Abstract
The closed-type aquarium of the present invention includes a light transmissive container in which a vapor phase of air and a liquid phase of water are sealed. The liquid phase includes a shrimp, an aquatic plant and a microorganism. Further, to enhance efficiency of material recycling, the liquid phase includes a snail that has a different ecological niche than that of the shrimp and a plant dead body that supplements a resource essential for photosynthesis of the aquatic plant.
