Etsy user alliah made this unique miniature fingertip aquarium ring, which contains a type of live algae, called a marimo ball, in a small vial that is mounted on a ring band.
Mari means bouncy ball and Mo is a term for plants that grow in water. So, marimo means bouncy plant. People often mistake them for living animals because they are usually moving around in the tank. Your marimo friends will grow in tap water at room temperature as long as the water is changed every one or two weeks…All they need is normal household lighting for them to make food, otherwise, indirect sunlight is fine.
