Anacharis Plant Aquarium: A Versatile Choice for Hobbyists


Aquarium enthusiasts are constantly on the lookout for plants that not only enhance the aesthetic appeal of their tanks but also provide a conducive environment for their aquatic pets. One such plant, the Anacharis plant, has gained popularity due to its adaptability and availability. Anacharis, also known as Brazilian Water Weed, Waterweed, or Elodea, is a versatile plant that can thrive in a wide range of water conditions. This article explores the various aspects of Anacharis care, from buying and planting to its growth rate and propagation.

Buying An Anacharis Plant

If you’re planning to add Anacharis to your aquarium, it’s essential to select healthy specimens that will thrive in your tank. Look for plants with sturdy green stems and vibrant green leaf blades. The leaves should be flat and durable, growing out from the long stem. Be cautious of limp stems, a low number of stems, or plants with leaves that appear dark green or black, or look like they’re dying. Additionally, examine the base of the stems for fine, short white roots and delicate white string-like roots growing outward from other parts of the plant. Healthy Anacharis plants should meet these criteria, ensuring they’ll thrive in your tank.

Anacharis Care: A Beginner’s Delight

Anacharis care is relatively easy, making it an ideal plant for beginners. Its ability to adapt to a wide range of water conditions sets it apart from other aquarium plants. Anacharis can be either planted or left to float, adding versatility to its care routine. Unlike other plants, the challenge lies not in keeping it alive but in controlling its growth so that it doesn’t overtake the tank.

Ideal Water Conditions

Anacharis can thrive in a temperature range of 72 – 78 degrees Fahrenheit and can even survive in cooler temperatures, down to 60 degrees Fahrenheit. It also tolerates a wide range of water parameters, preferring slightly hard water with a pH between 6.5 and 7.5. As for aquarium lighting, moderate levels are ideal, as both low light and intense lighting can result in unwanted algae growth on the plant.

Planting Anacharis: A Step-by-Step Guide

Before you start planting Anacharis, it’s essential to remove the rubber band that usually holds the stems together in stores. The band can cause damage and rot below the substrate, so it’s best to separate the stems and trim off any damaged portions. Plant each stem individually into the gravel or nutrient-rich substrate, ensuring they are about two inches deep and spaced at least an inch apart. Proper spacing allows room for growth and prevents the stems from floating. For a visually pleasing aquascape, consider planting shorter stems in front of longer ones. Over time, Anacharis will develop fine roots throughout the substrate, creating a beautiful forest-like appearance.

The Simplicity of Floating

If you prefer an even easier method, you can choose to float the Anacharis stems in your aquarium. This method allows the plants to grow faster, as they are closer to the light source. Anacharis plants possess efficient nutrient absorption abilities, enabling them to outcompete certain types of algae for essential nutrients.

Anacharis Growth Rate and Trimming

Under ideal conditions, Anacharis can exhibit rapid growth. Factors like intense lighting, longer light hours, and the addition of plant fertilizer or CO2 supplements can greatly accelerate its growth rate. The stems can grow long and develop branches, providing excellent coverage and hiding spots for aquarium shrimp and fish. However, if the growth becomes excessive, gently trim away some of the long stems to maintain balance in your tank. Interestingly, Anacharis plants can even serve as a dietary source for certain fish species, such as Cichlids, Goldfish, and Apple Snails.

Anacharis Propagation and Reproduction

Unlike other aquarium plants, Anacharis does not reproduce through runners or plantlets. It is essentially a long stem without a crown, rhizome, or tubers. Propagation is simple; just cut the stems, ensuring they are around 5 inches long and have an abundance of healthy green leaves. You can then either plant the cut stems or let them float in the water. This straightforward method allows for easy expansion of your Anacharis collection.


Anacharis plants are a versatile and adaptable choice for hobbyists seeking to add a touch of greenery to their aquariums. With its wide range of water condition tolerance and easy-care requirements, Anacharis is a favorite among beginners and experienced aquarists alike. Whether planted or floating, this plant offers a captivating visual appeal while providing a comfortable habitat for aquatic life. So, why not consider incorporating Anacharis into your aquarium and witness the wonders it can create?
