Hmm.. I definitely see something "different" in these pics. The "ghost" is IMO different from a pastel ghost, and the "hypo," especially the hatchling, is definitely a more extreme expression of hypo... it almost looks like an Amel to me.
As to whether they are special, well, I don't see stripes as special, but it's definitely a different trait than all the rest.
To sum up, I hate the names, but it looks like it's possible that this is indeed something "new." (If I hadn't seen a similar "hypo" in the flesh I'd probably be a lot more skeptical, too.) I just wish we could get more (and more decipherable) information about it.
cka, I hadn't heard of the grey rats being mixed in to make ultrahypos, any idea where more information about that (esp pics) could be found?
