Hi there,hope your having a great day,you are looking at our listing of Marimo Moss Balls,come with free moss ball.
We will give you a little bit of info on these little/large green moss balls.
Infact Marimo balls consist of a type of algae (Chlorophyta) that grows in a spherical shape because of water currents. They can naturally be found in lakes in cold areas like Japan and Iceland,here in scotland where they grow in large “colonies” on the lake/loch floor.
Marimo balls are easy to care for and beginner-proof. Because of the cold temperatures they are grown at they are great in any tank or vase for a goodluck charm as that's what they have been used for in Japan for years.
To keep the marimo as healthy! It’s a good idea to pick up your marimo moss ball once in a while (especially if dirt particles have accumulated on it or if the green has turned a bit brown or greyish) and gently wash it by squishing it a few times in a container with some clean water. And your good to go.
There is a few fish that they may not mix well with which is , Plecos and goldfish because both fish love to eat green algae. But it all comes down to the fish itself as they have been know to be OK through personal experience of my own. 
An interesting note about the marimo moss ball is that it can actually be kept in a brackish water tank. It is noted on various aquarium plant websites that it is able to thrive in waters with a salinity up to mid-end brackish.
