The Ecosphere is a sealed globe containing algae, shrimp, and gravel. You control the temperature and the amount of light it receives, otherwise, the system can sustains itself for several years! An abrasive magnet can be used to clean the inner surface, if neccessary. Useful as a learning tool or as a very low-maintenance pet. Link -via Dump Trumpet

I got this for my daughter in May of 05 and they are still doing well, though all we’ve done is let it sit on our kitchen counter. The critters are a lot like sea monkeys, but pinkish and a little larger.

They are not Sea-Monkeys. Me… being the former webbedmaster of SeamonkeyMania.com can say assure you of this. Most folks aren’t able to get Sea-Monkeys to live past 6 months.
I do however, have an Ecosphere myself which I purchased in December of 2001. Of the three shrimp inside, I still have one that’s still alive and kicking. When that one dies, the Ecosphere people will “re-charge” the sphere with new algae and shrimp for a nominal fee.

I have an ecosphere that is 9 years old. It originally came with 3 shrimp, but two died in the first month. The third is still quite active.
