Abstract

Shortly before our class in 10th grade biology was formed, I started preparing a balanced aquarium for the laboratory. In it we have about a dozen small gold fish, several snails, two tad-poles, and a good growth of moss. This aquarium has provided us a great deal of pleasure, as well as many illustrations of life itself.
