Description
Overview: Java Moss is arguably the most common and easiest plant in the aquarium hobby. It can grow in almost any light and water conditions. It doesn’t have true roots but instead attaches itself to any surface. It is a favorite for breeders as it provides excellent cover for fry and shrimp. It can be used to cover driftwood, stones, or even to create a "moss wall" at the back of the tank.
