What do you look for when determining a fire from a normal.
color , eyes , belly , pattern etc.
I have this male that first of all may be a granite but he also has other features. He is much lighter with more yellows than a normal and continues to get lighter, plus he has green eyes.

heres a couple pics of him with a normal. These were the best I could get, he looks lighter in person. I will need to take some shots of him in sunlight then you can see his true colors better. Gotta wait till next summer though.
