I am asking for your opinions, and notice how I wrote "debate" in the title. This means I would like to argue lol. Friendly arguing of course. I'm not trying to prove this is a better method, but just possibly prove it is just as good as any other. I know it seems to be frowned upon to use water, and I'm personally puzzled by this that's all. I've always been good for asking "why" and that's simply all I'm doing here. No need to get bent out of shape over a debate over substrate.

1.) Sorry if I wasn't clear as to how much water. I would never put them in a tank of water filled to the top or anything of the sort lol
2.) Are the species that much different in terms of body make up? I'm still a big newb with the difference in species, and didn't know they look that much different or have a different body structure that would alter swimming from species to species. If so please fill me in :]
3.) I'm not saying there's anything wrong with using a water dish and doing what your doing. All I'm trying to get across in this post is that water as a main substrate might be suitable for them.
4.) I found this kind of funny in your post. "We have tried all kinds of different setups to see what they were most comfortable with, because in the end, the frogs are what matter, right?"- This is why I am making this post in the first place. My frog seemed to be quite at home in the water. Therefore I would like to offer a lot of it because he used it 2:1(water/land). This is what my frog seems to prefer and he's what matters. I'm comfortable keeping him in whatever he prefers simple as that.
