Taxiphyllum barbieri – Javamos

Taxiphyllum barbieri of Java Moss by its common name is a very strong undemanding plant. They will do fine in most water and lights. This moss will grow on any surface and is ideal to decorate rocks and wood or to hide your equipment with.

Previously the scientific name was Vesicularia dubyana but is now to be believed Taxiphyllum barbieri.

Formerly the scientific name was Vesicularia dubyana but that has changed to Taxiphyllum barbieri. This change is still controversial. Some say Vesicularia dubyana is a different type of moss (Singapore Moss) and other scientists believe it to be one species.

Synonyms: Isopterygium barbieri, Vesicularia dubyana.


Javamos has delicate little stems that are covered with minuscule small overlapping oval leaves. The underwater (submerged) form has finer branches than the upper water (emerse) form. Like other moss species, they do not really have a root system. Brown hairy Rizoids grow on the underside, which ensure the anchoring of the moss to the substrate. Over time, it can attach itself to wood, stone but even on glass as long as it was previously covered by algae.

The Java Moss stems can reach lengths of about 3 to 10 centimeters, depending on circumstances. The water values are not very important, at a temperature of 15 to 28 degrees, pH of 5.5 to 8 and low light the moss will usually grow.

It is important to keep the moss clean. Because it is so delicate, dirt will easily accumulate. Use your fingers regularly to shake any dirt out of the Java Moss. You do not have to be too careful, Javamos is delicate but relatively strong.

Origin and distribution

Java Moss originates from Southeast Asia and is found in the Philippines, Indonesia, Japan, Malaysia, Singapore and Vietnam. It grows frequently in humid places, mostly above water on rocks, fallen tree trunks and along the banks of rivers and streams.

Java Moss in the Aquarium

You can easily attach Javamos with a piece of fishing line until it has attached to the substrate. You can even attach it to a fine grid or mesh to create a complete moss wall or carpet. Just put the moss between two layers of gauze, the moss will naturally grow in between.

Java Moss pruning and propagation

If it starts to grow too exuberant, you can prune Java Moss with scissors. If you have a bit longer pruning, you can use it again to plant in a different spot. Just tie it to the surface where it will grow out to be just as nice as the originating plant.

In breeding aquariums Taxiphyllum barbieri – Javamos is an excellent hiding place for eggs and fry. For example, it is frequently used in the cultivation of Killifish.


Javamos is also an excellent choice for the Paludarium. It can be used for the background or bottom. Make sure that it is processed in a moist place.
