Imagine the opportunity to create a miniature ecosystem in your classroom. An omnarium is a sturdy acrylic pod in which plants and animals are placed and sealed from the outside world. A wonderful opportunity for studying the balanced symbiotic relationship between plants and animals in a closed system. Access to this miniaquarium (for removal of materials or feeding fish) is through a removable plug. The entire unit is on a rotating base. Low- to medium-light levels, room temperature, occasional water changes, and periodic feedings are needed to support this semiclosed system. Each kit includes an omnarium with rotary base, gravel, plug, cleaning tool, fish food, water conditioner, and funnel. Also includes aquatic plants, snails, and 2 small fish. Size, 5 1/4" H.
