Most snakes are shy, some like to boot around and be visable but I think if you just got him it's too early to tell. He will need time to settle down. I had mine for 3 months before I started seeing him peek his head out now and then, and he seems to be getting more confident as time goes on. My other I've had for a month, I haven't seen him out yet.
And welcome to the forms! nice looking normal you have there.
