Beginner Snake for a 406 tank

How quick do they move? One of her favorite things about the BPs was that they were slower moving.

Young Kings are really quick. You could look into sub-adult or adult Kings though. They are much easier to handle as they get bigger.
My Cal King, Django, is my favorite snake I've ever kept. Just a really cool and easy species. And you shouldn't have to worry about feeding strikes, Kings are notorious garbage disposals.
