If your snake has those 2 dots, it's a
Thamnophis proximus ssp. (subspecies). If the snake don't have any dots or only one dot, it's quite possible thats an
Thamnophis sauritus ssp.
For a clear identification we need some good pics of your snake (top and side pics). If i interpret it right, no one of the pictures showing your snake, except of the pictures with the cage?
We have a thread with some enclosures:

As Rox already said, you need some hiding places and a larger tank as the snake grow.
