Maybe it's an Anery type E, LOL...
Couldn't resist, I saw someone selling one on the classifieds recently...
"anery type e is bloodred and where the black markings should be there white"
"anery type e when bred to a motley can produce coral zig zag corns, coral motleys, regular anery and also motley when bred to a motley"
Am I the only one who finds those descriptions incredibly confusing? The guy simply would not tell me its genotype. When I asked for a picture, he replied with "too late, sold."
Yes, I've heard that sunglows can have some white on them and they can grow out of it. That doesn't mean this one is a sunglow. IMO a "good" sunglow also has a bright orange background color, like rev okeetees and flourescents do. But I think that last part is just a matter of my tastes.
An Amelanistic bloodred will have a patternless belly. A non-bloodred will have checkering of some sort... white and "clear" or white and yellow, etc.
Also, I don't know if the hatchlings express this when the're very young, but IMO a "high-quality" bloodred would show signs of fading on the sides of the saddles, where it blends to the background color instead of being sharply defined. And... the side blotches coming up from the belly should be either very subdued or not present at all.
These are both traits that can be pretty variable, which require someone with lots of experience and a good eye for predicting their color changes, and which could easily be sold to someone who wouldn't know the difference until the animal is grown. (which is too late) If I were to buy anything that is not a simple "on/off" trait I would be sure to get it from the most reliable sources possible.
I'd also keep in mind that many pet shops and even some herp shops will either unknowingly or intentionally mislabel something--or just make up a name you've never heard of--in order to make it more "appealing."
