A floatable aquarium accessory formed to resemble a natural rocky shoreline setting. The invention provides a stable, landscapable, and functional terrestrial surface within the aquarium into which it is inserted. It moves vertically in response to changes in the water level of the aquarium while lateral movement in all directions is restricted by close contact with the interior side walls of the aquarium. The invention conceals the aquarium's water filtration system within removable enclosing members which also resemble natural rock formations. Additionally, it supports the system at the proper position in relation to the water level of the aquarium for its normal operation. The upper terrestrial surface containes a number of depressions for holding aquarium gravel and terrestrial plants. The outflow of water from the water filtration system may be diverted over its enclosing formation. This creates a simulated waterfall which serves as a point of interest for the terrestrial setting while enhancing the aquatic scene below.
A device which divides an aquarium into an upper terrarium compartment and a lower aquarium compartment comprising a floatable structure inserted into said aquarium, and having exterior peripheral walls which are in slidable engagement with a plurality of interior lateral walls of said aquarium, said exterior peripheral walls of said floatable structure having sufficient height and simultaneously engaging a sufficient number of said interior lateral walls of said aquarium to prevent said floatable structure from tipping or moving in any lateral direction while permitting said floatable structure to move vertically in response to fluctuations in the water level within said aquarium, said floatable structure serving as a stable and non-tippable terrestrial base for said upper terrarium compartment.
A device which divides an aquarium into an upper terrarium compartment and a lower aquarium compartment comprising a structure inserted into said aquarium, and having an exterior upper surface which serves as a base for said upper terrarium compartment, said structure having means for containing and concealing aquarium accessory devices used for controlling conditions in said lower aquarium compartment within said structure, and using an outflow of aquarium water from a water circulating device contained within said structure to produce a waterfall, cascade, or a similar scenic effect within said upper terrarium compartment.
