Java Moss: Frequently asked questions

What types of Java Moss are there and what determines a good product?

Java Moss is actually a type of aquatic moss. There are many different varieties, but the most common ones found in aquariums are Vesicularia Dubyana and Vesicularia Montagnei (Java Fern). These two types have very similar characteristics, so for all practical purposes they can be considered to be one species. The only difference between them is that V. dubyana has longer leaves than V. montagnei .

The good Java Moss is the one that has a lot of leaves and branches. It should be green in color, not yellow or brownish. There must also be no black spots on it as this indicates contamination by fungi which will cause your fish to get sick if you put them into an aquarium with such moss.

Who should use a Java Moss?

Java Moss is a great plant for beginners. It’s very forgiving and easy to care for, so you can learn the basics of aquarium keeping without worrying about killing your plants. Once you get more experience with planted tanks, it makes an excellent addition to any tank because it helps keep algae at bay by competing with algae for nutrients in the water column.

Based on what criteria should you buy a Java Moss?

If you are looking for a low-maintenance plant that can survive in low light conditions, Java Moss is the one. It does not require any special care and will thrive even if it’s left unattended for days or weeks at a time. However, if your tank has high lighting levels (such as those used to grow live plants) then this moss may die off because of its inability to photosynthesize under such harsh conditions. The best way to ensure healthy growth is by keeping the water temperature between 68°F – 78°F (20 °C – 26 °C).

The most important thing to look out for is the color of your Java Moss. If it’s not green, then you can be sure that what you have in front of you isn’t a real Java Moss. It might be some other type of moss or even an algae. Another thing to check when comparing different types of java mosses is their size and shape as well as how they are attached to rocks or driftwood pieces.

What are the advantages and disadvantages of a Java Moss?


Java Moss is a very easy plant to grow. It can be attached to rocks, driftwood or any other object in your aquarium without the use of glue and will stay there until you decide to take it off. This makes it ideal for beginners as well as advanced aquarists who are looking for an alternative way of decorating their tanks.


Java Moss is not a plant that can be used as the main focal point of an aquarium. It does well in tanks with other plants, but it will never look like a forest or jungle. Also, if you are looking for something to cover your tank’s background this might not be the best option either because it grows very slowly and requires high lighting conditions which most people do not have at home.
