The Amazon Sword is a large and robust plant that can grow up to 20 inches tall. It has long, narrow leaves that can reach up to 10 inches in length. The leaves are a vibrant green color and have a slightly pointed shape, resembling a sword. This plant is native to the Amazon River basin in South America, hence its name.

Commonly referred to as the Sword Plant due to its sword-like appearance. It is a popular choice for aquariums because of its ability to grow quickly and fill up empty spaces in the tank. It is also a great plant for beginners as it is easy to care for and can thrive in a variety of water conditions.


One of the most notable characteristics of the Amazon Sword is its ability to grow both submerged and emersed. When grown in an aquarium, it will produce long, narrow leaves that grow towards the surface of the water. However, if grown in a terrarium or partially submerged, it will produce broader leaves that grow outwards. This versatility makes it a great plant for both aquariums and paludariums.

Another characteristic of the Amazon Sword is its ability to absorb nutrients from the water through its roots. This makes it an excellent plant for keeping the water in your aquarium clean and healthy for your fish. It also helps to prevent algae growth by competing for the same nutrients.


The Amazon Sword is a low-maintenance plant, making it a great choice for beginners. It can thrive in a variety of water conditions, but it does prefer slightly acidic water with a pH of 6.5-7.5. It also requires moderate to high lighting, so be sure to provide enough light for it to grow and thrive.

To plant the Amazon Sword, simply bury the roots in the substrate and make sure the crown of the plant is above the substrate. It is a heavy feeder, so it is recommended to supplement with root tabs or liquid fertilizers to ensure it receives enough nutrients.

Tips for Growing Healthy Amazon Sword

Choosing the Right Substrate

The first step in growing healthy Amazon swords is choosing the right substrate. These plants prefer a nutrient-rich substrate that will provide them with the necessary nutrients to grow. It is important to avoid using plain aquarium gravel, as it does not contain enough nutrients for these plants.

Providing Adequate Lighting

Amazon swords require moderate to high lighting in order to grow properly. This can be achieved through the use of fluorescent or LED lights. It is important to research the specific lighting needs of your particular species of Amazon sword, as some may require more or less light than others.

Supplementing with CO2

In addition to proper lighting, Amazon swords also benefit from the addition of CO2 to the aquarium. This can be achieved through the use of a CO2 injection system or by adding liquid CO2 supplements. CO2 helps these plants to grow faster and healthier, and can also prevent algae growth.

Fertilizing Regularly

Fertilizing is an essential part of caring for Amazon swords. They need a steady supply of nutrients in order to grow and thrive. It is recommended to use a liquid fertilizer specifically designed for aquarium plants, and to follow the instructions on the label for proper dosage and frequency.

Trimming and Pruning

As Amazon swords grow, they may become too large for the aquarium or start to overshadow other plants. It is important to regularly trim and prune these plants to maintain their size and shape. This can be done by cutting off any dead or damaged leaves, as well as trimming back any overgrown areas.

Avoiding Algae Growth

Algae can be a common problem for aquarium plants, including Amazon swords. To prevent algae growth, it is important to maintain proper lighting and nutrient, as well as regularly cleaning the aquarium and removing any decaying plant matter. Additionally, adding algae-eating fish or snails to the tank can help keep algae under control.

Propagating Amazon Swords

One of the benefits of Amazon swords is that they can easily be propagated through division. Simply cut the plant into smaller sections and replant them in the substrate. This not only helps to control the size of the plant, but also allows for the growth of new, healthy plants.

By following these tips for growing healthy Amazon swords, you can enjoy a beautiful and thriving aquarium. Remember to research the specific needs of your particular species of Amazon sword and make adjustments as needed. With proper care, these plants can add a vibrant and natural touch to any aquarium.
