Good luck! I'm sure he'll be just fine with a bit of TLC. You did the right thing taking him to the vets, so many people put it off because its 'too expensive' or whatever and its always the animals that suffer. One of the problems with exotics is they often dont show their symptoms, or at least obvious ones, until their quite far progressed with it. I know i'm always on the look out for the slightest bit of redness in my tree frogs! paranoia is healthy!
