My snake sometimes rests dangling from a vine or with his head and tail sticking out of his hide but the rest of his body hidden. He's afraid of water and likes sunbathing (only in the sun whilst handling, and is given the choice to move out of it). He aslo spends the night trying to exit through the air vents on the side of the tank, just turns it around a lot.
He also eats in the most peculiar positions which must make it harder, but he eats well so I don't worry, I guess it is just his personality.
