Give him a week or two alone. Only change his water, check temps and humid. other than that leave him alone. My guy was very fiesty at first too. He still has his moods. He usually gets tense on Weds (the day before I feed him) and Fridays (the day after I feed him) late Saturday through Tuesday he's usually fine. Just takes time an patience every snake is different so you gotta take note of the way he reacts to things. Hope this helps.
