Created by Alliah of Etsy store Marimo in a Bottle, the Miniature Fingertip Aquarium is quite possibly the tiniest aquarium on the face of this planet.
This ring is a tiny vial that sits on your finger, looking like something a witch or holistic doctor has concocted to preserve your youth. You may be asking yourself, what kind of aquatic creature could possibly fit into this miniscule aquarium? The answer is a live marimo ball, which is a rare form of algae that is native to Japan. Marimo is the perfect name for this soft ball-shaped plant as it actually means "bouncy plant."
You can get the Miniature Fingertip Aquarium vial comes in a cylinder shape or a more rounded shape.
