Walter is a great name! I applaud. I used to own a male Calumma oshaughnessyi named "Walter". I paired Walter with a female Calumma oshuagnessyi named "Estelle". This is an old photo of Walter.

Your male Furcifer pardalis looks to have some discoloration possibly from a shed. That black stripe does not look overly problematic medically speaking.
