Marimo moss balls are actually not made out of moss at all, but a freshwater green algae. They naturally occur at the bottom of certain lakes of the world where the currents are just right to form this algae into a ball shape. 

Marimo moss balls are a deep green color and are very easy to care for, though extremely slow-growing. They look great in any aquarium and will thrive under low light. Therefore, they are an excellent choice for beginners looking for an easy yet eye-catching "plant" to get into keeping planted tanks.

I usually don’t buy moss balls. There was a scare a few years back of toxic moss balls or something like that. This is the best one I have ever received. It has been a few weeks and it is still healthy! I love Aquarium Co-Op. I wish there was a local store near me.

Marimo moss balls are fantastic...

I have wanted to get some of these in my aquariums for a long time, but have had a hard time finding them in stock in the US. They came in healthy, and my shrimp love them!

Great marimo and very fast shipping

I ordered several marimo moss balls and was surprised that the order was shipped the same day I placed the order! The moss balls were in wonderful condition, packed in a zip closure bubble foil envelope that protected them from damage & made sure they were still cool & moist on arrival. I will be purchasing more from this store in the future.
