Java moss (Taxiphyllum barieri) is a great plant to include in low-light aquariums holding small tropical freshwater fish.It is one of the easier plants to grow, tolerates a wide range of temperatures, and will happily grow in just about any substrate or attach itself to any surface. Almost impossible to harm, Java moss is a favorite of many popular freshwater tropical aquarists.
Java moss is native to tropical regions of Southeast Asia. It grows on forest floors, tree trunks and along river banks.
Java moss really doesn’t need fertilizers to grow well. It will grow faster if you use fertilizers, but frankly, it already grows pretty fast all on its own. Since Java moss doesn’t have roots, the best fertilizers to use are liquid additives that go into the water column.
It grows best at 70 to 75° Fahrenheit (21 to 24° Celsius), but can live in temperatures of up to 85 to 90 °F (29 to 32 °C).
