Rule of thumb is wait a week to allow the animal to settle before handling.
He's not aggressive. It just sounds like a distressed, frightened, insecure snake.
I suggest you cover 3 sides(sides and back) of the tank with a background or solid black paper. This will help to make your snake feel more secure. Big open spaces scare babies. And cluttering the enclosure with decorations, fake plants, or balled up paper will help too.
