Fissidens Nobilis Moss (Fissidens nobilis), is a very rare Southeast Asian aquatic moss that is occasionally available for the freshwater aquarium. This plant is a very fluffy, lush green plant with palm-like stems that will attach to most surfaces and can eventually grow into a large mat of impressive size. Like many similar plants, it provides refuge for shrimp and fish fry and makes for an attractive and useful grazing area for shrimp. It can be easily attached to driftwood and rockwork. It is very slow-growing and requires low to moderate lighting.
