Pixie Frog Injury or Fungus?

[louie71]

I can't figure out if this is an injury, fungus or what? He's active and gobbling up food as usual, but this appeared about a week ago and seems to be getting worse. I noticed it after I had put him in his outdoor enclosure that I keep him in during the warm part of the year. I live in Phoenix. It's a shaded outdoor habitat. After several years I've never had any issues until now. I now have him indoors in a sanitized aquarium with moist paper towels I change out everyday until this heals or I can figure out what the situation is. I am worried whatever this is could spread to his eyes as it is close to that area. Any advice would be greatly appreciated. Thanks!

I can't get any of my jpegs to embed or attach. There within the dimension parameters. The only way I can get close is to drag and drop in FireFox and I can see the image in my draft, but when I post it disappears.

The best I can do is provide this link for the pic. http://1drv.ms/1D54uu7
