there are a few people with possible axanthic coastals. to my knowledge the lines are not yet proven, possibly this season or next there will be a pair or trio breeding.
not my snakes but i would love to get hold of them.
No doubt a lot of the suspected axanthics will have been crossed with albinos to make 'suspected double hets'. It won't be long now (or may have already happened) that the F2 test generations should be hatching. If they are true axanthics there should be snows hatching this season or next, if they haven't already, but since only one in 16 of the F2s will be snows, the people with them will probably stay quiet until they have grown them up and are breeding entire clutches of them (for all I know that might have already happened).
If someone advertises snow carpets, expect a big APS debacle
