Thanks so much for responding!
My local pet store told me that I don't need a UVB light source for White's tree frogs, as well as several online sources and a book source. However I have read that amphibians and reptiles need UVB, I don't know if that applies to WTFs or if that's just a general statement. My current UVB light is expired and my local pet store turned me away from bothering to get another.
I would be happy to hear your opinion on this as I'm wondering if I still need a UVB.
While my frog is getting worse he also uses all energy to escape from anything that he doesn't like. This includes flicking mealworms away as they approach his front legs, avoiding crickets, and if placed in water or light quickly jumps away into sheltered areas.
Although he doesn't look healthy and hasn't eaten for like 9-10 days he isn't on his death bed but is nearing it everyday.

I hope to get responses, even if they are not all that useful they help me calm down.

Thanks, Jonathan
