Just watch, you have 1 now, give it a month or so and you will be up to 3 or 4! Very addicting! I used to keep fish and thought that was addicting, not even close to keeping snakes! Fish were such a PITA to deal with, constant water changes. We had 130 gallon and 90 gallon tank. Would change half the water in each tank every sunday. I got sick of it and sold them!
