Abstract: A vivarium and assembly for maintaining an aquatic area, wetlands, and dry land. The assembly is an enclosure for adhering to a transparent sidewall of an aquarium tank to provide sidewalls, a dry wall and a dividing wall positioned between the dry wall and the aquarium tank wall to define an aquatic area by the aquarium tank wall and a wetlands area by the dry wall. The enclosure can be surrounded by dry land area. A filtering system includes a water passage between the aquatic area and the wetland area; a water pump connected for pumping water out of the wetland area and back into the aquatic area; a particulate filter between the wetland area and the pump; and an organic filter in the wetland area, the organic filter being a living wetland plant rooted in a growing medium.
