An aquarium accessory includes a clear dome which is set in place on the habitat floor. The dome has a side opening and at least one top orifice. Air from an aeration system bubbles into the dome through a floor opening, thus creating a dry zone in the dome. Amphibious animals can enter the dry zone and satisfy their need to leave the water periodically, while being confined within the aquarium and remaining fully visible to observers. Air escapes through the top orifice, enabling constant air exchange within the dome. Dry zone volume is varied by adjusting air flow from the aeration system. The dome includes an outwardly projecting flange which enables aquarium gravel to anchor the dome within the aquarium. The flange includes perforations sustaining water circulation, as for filtration, within the aquarium.
