Pacman frog i have had over a year not eating

[TK]

Update: after 14 days of oral doxycycline and warm baths everynight and daily changing of his cage and occasionally carnivore care zeus's redness is gone he doesnt need his cage cleaned anymore hes moving more and more active and for the first time in months hes eating on his own again. He looks so good compared to how he was a bit ago. I kept reading that the medication probably wouldnt work and the vet wont do much for redleg but he seriously is doing alot better. The last thing i need to be sure and for him to go to the bathroom..hopefully soon
