Abstract
A transparent housing having top, bottom and side walls contains plant or animal life in a habitat which is submerged in an aquarium. A forced air pump is connected by a tubular conduit to the housing for introduction of air into the housing. Perforations in one wall provide means for passage of air out of the housing and, when air pressure is reduced, permits water to flow into the habitat to provide nourishment to the life contained therein.
