Claim:
A vivarium assembly for creating separated wet, moist, and dry environments within an aquarium tank, the vivarium assembly comprising: an enclosure comprising: at least one sidewall defining a vertical height and a longitudinal length between a back end and a distal front end forward of the back end, a laterally extending dry wall sealingly attached to the back end, and a laterally extending dividing wall spaced forward from the dry wall and sealingly attached to the at least one sidewall, thereby defining a wetland area that is between the dividing wall and the dry wall, and an aquatic area forward of the dividing wall; adhesive for sealingly attaching the enclosure to one or more walls of the aquarium tank, thereby completing the enclosure such that the aquatic area and the wetland area are contained and separated from a dry land area in a remainder of the aquarium tank; 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; and an organic filter in the wetland area, the organic filter comprising a living wetland plant rooted in a porous growing medium such that water circulating through the water passage carries animal waste from the aquatic area into the growing medium where the plant can absorb the waste as fertilizer which it converts to oxygen.
