No, I'm not sure, personally I think she may be a pastel ghost. She was sold to me as an anery motley het for pastel ghost(hypo like you said) but I guess I will have to wait until next year if she big enough and breed her to my male ghost. Time will tell. lol
It may very well be an anery het hypo mot. I had one that started out looking like a normal anery hatchling and lightened up even more than yours. He proved out as an anery het hypo when bred to a ghost female. Got 4 ghosts, 2 anerys, and 2 snows. :) Definitely do a test cross to prove it out, but the appearance as a hatchling and the black edging makes me think it'll end up being an anery het hypo. Either way, beautiful snake.
