ABSTRACT:
Ornamental artificial foliage for placement within an aquarium. The foliage formed of a material which is not harmful to the aquatic life within the aquarium. The ornamental foliage has a rough, granular surface texture over and above that normally required for the aesthetic appearance of the foliage. The rough, granular surface provides an increase in the surface area presented by the unmodified foliage to support increased growth and propagation of organisms which are active in causing biological filtration, thereby providing an effective source of biological filtration within the aquarium.
