I suppose it really depends on the individual snake. The male I kept for 19 years became calm enough after some months to do the necessary maintenance in the enclosure without getting bitten (too often), you could even tap him if he was in the way and would move away. Getting him out of the enclosure sometimes provoked some defensive display and the occasional bite, but as most snakes if you had him out he would calm down.

However, I was never really sure about his reactions, he would try to bite in situations he usually would just sit and watch me, so he was more unpredictable as a lot of other snakes I keep.
