I am sorry for your loss. Now snakes really aren't the kind of animals that should be snuggled and hugged and what have you. You also don't need to feed them in another tank, there is no reason to move them to feed. I would also take your remaining bp to a vet, as you don't know what killed your first one. Ball pythons are not social animals and should not be housed together. Not trying to be harsh I'm just trying to help.
