The world’s first totally enclosed ecosystem – a complete, self-contained and self-sustaining mini world. The eco-sphere contains algae, micro-organisms and marine shrimp and is completely self sustaining. You never have to feed the life within. Simply provide your EcoSphere with a source of indirect natural or artificial light and enjoy this aesthetic blend of art and science, beauty and balance. EcoSpheres have an average life expectancy of two years. However, it is not uncommon for shrimp populations to be thriving in systems as old as 7 years. Learn more here.
