EcoSphere Closed Aquatic

World’s first totally enclosed ecosystem utilizing NASA technology. Unique gift item, perfect blend of science and art. A contained, balanced environment made of glass, the EcoSphere. Shrimp, algae, and other saltwater-based creatures can be found inside each EcoSphere. You never need to change the water or provide food for the life inside the EcoSphere because it already has all it needs to survive. A source of light and a reasonable room temperature (between 65 and 80 F) are all that are required.  It is good housewarming gifts for guys
