Amazon Sword Overview

Amazon Swords are a popular choice for many aquarium enthusiasts. As a member of the Echinodorus genus, they encompass a wide variety of species. These stunning aquatic plants hail from South America, bringing a touch of natural beauty to your tank.

The scientific name for Amazon Swords is Echinodorus amazonicus. They thrive in a variety of water conditions and are relatively easy to care for. In addition to their aesthetic appeal, they also offer benefits like oxygenating the water and providing shelter for fish.

Amazon Swords have large, vibrant green leaves that can grow quite tall. They can become the focal point of your aquarium, giving your underwater landscape depth and structure. Due to their size, they are also excellent options for background plants.

From personal experience, I’ve found that Amazon Swords add a captivating element to any aquarium. Their lush foliage creates a serene and natural environment for my fish. I’ve noticed that my fish particularly enjoy swimming around and exploring the many nooks and crannies that the leaves provide.

Caring for Amazon Swords often involves meeting their lighting and nutrient needs. They typically require moderate lighting and a nutrient-rich substrate to support their growth. Additionally, occasional pruning and trimming can help keep these plants looking their best.

Remember, with a little attention and proper care, Amazon Swords can create a stunning underwater landscape that will delight you and your fish for years to come.

Fundamental Requirements

Caring for Amazon Swords can be straightforward with a little attention to their basic needs. In my experience, these plants thrive in specific conditions that cover tank size, water parameters, lighting, substrate, and temperature.

  • Tank size: The minimum tank size for Amazon Swords is 10 gallons. This gives them ample space to grow and spread without being overcrowded. Remember, healthy Amazon Swords can grow quite large!
  • Water parameters: Maintain a neutral pH of 6.5 to 7.5, with a low to moderate hardness level. Keep the water clean and well-circulated, as stagnant water can lead to deterioration and algae overgrowth.
  • Lighting: Amazon Swords require moderate to high lighting levels. I personally use LED aquarium lights, which I find bring out the vibrant greens in the plant. If you notice the leaves browning or curling, try increasing light exposure.
  • Substrate: A nutrient-rich substrate is a must for robust Amazon Sword growth. I have found that a mixture of fine-grained gravel and specialized aquarium plant substrate helps anchor the roots and provide essential nutrient uptake.
  • Temperature: Amazon Swords are happy in temperatures between 72°F and 82°F (22°C to 28°C). A stable temperature is crucial to maintain the overall health and well-being of the plant.

I recall a time when an Amazon Sword’s leaves became mottled and yellow before I efficiently addressed these factors. By properly catering to these fundamental requirements, my plant recovered and flourished, becoming a striking centerpiece in my aquarium.

Proper Planting Techniques

Amazon Sword plants, or Echinodorus grisebachii, are incredible additions to any aquarium. I’ve found these plants to be a relatively easy and low maintenance option. In this section, we will discuss the proper planting techniques for Amazon Sword plants.

One key to successful planting is to carefully handle the roots. Gently rinse the roots in dechlorinated water before planting. This helps remove any leftover debris, which can negatively impact the plant’s growth.

When choosing a placement, remember that Amazon Sword plants can grow quite large. Ideally, position the plant towards the back or center of your aquarium. This allows the plant to provide a great hiding spot for your fish without dominating the entire space.

For planting, dig a hole in your aquarium’s substrate deep enough to accommodate the roots. Gently insert the Amazon Sword plant into the hole and cover it with the substrate. Be careful not to bury the plant too deep as this can cause the plant to rot.

Keep the following in mind when planting your Amazon Sword:

  • Aquarium lighting: Amazon Sword plants thrive under moderate light conditions. Make sure there is sufficient light, but avoid direct exposure to intense lights that might cause algae growth, which could harm your plant.
  • Substrate type: A nutrient-rich substrate, preferably with a particle size between 1-3 mm, is ideal for Amazon Sword plants. This allows for proper root growth and anchorage.
  • Water quality: Maintain stable water parameters, including pH level (6.0-7.5), water temperature (72-82°F), and a steady supply of essential nutrients, such as iron and potassium.
  • Aquascaping: Amazon Sword plants work well with other aquatic plants and rocks as part of a stunning underwater garden. Make sure not to overcrowd the aquarium, allowing the plants to grow freely.

