Our Review

See, the thing with getting an aquarium, it doesn’t really stop at just an aquarium. You’d have to get lights and filters and décor and the actually fish just to start you off. And then for the remainder of its life, you’d have to periodically clean the tank and feed the fish and a whole other stuff having a pet entails.

That’s what makes the EcoSphere Closed Aquatic Ecosystem very attractive, other than the obvious.

According to its product description, it’s the world’s first enclosed ecosystem, meaning it’s complete, self-contained and self-sustaining. It’s a whole marine world totally enclosed in glass.

The sphere already comes with active micro-organisms, some small shrimp, algae and bacteria in filtered sea water. You won’t have to feed the shrimp. All you need is ample lighting and it’s good for another 2 to 3 years.

You’re probably thinking there’s no way that little aquarium will stay clean for 3 years and you’re actually right. Film will form in the inside of the glass because of the micro-organisms in there.

It’s not really harmful to the inhabitants but it makes your little sphere look dirty. But cleaning it is easy because magnets have been installed inside the unit. By using the magnet supplied with the handbook, you just let them attract each other and drag the film away.

The EcoSphere we had was purchased on a whim, really. We already have a nice 75 gallon aquarium set up in the living room and I was just hoping to get a small one for my home office. Something to place on the desk. I saw the EcoSphere while browsing through round aquariums at Amazon. I was actually happy that it came complete – no need to mix or install anything. The shrimp were a nice change to our usual fishes.

The glass appears to be durable. But it is glass so I was never really inclined to test out just how tough the material is. It might be smart to keep the sphere away from smaller children, though. Or if you’re really worried about the whole thing just rolling over, then check out the version that’s more ovoid.

Just a word of caution: if you’re planning to give this to anyone as a gift, make sure it’s opened and placed under a light source immediately. The shrimp need the algae to grow and no light shrinks them.


  • Easy to care for.
  • Complete set up.
  • Pretty to look at.
  • No need to feed aquaria.


  • Quite distracting to have on your desk.
  • May not be as sturdy as the picture looks.
