What is a good nickname for a boy who is quiet?

He has jet-black hair and eyes that are a lighter navy blue. He's really quiet, but sweet. What's a good nickname for boy like that? His actual name is Zane.|||Just zane lol or Maby ziggy random yes but different|||Zane doesnt really need a nickname. I think its short enough already. It is a really beautiful name and i think it would suit a quiet person really well.|||I agree with Steven; Ziggy sounds awesome.
