Yep it's a Sooty Grunter, believed to be an Albino. It seems that the lack of pigment in a Sooty causes the bright Orange colour instead of white like most other Albinoes. A mate of mine has bred many sooties before an would have to admit that he has witnessed many that were orange.
so it's kinda rarish to see one, but they look cool.
bout time someone got the id, even though amehel0 hounded me for the answer
