you don't need to turn the setup on its side until your crested gets bigger, then it will appreciate the vertical height. it is a pretty big enclosure for a small gecko right now, so don't worry about turning it.

do you plan on feeding insects or crickets? if so you might consider using paper towels or a much finer substrate as those big chunks might get grabbed up and cut the gecko's mouth or eaten accidentally which could cause impaction.

also, make sure that the water is your dishes is very shallow--about half the height of the gecko so that you don't risk it drowning.
