When I woke up this morning and went to mist my frog, I noticed he had a white substance over his body that looked like mold or frost. Is this a fungal infection? If so, what can I do? I can't find anything about this regarding GABFs.

Can't seem to upload the photo I took either, I keep getting an "invalid file" message. Here's a link to the photo:
