Well with a small tank frequent water changes should be no problem. What If I did a asian rice patty biotope? Planted the tank pretty densely with rice plants and just put a couple of a shrimp or one crayfish native to that area. Do you know of any one having any experience doing a set-up similar to this?

But what is known is that the more plants, and fewer fish, the more self-maintaining an aquarium can be. It can be filter-less. A heater and overhead light may be all the equipment needed. I ran a 10g with no filter and no light for several months as an experiment. The light was problematic, as the plants naturally grew toward the light source, being the window. And the lack of a filter did mean the water was not crystal clear. But some small (dwarf-type) fish, shrimp, snails, and thick with plants did work. I still did weekly water changes of half the tank, and I would not recommend anything less. The difference this makes to the fish cannot be ignored.