I remember when I first planted an Amazon Sword plant in my aquarium. It took off so fast that it had quickly become the centerpiece of my tank. Don’t be surprised if your Amazon Sword plant grows bigger and more captivating than you initially imagined!

Nutrient and Supplement Usage

Iron is essential for Amazon Sword growth as it promotes vibrant leaf colors and overall health. I’ve noticed a significant improvement in my plants when adding iron supplements to the water column.

Nutrients are crucial too, and fertilizers containing macro and micronutrients can enhance these plants’ growth. A good mix should include potassium, nitrogen, and phosphorus, among others.

Using root tabs is a great way to provide essential nutrients directly to the plant roots. Every few months, I place root tabs near the base, and the Amazon Sword thrives.

CO2 supplementation can encourage Amazon Sword’s growth, but it’s not necessary. If you choose to add CO2, monitor your aquarium conditions closely to avoid issues with pH imbalances.

Potassium plays a vital role in keeping Amazon Swords healthy. It helps in the proper functioning of enzymes, and lack of potassium may cause yellow leaves. A potassium-enriched fertilizer can make a difference.

Choose your fertilizers wisely, as they may contain beneficial nutrients like iron, potassium, and other essential elements. Always opt for reliable brands, and dose according to the label instructions.

Following these guidelines, your Amazon Sword can grow and flourish, providing a lively and eye-catching addition to your aquarium.

Growth and Maintenance

Amazon Sword plants are popular for their size and growth pattern. They can reach up to 20-24 inches in height. I once had an Amazon Sword that outgrew its tank!

Their growth rate is moderate, meaning they won’t take over your tank overnight. To encourage healthy growth, provide them with a nutrient-rich substrate and adequate lighting.

Runners are a natural part of Amazon Sword’s growth. They will sprout from the base and spread horizontally, eventually forming baby plants.

To maintain a neat and organized appearance, trimming is essential. When the runners grow too long or the leaves become unhealthy, use sharp scissors to trim. This not only keeps the plant in check but also promotes healthy growth.

Maintenance of Amazon Swords is fairly simple. Regularly remove any dead or decaying leaves, and monitor the water parameters, ensuring stability.

In my experience, consistent care and attention to their needs have always resulted in lush, vibrant Amazon Swords. With proper care, your plant will be a centerpiece for your aquarium, providing a beautiful and natural habitat for your aquatic friends.


When it comes to propagating Amazon Sword plants, it’s quite simple. Propagation mostly occurs through the growth of new plantlets from the mother plant.

I remember when I first saw new leaves sprouting from my Amazon Sword. I noticed that the plant was investing its energy into producing a long, thin stem that eventually developed small plantlets along its length. This is known as a runner, which is common in Amazon Sword propagation.

When you see this happening, it’s a sign that your plant is healthy and ready to propagate. Be patient; let the plantlets grow until they have a few leaves and a root system. At this point, you can safely separate them from the mother plant without harming either party.

To separate the plantlets, simply snip the runner connecting them to the mother plant, and plant them into the substrate in your aquarium. Give these new plants space, as they will grow quickly and require ample room to expand.

Keep in mind that propagating Amazon Swords requires adequate conditions, such as proper lighting and a nutrient-rich substrate. By ensuring your plants get the appropriate care, you’ll soon have a thriving underwater garden of lush Amazon Swords.

Water Parameters and Conditions

Amazon Swords thrive in specific water conditions. Let’s discuss the ideal parameters to maintain a healthy plant.

The ideal pH level for Amazon Swords is between 6.0 and 7.5. I once had a tank with a pH of 6.2, and my Amazon Swords flourished! It’s crucial to regularly test your pH levels to keep your plants in good shape.

Water hardness plays a significant role too. Aim for a 3 to 12 dGH range. Soft to moderately hard water helps the Amazon Swords absorb essential nutrients. Remember, wrong water hardness levels can hinder your plant’s growth.

