Water bowls for mature pixie frogs are optional!

When she is not burried, my girl spends half time in water bowl and half time on substrate.
She also often poops in water.

I must say when I first read the post I thought it is a joke lol then I read the whole thread and then re read the first post again lol
You are not kidding are you? Well... If it works for you it is great, if you don't have any problems it is awesome! If you won't have any problems after a few years it is even better.

But.... Most of the frogs don't eat in a separate container and don't poop/urinate here as well, so most will go in a substrate and are gonna sit in all that unless you change it every single time. or parts of it, although i doubt it will not stink if a frog poops in muddy substrate and you change just part of it. Constant muddy substrate is a an excellent media for all sorts of stuff: Protozoa, bacteria, fungus and so much more...
Frogs in a wild have a choice to go into the water or burry into the substrate, your set up will limit their choices. My girl for example sometimes sits with just eyes sticking out of the water for days and then sits burrowed into substrate.

sometimes things work out for one frog but don't really for others, and when recommending something I much rather look from all perspectives and avoid anything that might be dangerous. Having said that like or not , having time or not to change water every day I'd rather do it then not. It is always better be safe then sorry. Too many things might go wrong otherwise and I don't want to take chances nor advise anyone on doing so.
