Hi I have a few questions...had my snake two weeks now, he eats well and seems to be fine but at the start he wasn't very aggressive at all but now when u put ur hand in his viv he shoots round it fast and rattles his tail...he's a nightmare to get out to clean etc.is it possible hea now become possesive of his viv but he wasn't at the start...also he never seems to drink....even after feed. ..do they drink much? I've done a lot of research but I think I am paranoid about him as he's my first snake. ...oh almost forgot,new viv coming today, 30×30×45.....is this a decent size, or too big too small...he's.about foot n a half nearly and wat size od viv is good for full grown? Sorry for rambling, thanks .
