You have documented some of the features of the final impact well in your series of images. Infected frogs: - discoloured skin; peeling or sloughing of skin, particularly on feet; or roughness of skin; sitting out in open, not protecting itself or hiding; sluggishness; no appetite; legs spread slightly away from body, rather than tucked in; body becoming rigid with back legs trailing behind. Emaciation, dehydration, mummified. I have some important information if you want to know what to do if you find a dead or infected frog. Message me and I'll give you details. I'll also contact the admin. to advise a notice should be put up if people are finding these infected frogs and how to deal with them.
