Abstract
A retrofittable submerged terrarium for an aquarium comprising a bottle with a horizontal passageway tube and an upwardly extending access tube with an upper end extending above the water level. Alternatively, two bottles are attached to opposite ends of a passageway tube and an upwardly extending access tube extends above the water level that is attached either to the passageway tube or to one of the bottles. Preferably, an airway tube is provided into a bottle so that air can be circulated freely throughout the terrarium. Brackets are preferably provided to retain the apparatus near the bottom of the aquarium.
