Very nice looking noodle!
Looks like a pastave. If not pastel mojave, possibly pastel mystic. I feel like mystic potions were fairly popular around that time and the non-allelic offspring can be hard to tell apart.
If you do look to rehome later, for situations where you aren't 100% sure on the genetics, I always like to give them the "appears as X" just in case and let them know that you don't know the background on the animal and are hazarding a guess at genetics. If they're planning to stay with you, that won't matter of course =)
One way to be sure would be to try breeding to something carrying one of the genes in the complex. My gut would say mojave seems most likely. So you can always try breeding to another mojave, special or mystic to get that figured out depending on what the offspring end up looking like.
