Seems that I really lost the adult pictures. The juveniles and hatchlings I've seen looked pretty much corn to me, what is still a little irritating me is the fact, that "frosted-hybrid-pattern" goes along with the yellow head most of the time and that a corn with the frosted pattern resembles the head...
I don't want to say they are hybrids, I've read the whole discussion in the past - it's simply a fact to think of. Perhaps that kind of pattern is some how linked to xantophores in some way... :shrugs:
