Aggresive Baby

I have bought a new ball python my first accualy. hes fine to handle but when in his cage he strikes at the glass and not eating yet any suggestions? :)

As always:

How long have you had him?
What are you feeding him?
What is he houses in?
Temps? How are you regulating them?
Hides?

Go into as much detail as possible.

AK covered most of what you should add, another thing would be age, though it doesn't always matter as each snake has there own personality a younger snake is more prone to strike then an older one.
