Do I have a ghost/hypo?

[MarkS]

Het Hypos are definitely lighter/cleaner than normals a lot of the time, I have noticed. I wouldn't say I could spot one in a pile of snakes definitively, but I think there is a subtle difference.

Not necessarily. I've got a het hypo female who was the darkest snake in a clutch of possible hets. Also if you look over some of Ralph Davis' oldest breeding records, he has a line of dark looking animals that he was calling Anerythristic that turned out to throw some really nice hypos.
