I'm new here. We don't have any frogs yet but I'm wanting to get a couple of fire bellies for my kids...Don't worry, when I say "for my kids" I just mean that they will name them and look at them and I'll do everything else.

I'm really excited about setting up the tank. We have a 10gal and a 20gal long in the shed. I'm not sure if the 20g holds water as we used it for a tarantula years ago. Anyway, I've been looking at different set ups and I really live the ones that are half water and half land but I'm confused on how you clean them. We've got a 75g fish tank so I'm no stranger to cleaning tanks but it just seems complicated to change such a small amount of water. Maybe I'm overthinking it. How do you get the water out? When I change the water in our big fish tank I leave several inches of old water in...which is more than the frog tank would even have. Could someone walk me through exactly how they clean their habitat?
Also is there somewhere with pictures of other member's set ups? I need some ideas.
