Halmahera and 'paulsoni' are the same species.
Halmahera Island Ground Boa is Candoia paulsoni tasmai and the more common captive is the Solomon Island Ground Boa which is Candoia paulsoni paulsoni.
What you have I am sure is not the nominate form (C.p.paulsoni). It may well be from Halmahera, however, I do not believe it is the typical gold phase that I have, and have seen elsewhere.
It is however different, and a lovely one at that. It has a lighter background colour, and a light eye colour. This makes me think it could be a gold phase, but the ziz zag markings and the head markings, speckles etc... are not present in the Gold phase Halmahera's I have seen.
The only way you can find out exactly what it is, is to do a scale count.
The counts that you need to do are:
Ventrals
Subcaudals
Supralabials
Infralabials
Circumorbitals
I also need a total length in CM, and the length of the tail in CM.
If you can get that, I could tell you the subspecies, and a likely island it has come from. However, in terms of its colour or genetics, this can only be proved by you through breeding.
