Your snake is most definitely a hypo. Hypomelanism is the reduction of black pigmentation. Anerythrism is the reduction of red pigmentation. A hypo anery is a ghost - of which Minguss showed you a picture.
A Salmon is a specific line of hypo. Unless you have documentation from this snake's breeder, there's no way to know if your snake is a Salmon. But it IS a hypo. All salmons are hypos, but not all hypos are salmons.
Very nice pickup by the way!!![]()
