An Ecosphere is a little sealed glass container that contains live shrimp. It is a self-sustaining aquarium in that the shrimp take a dump, algae feed on sunlight and the nutrients from the dump, and finally the shrimp eat the algae. My father-in-law got me an Ecosphere as a Christmas present, which I took to work about a month ago to use as a cool desk ornament. I come back from lunch today only to find this note that one of my co-workers stuck to the front of my Ecosphere:
I am such a horrible person
The Shrimp Killer sign refers to the fact that I have killed all but one of the four shrimp that came in the Ecosphere. Clyde, the smallest of the quartet, is the sole survivor. Inky, Blinky, and Pinky were not so fortunate. The florescent light above my desk stays on 24/7. I knew this and just neglected to cover the Ecosphere before I left work each day. My guess is that the Ecosphere received too much light and the balance of algae and bacteria in aquarium was offset. So, yes, I am a ghastly, wicked, cold-blooded Shrimp Killer. At least Clyde had a few great meals. He had no qualms about eating the rotting carcasses of his fallen brethren.
