The aggressive behavior you are describing may result from stress. Snakes are incapable of emotions or attachment to another being. They do not have social skills or love or hate. This is because they have no frontal lobe. Ball pythons like living alone, all of them, all of the time. They only interact with another ball python in the wild to breed and incubate/hatch young. This is fact, for sure, absolutely, no questions asked. You should sell the female now and keep the male mojo alone in your nice display tank.
