''Java moss'' is the popular name for Vesicularia dubyana. It is hardy and makes few demands on the water and light. Java moss attaches itself easily to all surfaces, making it suitable for decorating stone and tree roots or hiding aquarium installations. Keep in position with a piece of fishing line until it has attached itself. If growth is too vigorous prune with scissors. Java moss provides a wonderful hiding place for young fish. V. dubyana can also be used in terrariums if the air humidity is high.

New moss can be grown by pulling a few strands from your original clump, and placing the new strands were you want more moss to grow.

This plant grows well with lighting of 1 1/2 watts per gallon. I have also grown this plant in brackish water at 1.004 salinity.
