Small community Vivarium setup idea

Sometime in the distant future, I would love to tun my 10g into a vivarium, half water half land with live plants and such. My idea was to look something like this picture...but not near as nice and smaller lol, and the land would slope into the water, not be a sharp drop off. I would also like to add a second level that would extend out over the water area to add more surface area for the critters. I was thinking that I would like to stock it with two firebellied newts and 3-5 White Cloud Mountain minnows. They have similar habitat needs for the water part anyway and have been kept together as a successful community by many in a 10 gallon so I know that part will work out. What I am really wondering though is if anything else can be kept in this community setup. I was thinking africandwarf frogs, but they need warmer temperatures so that would obviously not work out. I would really like something that will use the land area a lot. Would manyella frogs work? I know their climate preference is the same, my only concern is them drowning in that water. The edges would be sloped though and have lots of texture so it should be easy to climb out...but I'm still scared they drown. So, any ideas of an animal to go on the land area and thoughts on this setup plan?
