Freshwater fish are easy to care for and provide many opportunities for learning in any classroom. A classroom aquarium is an entire ecosystem in just a couple of feet of space. This ecosystem includes the nitrogen cycling bacteria and photosynthetic algae that form biofilms on the surfaces, protozoa in the filter, aquatic plants, and of course the fish. The fish population provides an opportunity to study animal behavior; from the schooling danio and tetra to aggressive cichlids, each tank offers a chance to study social, feeding, and maybe even breeding behavior.
