This is quite a good idea. What would you do for the heating ?
I'm thinking about using a large one at the middle, it may be easier to control temperature as there is only one source of heating.
Maybe I'll go wth this idea.
Does a tall tank has an effect on the snake's behavior, stress, or wellbeing ? Or is it only a matter of keeping temps at a good level ? Because my 55 gal is 50cm (1.6 foot) high, and I have no problem keeping temps at a good level.
