Ok, the temp shouldnt be in the 90's. thats way too high. It should be 78-80degrees. And you need a humidity gauge to measure the humidity because the humidity should be between 65-75%(thats what i have read in a lot of websites). And with your temp you should definitely not use lighting because thats an unspeakable amount of heat if you put a light, but you actually do need a light when it starts to get colder because they need that heat then. But i still have no idea why your frog is sick though...as i have said, im not an expert, im 12 lol. But i hope your frog feels better!! And i hope one of the real experts help you!
