Forget about Sea Monkeys and Goldfish; the EcoSphere Closed Aquatic Ecosystem is way more than just a pet, it’s an entire miniature world in your hands! Each EcoSphere contains living micro-organisms, marine shrimp, algae, and bacteria. It’s completely self sustaining, so you never need to feed or clean it! All it needs is a source of light: indirect, natural, or artificial. EcoSphere is both a scientific breakthrough and a piece of living art. The average lifespan for each EcoSphere is about 2 to 3 years, so you’ll enjoy this self-sustaining masterpiece way longer than the poor goldfish you won at the carnival…

They seem cool at first… until you realize the shrimp inside are capable of living decades. They die in a few years in these globes not because it’s a self-sustaining environment, but because it takes a long time for them to starve to death and they have a high tolerance for water toxicity. It’s much less cool when you know that.
