There is however a flip side to this. Like everyone else said your snake should calm down especially if left alone and you let it get acclimated to its new surroundings. however sometimes you just get a snake that's mean or squirrely. if they don't settle down within a couple of weeks and are still really aggressive you can break them off their aggressive habit. you heard of fight or flight if you're holding your snake or it striking at you in its tank gently force it into a ball in your hands in clasp your hand on top of it. very gently keep packing it into a ball. do this for a couple of minutes and you will be surprised.this puts them in flight mode where they will coil up and stay in a ball. now you can handle your snake in it will be like handling a different snake .mellow and calm. my female pastel I've been working with her this way for a coupleii of months. I now finally trust her . good luck and don't be afraid to try this if your snake stays aggressive
