I agree that is a wandering garter (vagrans) and man, he sure is long. Anyone else notice that? Yeah drui is right, he should take to pinks no problem. Just cut them up into a few pieces while they are still frozen. I fed pinks to my albino radix when she was even smaller than that guy. Chopped night crawlers, pinky parts, those would be great choices for him. If fed mostly pinkies and kept at 80-85 degrees he'll grow very fast.
