Nice pick up! Mala's don't get particularly dark for wolves so him fully colored up will be this or something only slightly darker. For the most part they're pretty peaceful but highly predatory so anything big enough not to be eaten will generally be left alone as long as they leave him alone that is. As far as him eating give him a couple of days if still a no go you may want to try shrimp stuffed pellets. I personally never got any of my wolves to eat pellets so the seller may have been mistaken saying he is on pellets, then again I could be mistaken as I said it's only been my personal experience with wolves that makes me think they don't take pellets.
