Recently my leopard gecko Pardus has begun getting blue spots on his body. They are behind his eyes, and where the stripes on his back are disappearing. There is no blue on his belly. He eats perfectly fine, drinks water, and sheds all normally. He's around 2/3 months old. His size is 14 grams, 6.5 inches. He was from Petco, so I have no idea what he'll become as far as morphs go. I want to know if this is normal and not a health concern. Help, anyone?
