I really love the blue on yellow. He had more potential to turn more orange. If you look at one of your picture. He started to have the front part of the body turning slightly orangy. I assume he would turn full bloom orange when you show him another male panther or maybe in a couple more shed. You did a grat job raising him. Too bad you don't have any female to paired up with him. If you would like to produce some really nice red body blue barred babies, Pams Chams have some 2-3 months old female babies available. They are sired by Meka, an awesome red on blue ambilobe. I bought a baby male from her. He is showing a lot of red at age of 3 months old.
