

In this picture he appears to be Merauke. First pics were a bit darker, made me think Halmahera. Indonesian nonetheless. Requires high humidity. Adorable little guy, good luck with him!

I think merake or maybe indo?
