Skin and Bones African Dwarf Frog

[Nippyfish]

My friend's African Dwarf Frog has quickly lost weight and is now described as "skin and bones" and "frightening" in appearance. It is still acting normally and is eating fine and receiving plenty of food. She is at work and unable to check the parameters at this time but is not new to the hobby and keeps her tanks well maintained. (tests regularly)

My first instinct was that it might be a parasitic infestation but neither her nor I have treated a frog for this before.

Does anyone have any idea what could cause this deterioration? There is another ADF in the tank that is still perfectly healthy.

Thanks,
C
