Having discovered that I can maintain a closed ecosystem in a jar indefinitely (by which I mean for three weeks; I have the time-sense of a hyperactive Chihuahua), I decided to try a slightly riskier endeavor. Using a high-grade sterile enclosure cleverly disguised to look like an old curry jar, I added sand, gravel, crushed seashells, conditioned tapwater, and one Malaysian trumpet snail (Melanoides tuberculata). I chose the trumpet snail because: 1) I had some on hand, which the petstore (somewhat forebodingly) gave me for free; 2) They’re a lot smaller than my big aquarium snails; and 3) They’re apparently tough as hell and don’t have much in the way of oxygen demands. For oxygenation, I added four or five fragments of a Marimo moss ball plant I bought about a week ago. Here are the results:
In case you couldn’t tell from my wonderful photography, the plants are in the middle and the snail is that little brown thing half-hidden by a reflection off to the left. Surprisingly, the water isn’t cloudy because of my incompetence, but because the crushed seashells haven’t had time to settle yet, and I’m apparently harboring some latent anger, because I crushed them really well. More updates as events warrant!
