Dose the frog have a coat of slime on it that eggshell white kinda cloudy, I've seen this before in a frog if its got a coat like that on it its dehydrated, not humid enough either way. The humidity needs to be between 75%-85% in the tank also a common mistakes is the humidity gage should be closer to the soil for accurate readings. There terestreal frogs so air humidity don't mean squat. Hope your little thing is OK
