Hi,

You know that convulse/flex/tensing sort of thing they do when they pee? I've recently noticed them doing it repeatedly while sitting in their water dish (probably not a new thing, probably a sign I've spent too much time watching them with a weak flashlight at night recently). I can't tell if anything is coming out, but the convulsing kind of motion is the same. Is this some kind of water exchange?

At first, I thought it was one frog being rude to another in the dish, but some kind of exchange seems more plausible. Note mine don't poop in the water, and that would be a better way to get the dish to yourself.
