You MUST HAVE A HUMIDITY GAUGE!!!!! Frogs are dependent on soil moisture, air moisture, and a source of water to bathe in that is shallow. They are tropical so their enclosure must reflect the climate in which they're from. Amphibians must have a humid environment with the exception of a few like Toads who like dryer climates. Lack of humidity can be detrimental to the frogs health. You must have no lower than 70% humidity. The ideal humidity level is 80% and is the best level to maintain. 82° is good for day Time temps, but night Time temp should be no lower than 75° and hover around 78°.

If you do not have a hygrometer in the enclosure you have no idea what air moisture levels are and its not really something you can guess because even if you see condensation on the tank walls that doesn't necessarily mean you have the correct humidity even though many have claimed it to be. Those people of course cannot be certain. You also didn't answer any of the questions I asked above about age of the frog, how large he is or the questions in the link I posted.

Do you de-chlorinate your frogs water for his dish, misting, and water used to expand his substrate or saturate it?
