Anubias

Anubias is a genus of aquatic and semi-aquatic flowering plants in the family Araceae, native to tropical central and western Africa. They primarily grow in rivers and streams, but can also be found in marshes. They are characterized by broad, thick, dark leaves that come in many different forms. Species can be determined by using mostly characteristics of the inflorescence. Anubias are commonly used in aquariums, usually attached to rocks or bogwood. In contrast to most plants, Anubias generally prefer subdued lighting and can also produce flowers underwater. In the aquarium they should be placed in shaded areas, otherwise algae will develop on the leaves. Anubias are considered by many aquarists some of the easiest plants to maintain, since their light and nutrient requirements are very low and also because herbivorous fish will not eat it. This is why Anubias are some of the few plants which can be used in aquariums with African cichlids and goldfishes.