Now, let’s talk temperature. Amazon Swords prefer a temperature range of 22 to 27°C (72 to 82°F). This provides a comfortable environment for plant growth and sustenance. I always make sure to keep a thermometer in my aquarium to monitor water temperature accurately.

In summary, maintain a pH of 6.0 to 7.5, water hardness between 3 to 12 dGH, and a temperature range of 22 to 27°C for healthy and vibrant Amazon Swords. Regular monitoring and adjusting these conditions will keep your aquarium plants, and their inhabitants, happy and thriving.

Tank Mates and Compatibility

When it comes to finding Amazon Sword tank mates, there are plenty of options. Fish such as tetras, plecos, and otocinclus catfish make excellent companions for this aquatic plant.

I once had a tank where I paired Amazon Sword with a beautiful school of tetras. They complemented each other perfectly, creating a vibrant underwater environment. Tetras are small, peaceful fish, making them ideal for coexisting with the Amazon Sword.

Plecos are another great choice as they are gentle and consume algae. This makes them beneficial for maintaining a clean tank while not damaging the plants. However, be aware of the Pleco species you choose, as some may grow too large for your tank.

Similarly, otocinclus catfish are small and efficient algae eaters. They are also peaceful, which helps maintain a serene aquatic environment for your Amazon Swords.

It’s important to note that some fish, like goldfish and oscars, are not ideal tank mates with Amazon Swords. They are notorious for uprooting plants and feasting on their leaves, causing significant damage to the Amazon Sword over time.

In conclusion, Amazon Swords can coexist harmoniously in a tank with small, peaceful, and non-plant-destructive companions. Keep your tank environment clean and balanced by introducing algae eaters such as plecos or otocinclus catfish, and ensure your fish are not prone to destroying your beautiful Amazon Sword.

Dealing with Algae and Health Issues

Algae can be a common issue when keeping Amazon Sword plants in your aquarium. In my experience, I’ve encountered algae growth on the leaves and roots of my Amazon Swords.

To prevent algae growth, ensure your tank has proper lighting, and control nutrient levels. Regular maintenance, like water changes, also helps in preventing algae blooms.

If you already have algae on your Amazon Sword, consider introducing algae-eating species into your aquarium. For example, Plecos and Otocinclus catfish are great options.

Plecos are well-known algae eaters and can help with excessive algae growth on Amazon Sword leaves. However, keep in mind that some larger Pleco species may uproot your plants.

On the other hand, Otocinclus catfish are smaller and more gentle with plants, making them ideal companions for Amazon Swords. They’ll help clean the leaves without causing any harm to the plant.

Remember, combating algae and maintaining your plant’s health requires regular care and attention. With the right balance and maintenance, your Amazon Sword will thrive and add beauty to your aquarium.

Aquascaping with Amazon Sword

Amazon Sword is a fantastic choice for both beginner and experienced aquarists looking to enhance their aquarium’s appearance. As background plants, they create a stunning visual impact and can be a perfect centerpiece due to their large size and vibrant green leaves.

When I first started aquascaping, I was surprised at how easy it was to grow and maintain Amazon Sword. Aqua soil works wonderfully for planting this species, providing essential nutrients for optimal growth.

Remember to keep an eye on their size. Amazon Sword can quickly outgrow smaller aquariums, so be prepared to trim and prune regularly.

Another tip to make your Amazon Sword thrive is to ensure a balance between the light intensity and the available nutrients in the water. Adequate lighting and CO2 supplementation will result in beautiful, robust plants.

Water temperature and pH levels are crucial for plant health. Amazon Sword prefers a neutral pH of around 6.5-7.5 and temperatures between 72-82°F.

Lastly, pay close attention to other tank inhabitants. While Amazon Sword is generally compatible with most aquatic species, large or aggressive fish might damage the delicate leaves. Choose tank mates carefully to ensure a harmonious environment.

In my experience, a well-planned aquascape using Amazon Sword has significantly improved the aesthetics of my aquarium, making it a rewarding and fulfilling endeavor.
