Hi! Your post is a bit old now so I don't know if this is relevant but you might try the people at the pipidae.net forum there seem to be quite a few pople on there that know quite a bit about the clawed frogs. Also, the people from growafrog.com (they sell those kits where you get a ACF tadpole) say on their website that they have a certain food that they sell for frogs that contain an antibiotic. Don't know if they will sell to people unless you can prove that your frog came from them but it may be worth a shot if it will save your froggies life.
