Should I have done this(Setup Help)???

[PDDM]

Im using a 5 gallon for a baby less then 20 days old,I was using it normaly but then today i decided to switch the tank to being on its side,so no its more taller then longer,was this a good idea???I figured it was cause now the crestie can have more climbing room,and also catch crix easy on the floor below,but the think is i have a screen top,which now is the screen door,im worried that i may not get the right humidity for this what should i do???I need opinions on if this was for better or worse,it also has 2 fake plants,two pices of park,and its babyfood dish. Its favorite plant is the highest up,its sticking to the tank,then it has a thin vine like plant in the middle sticking against the wall,it kinda has a lil stump on the floor ,along with the big piece of bark leading onto the thin vine.So was this a good or bad idea?
