I have kept a few frogs over the years, so I know that what I'm seeing and feeling isn't normal... or at least doesn't seem normal to me.

One of my frogs have a sticky skin, rather than wet froglike skin. It's sticky in a way that will end up on my hands and it makes the substrate stick to the skin as well, making the frog look dirty and dark. The frog is a Kaloula pulchra, hopefully female, and is the only one of any Kaloula I've kept that has this kind of skin. None of my red banded rubber frogs have that kind of skin, not even my false tomato frog. I've never seen it in any of the wild Ranids here in Sweden either.

I thought it might go away, but I've had her over a year now, and she is eating fine, looking good otherwise, but the skin is still sticky.

Has anyone ever seen this on any kind of frog? If so, what is the cause and is there a treatement?
