Looking for something to put on your desk or in your living room that’ll really draw attention and get people talking? We’ve got just the thing. The EcoSphere Closed Aquatic Ecosystem is basically a little self-sustaining world that you can get on Amazon for as little as $50. These crazy spheres are filled with water, some decorative bits, algae, and real marine shrimp that are actually alive! The shrimp eat the algae as it grows, the algae clean the shrimp’s waste, and on and on the cycle goes. These EcoSpheres are awesome and you definitely need to check one out.

Here’s what you need to know from the product page:

Medium Sphere EcoSphere with turntable base. This fascinating enclosed world contains 7 to 8 marine shrimp, algae and micro-organisms. Made from hand blown glass, each EcoSphere is a completely enclosed, self-sustaining little world. The EcoSphere only needs indirect light and comfortable room temperature (between 60F and 80F.) The EcoSphere works on the basis that a closed system recycles its nutrients and does not produce excess waste. The shrimp consume the algae and micro-organisms and they, in turn, break down the shrimp waste. External light, either artificial or natural, keeps the algae growing. There is no feeding or water changes required. Each EcoSphere comes with a replacement, recharge or upgrade policy.
