Java moss is one of the most popular plants used in vivariums, due to its hardiness, versatility, and ease of care. But can it really live out of the water, and if so, how? Read on to find out.

What is Java Moss?

Java moss (Vesicularia dubyana) is a small, low-growing aquatic plant native to Southeast Asia. It is hardy and easy to care for, making it a popular choice for vivariums. The plant has tiny, green, fan-shaped leaves and grows in a creeping, carpet-like pattern. It is commonly used to decorate aquariums, terrariums, and vivariums, and is especially well-suited to paludariums and ripariums, which combine land and water features.

Can Java Moss Live Out of Water?

The short answer is yes, java moss can live out of water. However, it is a semi-aquatic plant, meaning it needs a certain amount of moisture to survive. It cannot survive in a completely dry environment, and if the conditions are too dry, the plant will die. The key is to find the right balance of moisture and air. If the vivarium is too wet, the plant will not get enough oxygen and will suffer from root rot. If the vivarium is too dry, the plant will suffer from dehydration.

How to Keep Java Moss Alive Out of Water

To keep java moss alive out of water, the vivarium must be kept moist. The best way to do this is to mist the vivarium daily with a spray bottle. Alternatively, you can set up a misting system that will automatically mist the vivarium. The water should be filtered and free of chlorine and other chemicals. The water should also be at room temperature or slightly cooler.

What Conditions Does Java Moss Need to Survive?

Java moss needs adequate light, moisture, and air to survive. It should be kept in an area with indirect sunlight or artificial lighting. The light should be strong enough to reach the bottom of the vivarium, as java moss needs light to photosynthesize. In terms of humidity, the vivarium should be kept between 60-80%. This can be achieved by misting the vivarium daily and by keeping the air circulating.

Can Java Moss be Grown Out of Water?

Java moss can be grown out of water as long as it is kept moist and in the right conditions. The plant can be attached to rocks, driftwood, or other decorations in the vivarium. Once the java moss is attached, it will start to spread and cover the decoration. The plant can also be grown on the ground or in a pot filled with aquarium soil or sphagnum moss.

Advantages of Growing Java Moss Out of Water

There are several advantages to growing java moss out of water. For one, it is very easy to care for and requires little maintenance. Once the moss is established, it will start to spread and can easily be trimmed back if it starts to get out of control. Additionally, the plant provides a great hiding place for fish, frogs, and other creatures in the vivarium.

Disadvantages of Growing Java Moss Out of Water

The main disadvantage of growing java moss out of water is that it can be prone to drying out if the vivarium is not kept moist. If the plant dries out, it will not survive. Additionally, if the humidity in the vivarium is too low, the plant may start to turn yellow and die. Finally, if the plant is not kept in the right conditions, it may become infested with pests.


Java moss can indeed live out of water in a vivarium, as long as the right conditions are met. The vivarium must be kept moist, with adequate light and air circulation. The plant can be attached to rocks, driftwood, or other decorations, or it can be grown on the ground or in a pot. While it is easy to care for, it can be prone to drying out if the conditions are not right, so it is important to monitor the vivarium closely.
