Sick Whites Dumpy Tree Frog, any hope?

[smashley]

okay! Here are a couple of shots from just now. Do you know how long they can survive without eating?
He has been sort of puffed up for a day or so now, he was pretty bony looking a couple days ago (and he hasn't eaten since then). He is probably 1.5-2 inches long, nose to butt. How often can I put him in a 10% pedialyte/90% dechlorinated water bath? I was advised to leave him in for about 20 minutes, can I do this daily while he is recovering?
