I never see her sit in the water bowl, ever. But like I said, her skin seems just fine to me, so maybe she's soaking when no one's looking? I'm not sure. And, these guys never bite at each other or show aggression in any way. The "worst" thing that happens is when they sit on each other, or when two are trying to squeeze into the same spot in the bamboo tube in which they sleep during the day, and they croak out of annoyance. But that's it.
