This genus includes a large number of species native to continental tropical
regions. Most are terrestrial, while some are amphibious or aquatic.
Javan moss is very popular among hobbyists as it attaches itself to all types
of decor, whether artificial or natural (wood, rocks). When introducing it into
an aquarium you can help it to establish itself by wedging it with small rocks or
pieces of wood. It likes soft, acid water, with moderate lighting. It offers an
excellent support for the eggs of certain fish, as well as a shelter for fry. It
can sometimes be invaded by filamentous algae. A close species, Bogor's moss (Glossadelphus
zollingeri), is also on the market.
