Java moss can be attached to rocks and driftwood as a method for softening the edges between hardscape objects and also enables one to create unique features like aquatic trees and moss carpets. Trimming java moss every few weeks will help promote its lateral growth and improve its overall look. Be careful of moss trimmings and other bunches which aren’t attached as they can easily clog filter intakes and impellers.

     Java moss is also a great feature when keeping shrimp or trying to raise fry, the small fish or shrimp will have a place to hide from predators and cannibalistic parents, as well as an environment for scavenging food that settles inside. Perhaps the most impressive feature of java moss is its ability to absorb ammonia and nitrate from the water column. Adding just a few handfuls of moss to your newly set up tank, can help reduce the overall nitrogen load while performing a fish in cycle.
