Stop the press.... hold up
100 dollar tank? why spend more money on a less adequate enclosure when a sterilite tub with a heat pad and a dimmer switch will work a whole lot better, AND it'll cost alot less.
Any new snake you bring in, ever, always quarantine... some things an animal can carry and show no symptoms of for up to 6 months, but will whipe out your entire collection.
As far as housing snakes together... only time you should do this is during breeding. Snakes are solitary, they don't like to be around other animals at all.
Last but least, easy on the cap locks man... it hurts the eyes.
