Cute snakey!!!
A couple of things...
-How big is the viv? It looks very large relative to the size of the snake.
-If you can cover the sides and back of the viv it would help to increase the snake's sense of security.
-The snake probably doesn't know where the hides are and doesn't know where he/she is!! Just give her/him some time to adjust before doing any holding of the snake!
