LOL very funny ;p
so how do u get the southern one if someone doesn't sell it to you?
i come from the country which these snakes originate, their natural habitat is in my country..
but even so, most of these snakes (both northern & southern) are wild caughts, even the babies are also WC, the best you can expect is CH (Captive Hatched)

Nevertheless, how do you differ the southern from the nothern in baby forms?
From the physical look I mean..
Many times i hear southern babies' scale look gold (I don't know if this information is true)
