An aquaponic housing unit fits over standard aftermarket aquariums. The system utilizes the natural symbiotic relationship between fish and plants to achieve adequate filtration for the aquarium below. A large planting container is elevated over the aquarium by two support legs so that the planting container is larger than the aquarium. The support legs can be used to hide wires or control boxes, along with using the legs as storage compartments or additional planting area. An aquarium pump delivers water to the planting container so that fish waste can be used as nutrients for plants in the container. The nitrogen cycle transforms the fish waste into useable nutrients for the plants, thus cleaning the water for the aquarium. The system can be used as a learning tool for students of all ages. It also creates a low maintenance, self-watering and self-fertilizing garden.

Container for aquatic plants, which can be filled with water, the side walls and bottom of which comprise an outer wall and a bottom wall, respectively, in each instance, followed, toward the interior of the container, by an intermediate layer that consists of an insulating material. On the inside of the container, the insulating material is completely covered with a water-tight plastic film, in the manner of a tub, or by a water-tight basin composed of transparent glass. On the bottom of the tub or of the basin and/or in a plant pot situated in the container, there is a plant culture medium that makes growth of aquatic plants possible, and preferably winter-hardy and/or non-winter-hardy aquatic plants are disposed in the container, which is filled with water.

The invention relates to a water inlet arrangement for the use in fish tanks in aquaculture, including a pipe to feed water into the tank, the pipe having a plurality of openings and, for a better adjustment of the flow, a surrounding second element having a plurality of openings and/or a fixed or adjustable shield are provided.

An example aquatic imaging system comprises a light source, a first platform coupled with a image capture device and a second platform that is parallel to the platform, the image capture device having a first field of view, and, the second platform being coupled to a organism tank, first organism tank having an inner wall, outer wall and a base that defines a well capable of retaining water, the base being parallel to the second platform, the organism tank configured to receive a light beam originating from the light source and configured to project at least a portion of the light beam through the well and in a directional plane that is parallel to the base, the image capture device configured to direct the first field of view from the first platform through the well in the organism tank.

An apparatus for dividing an aquarium into a plurality of compartments includes retainer assemblies and a divider. The retainer assemblies each have a retainer member and a base member, and the base member is removably attachable to the aquarium. The divider is positionable between retainer assemblies and has at least one opening allowing for fluid communication between compartments. A method for dividing an aquarium into compartments includes affixing retainer assemblies to locations in the aquarium, positioning a divider between the retainer assemblies, and connecting the divider to the retainer assemblies.

Modular habitat structure (MHS) which can accommodate one or more live inhabitants is comprised of a rigid pillar which extends linearly away from a base end toward an upper end. A plurality of major system components are disposed at different locations along a length of the rigid pillar. Each of the major system components is comprised of modular segments which individually extend circumferentially around at least a portion of the rigid pillar. The modular configuration of the segments allows user configuration of the MHS by selectively adding or removing one or more segments of each of the major system components.

The invention provides compositions that increase the mobilization, homing, expansion, and/or differentiation of stem cells and methods of using the same for the treatment of mammals.

Disclosed is an aquarium lid. The aquarium lid comprises a lid body made of a transparent rigid material, wherein the shape of an outer edge of the aquarium lid is designed to have a shape adapted to the edge shape of a mouth of an aquarium, and the lid body is further provided with a plurality of shaped bumps, planar regions, through-holes, and edge notches; at least one shaped platform is formed at a top surface of the shaped bumps and/or between at least two shaped bumps. This disclosure also provides an aquarium having the aquarium lid with shaped bumps. The provided aquarium lid with shaped bumps, planar regions, through-holes, and edge notches and the aquarium having the same are simply structured and exhibit aesthetics that meets different demands of viewers.

Disclosed is an aquarium ornamental device. An aquarium ornamental device comprises a compressor configured for compressing inlet air, a multiport valve that is electromechanical or mechanically actuated, a plurality of pipes, and an expandable-and-shrinkable member having at least one one-way valve; the compressor, the multiport valve, and the expandable-and-shrinkable member are connected one another in sequence by means of the pipes; the compressor and the multiport valve are placed outside the aquarium, and the expandable-and-shrinkable member having the one-way valve is placed in the water contained within the aquarium.
