What is Amazon Sword Plant?
The Amazon Sword (Echinodorus grisebachii or Echinodorus amazonicus) is native to the Amazon River Basin of South America. It naturally grows along riverbanks and in flooded forest areas, where it lives either fully submerged or partially emersed.
Because of its hardy and adaptable nature, the Amazon Sword plant has become a staple in freshwater aquariums across the world. In the wild, it thrives in soft, warm, nutrient-rich waters with slow-moving currents, conditions that are easy to replicate in home aquariums.
Knowing the aquatic plant's origin helps aquarists better understand what conditions will make this sword thrive in captivity.
Benefits of Having Amazon Sword Plants
1. Biological Filtration
Like all aquatic plants, Amazon Swords help maintain clean water by absorbing harmful compounds like nitrate, ammonia, and nitrite, which are byproducts of fish waste and uneaten food. This reduces the burden on your filtration system and promotes overall tank health.
2. Oxygenation and Water Quality
Healthy, fast-growing Amazon Sword plants contribute to oxygen levels during the day through photosynthesis, benefiting fish, shrimp, and beneficial bacteria.
3. Natural Shelter and Breeding Grounds
The plant’s large, broad leaves offer excellent hiding spots for shy fish, baby fry, and dwarf shrimp. Fish feel more secure in planted tanks, which can lead to reduced stress, better color, and improved behavior.
4. Algae Control
Because Amazon Swords are heavy root feeders, they compete directly with algae for nutrients. A well-fed sword plant can help reduce nuisance algae, especially when combined with proper tank maintenance and lighting control.
5. Visual Appeal and Aquascaping
Their lush, sword-like foliage creates a dramatic backdrop and gives your aquascape a natural, jungle-like feel. These aquarium plants grow tall and broad, making them ideal for background or mid-ground placement in most aquariums.
Create the Ideal Habitat for Amazon Sword Plants
Lighting
Amazon Sword plants do best with moderate to high lighting. Insufficient lighting results in yellow, thin, or melting leaves. Aim for 10–12 hours of light per day using full-spectrum bulbs.
- Ideal light intensity: 2–3 watts per gallon (or 30–50 PAR at substrate level)
-
Recommended lights: High-output LED lights or T5 fluorescent bulbs
In low-light tanks, the plant may survive but will likely grow very slowly and be more prone to nutrient deficiencies.
Substrate
The substrate is critical for successful Amazon Sword growth. These are root-feeding plants, meaning they absorb most of their nutrients through their roots rather than the water column.
- Use nutrient-rich substrates like 2Hr Aquarist Aqua Soil, Oase Scaperline Soil, or UNS Controsoil.
- If using sand or gravel, insert root tabs near the root zone every 4–6 weeks.
Depth matters too; aim for a substrate depth of at least 2.5 to 3 inches to accommodate the plant’s long root structure.
Water Parameters
Amazon Sword plant care involves maintaining stable and favorable water conditions. Fortunately, these plants are adaptable and tolerate a wide range, but they will perform best in the following:
- Temperature: 72°F to 82°F (22–28°C)
- pH: 6.5 to 7.5
- Water hardness: 3–10 dGH (soft to moderately hard water)
Sudden changes in pH or temperature can cause melting or stunted growth, so it’s important to acclimate the plant slowly when introducing it to a new tank.
CO2 Supplementation
CO₂ injection is not mandatory, but it greatly improves growth. In high-tech planted tanks, Amazon Swords develop larger, broader, and more vivid green leaves. In low-tech setups, these plants still do well but will grow at a slower pace. For optimal results:
- Maintain 15–30 ppm CO₂ in planted tanks
- Ensure consistent flow and distribution
Pairing CO₂ with strong lighting and fertilization can take your Amazon Sword from average to extraordinary.
Fertilizer
Because they are heavy feeders, Amazon Swords require consistent fertilization. Neglecting this will result in slow growth, yellowing leaves, and leaf transparency.
Root Fertilization:
- Root tabs are essential, placed directly under or around the plant base
- Replace every 1–2 months
Water Column Fertilization:
- Use liquid fertilizers that supply iron, potassium, and trace elements
- Dose according to manufacturer instructions or based on plant response
A visible iron deficiency will show as pale leaves with green veins, a common issue in iron-poor tanks.
Amazon Sword Plant Propagation
Amazon Swords reproduce through adventitious runners. These long horizontal stems sprout plantlets, each with a small set of leaves and roots.
To propagate:
- Allow plantlets to grow while attached until they form at least 3-4 leaves and visible roots.
- Cut the runner with clean scissors or aquascaping shears.
- Plant the baby sword in the substrate, making sure the crown remains above the surface.
Proper lighting and nutrients will help new plants establish quickly.
How to Plant Amazon Sword in An Aquarium Tank
Planting your Amazon Sword correctly ensures long-term health and prevents rot or melting:
- Rinse the plant before planting to remove any gel or contaminants.
- Use aquascaping tweezers to insert the roots into the substrate gently.
- Bury the roots while keeping the crown (the part where leaves meet the roots) exposed.
- Anchor with stones or plant weights if necessary to prevent uprooting by fish or current.
Don’t plant too close to other species; these plants grow large and need space to expand their broad leaves.
Amazon Sword Plant Tank Mates
The Amazon Sword is peaceful and compatible with most freshwater species. Ideal tank mates include:
- Community fish like Tetras, Rasboras, Guppies, and Mollies
- Dwarf Cichlids such as Apistogramma
- Discus and Angelfish, which enjoy similar water conditions
- Bottom dwellers like Corydoras and Otocinclus
- Freshwater shrimp and Nerite snails
Avoid housing them with these species because they are notorious plant destroyers and will eat or uproot your Amazon Sword:
- Goldfish
- Oscars
- Silver dollars

Amazon Sword Plant Frequently Asked Questions (FAQs)
Do Amazon Sword Plants flower?
Yes, under the right conditions, Amazon Sword plants do flower. While rare in submerged aquariums, they can produce small, white flowers if allowed to grow emersed (partially out of water). In tanks with intense lighting, stable nutrients, and CO₂, it’s possible to see flower stalks even under water.
How to trim Amazon Sword Plants?
To trim an Amazon Sword plant, remove old or damaged leaves at the base near the root crown using sharp scissors. Avoid cutting healthy leaves unless shaping the plant. Regular trimming promotes new growth and prevents overcrowding, especially in smaller tanks.
Do Amazon Sword plants need fertilizer?
Yes, Amazon Sword plants need both root and liquid fertilizers. Being heavy root feeders, they benefit most from nutrient-rich substrates or root tabs. Supplement with liquid fertilizers for iron, potassium, and micronutrients to prevent deficiencies and support overall growth.
