I think it is C. proteus. It could also be C. lucius but you really can't tell until females start getting the dorsal fin spots. I purchased my C. proteus as "green pike" and that was the last I heard of green pikes (C. compressiceps is also labeled as the green pike sometimes). Here are a few pics of mine, so you can compare them and see.
Oh, as with most Saxatilis pikes, they are hard to ID. Even more so when they are small, so research and decide for yourself, but I'm thinkin proteus.
