Aquatic mosses are exceptionally useful and well regarded in the aquarium hobby. The “Java” mosses include the familiar Java Moss (Taxiphyllum barbieri) and newer forms that are showing up: Christmas Tree Moss, Singapore Moss, Weeping Moss, Erect Moss, Creeping Moss, and others.

True wonderments, mosses will grow floating free or attached to an object (rock, wood, ornament, plastic needlepoint mesh, etc.). The root filaments of the moss anchor themselves to these objects, then grow slowly but steadily. A variety of materials is used to anchor the mosses, everything from fishing line to ladies’ fine hairnets. Trim as desired, and use the clippings to make new arrangements or to remove them from the aquarium. These mosses are ideal for breeding fishes. The fry find sanctu¬ary and food in mosses, and often the first sign of new life in the aquarium is tiny flashes of silver in the “Mommy Moss."
