Pictured is a low tech, freshwater aquarium. This particular tank has no mechanical filtration system - only live plants are used for filtration. It does use fluorescent lighting, in addition to the natural lighting it receives from the west facing window it sits in front of. A heater is also used during cold months. Very little care is provided for this tank (which has many different species of freshwater fish), except to feed the fish and add water to the tank as needed. (Water changes are done infrequently, removing particulate/ detritus from the substrate.) The Cardinal Tetras (Paracheirodon axelrodi) ) shown here are native to South America. They live in slow moving waters, so they are perfect for this low tech tank. They do best in softly, acidic water in groups of six or more.
