Abstract: A vivaria assembly for separating aquatic animals and plants from terrestrial animals and plants includes a container and a set of panels. The panels are engaged to the container and positioned in an interior space defined by the container. Each panel extends from a bottom to proximate to a top of the container so that the container and the panels define a plurality of compartments within the interior space. The panels and at least a portion of a wall of the container are substantially transparent. A plurality of cutouts is positioned in the container so that each compartment has at least one cutout permitting access to the compartment. A respective habitat element and at least one of an animal and a plant can be inserted into each compartment to create a respective vivarium within the compartment.
