Is this a zebra eel or a banded snake eel?

Real hard to tell from your picture, need a good pic of the head but from what I might be able to tell it is not a zebra, the head of the zebra is very rounded not pointed at all which is what makes them so safe in your tank

What do you think it is? Is it a reef safe eel or will it get too big and start eating gobies and shrimps?
 
As suspected not a zebra not sure about your small fish depending on his temperament but for sure your shrimp and crabs or other inverts.
