I read that you should start with a smaller tank for a snake and work your way up. This to me just seems weird that a animal no matter what size wouldn't want as much space as possible. Do I have to work my way up to a 75 gallon, starting out at like a 20 then a 40 and then a 75. This just seems like a waste of money, plus I am going to get some type of board/or paper and put it so it goes up the sides of the tank 1/2 way to 2/3 of the way up. (It is in a corner so the back and right side are *hidden* per say) I would also give it a lot of climbing space and fake plants and 2+ hides, Is this ok. (Dimensions L 48in by H 21in by W 18in).
