Just wondering how often? How deep the water should be what temp

?? I gave mine his first because been to nervous trying to figure out those top 3 questions i got a little rubermade container filled it with luke warm water just to cover the bottom completely he swam around for a little licked water from the sides dipped his head a couple times he is shedding a lot so that just tells me he is growing and he is pooping on a reg bases so I am hopeing that's a indication that he is eating good. Also do dragons normal pick a spot to poop in and use that all the time it seems he goes to the same spot and goes there not sure if that's just coincidence or do they know? Sorry all the questions but I want to make sure I am doing the right things here

Thank You all
