We should have some 2017 hatchling Banded Charcoal corns this-coming summer. This 8-year-old female shows a little yellow in her neck region, but given that most Anery-types that have the genes to allow retention of carotenoid yellow have much much more yellow by this age. I doubt she will have much more than we now see, but the good news is that she should pass this genetic propensity to her offspring?
