Your set up is almost perfect! The water dish should stay where it is because it will quickly evaperate if its on the heated side. Your pac does not use his dish because they they rarely ever do. The only time that my frogs have ever used a dish is when they are babies and happen to go through it while crossing to the other side of the tank. I still use a water dish, but sense they don't use it, I have a glass top on the tanks. I leave a 4mm space at the top for air and so that the humidity doesn't get over 100%. I keep them in coconut substrate that is 4" deep for the young ones. The substrate needs to be wet, but not like sloppy mud. When you mix in the water with your hands, there shouldn't be any dry substrate left. I t should be fairly moiste like a cake, and should also have your hands covered with clumps when your done. This will ensure that your frog never dries out and un able to open his eyes. you will need to check the dampness of the substrate at least once a week to make sure its not to dry. If your frog comes out often and the glass walls and top have condensation, then you have it right! Be sure you cover his food with calcium dust. hope i've beem helpful.
