Java Moss

[Mugwump]

Java Moss is a moss belonging to the Hypnaceae family. Native to Southeast Asia, it is commonly used in freshwater aquariums. It attaches to rocks, roots, and driftwood. The identity of this well-known plant is not resolved; formerly thought to be Vesicularia dubyana (Brotherus, 1908), it may actually be Taxiphyllum barbieri.[1]

Java Moss does not require any special attention. It accepts all kind of waters, even weakly brackish, and all kind of light qualities. It grows best at 70 to 75 degrees Fahrenheit (21 to 24 degrees Celsius), but can live in temperatures of up to 85 to 90 ?F (29 to 32 ?C). It is a low light plant and makes a great foreground plant. In aquariums it should be planted where there is good water current because debris gets stuck on it easily and gives it a brown fuzzy appearance. Due to its clinging nature Java Moss can also be made into a moss wall. This can be accomplished by folding a net and spreading the moss evenly across it. Then, the net can be secured together by polyester strings, and held on the aquarium wall by using suction cups. It is a slow starter until it has established itself.

It is especially popular among aquarists raising fry (baby fish) and tadpoles, to protect them from cannibalistic adults. Java Moss can also provide food for the newly formed fry, which can be challenging to feed. Some shrimp like to tear the miniature leaves off it to eat.

Java Moss can be easily propagated via division. It is suitable for both aquariums and vivariums

Does Java Moss die if it gets too much light?  Mine never does well, I think maybe too much light?

The thing that kills mine is water that is too warm.  In the racks, my bottom shelves always grow the best moss - cooler down there.

That doesn't bode well for the Java moss I just put in the Discus tank for the Endlers there.  Oh well...

I have had it thrive in low light and up to 83 degrees

I just got my first java moss. I was wondering if it will attach it's self to my rock? I already have the rock in the tank and it's a bigger rock that I really don't want to take out of the tank. I got the moss held onto the rock with other smaller rocks for now.
