The EcoSphere and "Original Ecosphere" are trademark names for sealed blown-glass miniature aquaria produced by Ecosphere Associates, Inc., of Tucson, Arizona, United States.

Where does the ecosphere get its energy?

The EcoSphere works by gathering energy from the light and converting it biochemically. Light, together with the carbon dioxide in the water, enables the algae to produce oxygen by photosynthesis. The shrimp breathe the oxygen in the water and graze on the algae and the bacteria.

How long can EcoSpheres last?

The average life of an EcoSphere is between 2 and 3 years. The life expectancy of these shrimp is known to exceed 5 years, and the oldest EcoSpheres are now over 10 years old and still going strong.
