Fontinalis is a genus of aquatic mosses in the family Fontinalaceae. These mosses are commonly known as fountain moss or water moss, and they are found in cool, freshwater habitats such as streams, rivers, and springs.
Fontinalis mosses have a delicate, feathery appearance, with long, slender branches that radiate out from the central stem. The branches are densely covered with tiny, overlapping leaves that help to give the moss its distinctive fountain-like appearance. Fontinalis mosses are important in aquatic ecosystems as they provide cover and habitat for fish and other aquatic animals.
In the aquarium hobby, Fontinalis mosses are highly valued for their attractive appearance and their ease of care. They are often used to create natural-looking aquascapes, and their feathery, delicate structure can add a sense of depth and complexity to the aquarium. Fontinalis mosses prefer cooler water temperatures and moderate to high light intensity. They can be attached to rocks or wood in the aquarium using fishing line or aquarium-safe glue, and they will slowly grow and spread over time. Some popular species of Fontinalis in the aquarium hobby include Fontinalis antipyretica and Fontinalis dalecarlica.
