Ecospheres:

The ecosphere and the original ecosphere are actually trademark names for blown and sealed glass miniature aquariums. These miniature aquariums are manufactured by the ecosphere associates. This is a company in Tucson which is a place in Arizona, in the United States. These miniature aquariums are mostly spherical or ovoid in shape and are sold across the world as decorative objects or scientific novelties. These miniature aquariums are having a good range of sizes ranging from a base ball size to a soccer ball size. The ecosphere is mainly known for its visual appeal. And the visual appeal lies mainly in the effect provided by the red colored shrimp that is enthusiastically swimming around the radius of the aquarium that is designed by the ecosphere associates. The shrimp is generally a centimeter long. The shrimp consumes the brown coating of bacteria and algae that is present in the glass in the form of a scum. It also consumes the green algae that form a globular pillow on the water and actually perches on a fragment of coral or more precisely soft coral.

 The important and attractive conceptual interest of the thing lies in the fact that these things are a self sustaining biological unit which are able to self sustain for a period of years.
