Thank you so much for your help. I have him in a 20 gallon. Have not separated the frogs. His buddy is doing well. I can't get a good pic of him, but he basically looks like a blown up balloon, getting worse every day. I have been doing the salt baths, and over two days completed a 100% water change. I have a whisper filter for 20 gal tank. Just wondering if there was anything else I could do. Also if I would see any change for the better before ten days. I'm just very concerned because while I am providing him with fresh water and salt baths, he continues to get worse.

P.S. He is natural colored, not albino, and I noticed since we got him that his skin seems pale. Would that be considered discoloration? Should I purchase antibiotics? Thank you!
