This may be a stupid question but I see people stressing how sensitive frog and toads' skin is. If I needed to move my frog to clean the tank, or move him to a different feeding area how should I go about washing my hands? I have heard that you should not use soap because if any is left it will damage them badly. But then your hands would be dirty. Like I said, maybe I'm over thinking, but I am new to frogs and want to have the best starting experience possible!
