About the Anacharis

Species Type: Freshwater Plants
Category: Stem

Care Level: Very Easy. Adaptable, will tolerate soft or hard water, low light, very minimal or no additional fertilization. pH 6.0 to 8.0 and GH up to 20 degrees/350ppm.

Origin: Native to south eastern Brazil, Argentina, and Uruguay; introduced to many countries in North America, Africa, Asia, Europe and Australia/New Zealand.

Physical Description

A nice beginner plant in that it is both easy to care for and also easy to help set up a "plant" style cycle tank, allowing for addition of fish. Anacharis is a fast grower, and commonly agreed upon as a very good ammonia sink. It does not require much light or the addition of fertilizers, although having both wouldn't hurt. However, because it is a fast grower you will have to trim it every so often as it can get up to 2 feet in length. Also, one can easily grow a bunch of these plants by trimming the top and planting the trimmed stem in the substrate, and it will continue to grow. Very hardy as well.

This plant prefers cooler temperatures than what is found in the normal community tropical aquarium, and frequently will fall apart within a few weeks if kept at warmer temperatures. A closely-related species, Egeria najas, does very well in normal temperatures (optimum 15-26C/60-79F) but is rarely available.

In its natural habitat, this species occurs in very soft acidic water that is stagnant or slow-moving; but it has also been found naturalized (Japan) in very hard basic water.

The Hydrocharitaceae family, commonly known as Frogbit and sometimes Tape-grasses, to which this plant belongs is quite varied; it contains plants as diverse from each other as the subject species, Vallisneria, Limnobium, Elodea and others. There is no real similarity between many of these genera, other than that they are aquatic and flowering.
