Due to its hardy nature, strong growth, and low requirements for different conditions, Java moss is very easy to care for. It is often used to decorate rockeries or aquariums.</span></p> Besides, Java moss is widely used as a substrate for breeding fish. Fish eggs will attach to Java moss, making it a perfect breeding method for fish. In Killi fish breeding facilities, a clump of Java moss is placed in the Killi fish tank, and after a week, it will be covered with Killi eggs. Many people refer to Java moss as fish breeding moss.
