The knee joints seems to be deformed/disfigured in that instead of forming a smooth angle between the femur and tibiofibula, they are kiltered up, resulting in the tibiofibula sitting directly above the femur...

It is rather strange looking and I have never seen any of the little guys do this until now (though, I must admit I am rather new to these frogs and have only had them for a few months).

Is it possible that there is no problem at all? It looks quite unnatural to me and, as I said, he also seems less interested in food.

I also forgot to mention in my first post that I occasionally throw in an algae waffer...do these harbor a good source of calcium?

Thanks for the help
