ABSTRACT:
A container, having a sealable closure, has included therein distilled water, one or more aquatic plants, one or more herbivorous fish, an aquatic algae eating animal, inert particulate material and measured amounts of certain elements. The elements are nitrogen, potassium, phosphorous, calcium and magnesium. An air space is left at the top of the container and a pinhole provided in the closure. This shelf perpetuating, sealed aquarium requires no air pump or heater, and fish food is not added; however, sufficient light to maintain the aquatic plants in healthy condition is necessary.
