Vesicularia dubyana - the Java Moss - inhabits the amphibious zone of forest streams in South East Asia. It grow well below as well as above the water as long as the air is humid. V. dubyana attaches to rocks and roots also in natural habitats and it is especially suitable for the Nature Aquarium concept where it relatively easy builds beautiful turfs on roots. The Java Moss is sometimes a slow starter but when it has established it does not require any special attention. It accepts all kind of waters - even weakly brackish - and all kind of light qualities at a wide range of temperature. V. dubyana can, however, be tricky when problems with filamentious algae occur because they infiltrate the moss and are almost impossible to remove mechanically. Also, detritus may build up in the moss turf which looks quite unpleasant but a pipette with a moderate flow will soon clean up the mess.
