i want a bad biter with a nasty temperment because i want learn hook handeling and how not to get bit in worst case senarios like a snake wanting to bite you whenever you open the cage, because eventually i would like to own venomous snakes and i figured water snakes because they can be mean and give bad bites, plus alot of them don't get to big. humidity disen't seem like a big deal, if i pay attention it shouldn't be a problem. but switching fish to mice would be the hard part becaus i don't know how to do that. how is switching from fish to mice done? thank you for the info.
