Amazon Sword Plant Overview

Amazon Sword Plant is a bushy plant with a short stem. It originally emerged from the middle and lower sections of the Amazon River Basin. The word “sword” refers to their sword-like unique shaped leaves, making them different and stunning. Echinodorus plants are located in the USA, Columbia, and Cuba. Generally, markets sell this plant under the name Paniculatus. Most wild Amazon swords thrive in flora and fauna surrounding the Amazon basin. The plant’s length grows close to 14 inches, and if it is a tall plant, it can grow up to 15-16 inches.

The Amazon Sword Appearance

As these plants fall under the “Echinodorus” genus, they inherit similar appearances, making one mistaken for another. This confusion increases when aquarists keep one or more types of these plants in aquariums. 

The Amazon Sword Plant is a bushy plant with long leaves. Their leaves grow and reach the ground, with great thickness at the middle and narrowing down towards the leaf’s top. We can see cultivars with wide or thin leaves, and a few of them have crinkled edges with defined waves which gives an amazing look for aquascaping.

The Amazon Sword Size

The Amazon Sword Plant Care and Tank Set-Up

Optimum Tank Size For The Amazon Sword Plant

This plant can grow up to 24 inches high, it will do best in a tank larger than 20- 30 gallons. This size will ensure enough space for the vertical growth of the plant and not over-crowd the water tank with tank inhabitants either. Water pH should be between 6.5-7.5 and temperature between 72-82 degrees Fahrenheit. The amazon sword accepts soft to moderately hard water in aquariums as their natives thrive in absolute soft water.

Tank Shape For The Amazon Sword Plant

Since the Amazon Sword plant is very tall, it’s preferable to use deep tanks over small, shallow ones. Although the Amazon Sword survives being partially submerged, it’s not a valid reason to plant them in shallow tanks. This way, you’ll cause their runners to get damaged in shallow tanks.


Even though the highly preferred substrates are sand, gravel, and aqua soil, the Amazon Sword plant can grow in any type of substrate. Begin by planting the Amazon Sword in small grain gravel or, ideally, a specialty planting substrate. As long as the substrate is quite loose for easy rooting and 2.5 inches thick, it’s all good for the amazon plants.

Amazon Sword Plant Substrate

Be very careful while planting it in the sand, as it will be very easy for large fish to uproot it if roots are not well developed.

The Amazon Sword will make an excellent background plant or a centerpiece for large tanks as it grows high and wide. Avoid planting it in small tanks (under 20 gallons) or trimming the leaves constantly to create space in the tanks. Shallow tanks will cause problems for your plant’s growth and leave too little swimming space for the fish.

If you plan to grow your plant similar to its wild natives, consider keeping the water level above the leaf blades for its optimal growth. In the wild, these plants are submerged in marshy water till its leaves and thrive in a boggy environment. 

Fertilize the water column after the weekly water changes to keep the plant healthy and bright green. Iron is the most important nutrient, as well as CO2 root tabs. The Amazon Sword will thrive and grow well even without CO2 supplementation, unlike many plants.

Constantly check for and trim torn or damaged leaves, as they won’t recover. This way, the plant may redirect its energy to healthy extremities and help the tank appear clean and tidy.

Algae are a common problem for this plant, as it lives in warm, tropical water.

Whenever you notice algae growth on the leaves, gently wipe them down to allow the plant to receive all the light and nutrients it can absorb.

Provide 10-12 hours of moderate light per day, at around 3 watts per gallon; you can use a specialty plant bulb or fluorescent tube, as well as a high-quality LED. Strong lighting will also encourage algae growth, so be careful not to provide too much. Always use a moderate amount of light, as excess light invites algae growth or even causes “burns” on the leaves.


The Amazon Sword multiplies by growing a single stem with adventitious runners about 3-4 inches away from one another. These runners will grow into smaller plants, developing their roots, respectively. When fully developed with strong roots, the plant can be cut apart from the mother stem and replanted in the substrate.

Before replanting, you should trim the roots by the ends to encourage faster growth. This plant grows with strong roots; hence make sure you provide thick enough substrate to support their growth.

The Amazon Sword can be compatible with only the plants from the same genus (Echinodorus) and a few species of the Alismataceae family. The spade-leaf sword plant (Echinodorus cordifolius) is one of the most preferred plants. It can grow naturally well in a communal tropical freshwater tank. You can keep various predatory fish species such as tetras or other cichlids in your aquarium. Also, characids and other popular species such as gourami, zebra zebrafish, guppies, mollies, pieds, discus, and angelfish can be great additions to your aquarium. In addition, the bottom dwellers or small cleaners keep the tanks clean, improving the plant’s overall health.

Worst Plants for the Amazon Sword plant Tanks

Avoid large, destructive fish like Plecos, Oscars, Texas Cichlids, or Jack Dempseys, as they can dig up or tear down the stems. Goldfish will constantly try to pull them out and graze on them as on any narrow-leaved plant, so only place these two species together if you want to feed your Goldfish some salad.

Decoration for the Amazon Sword Plant Tanks

Replace your artificial plants with the hardy Amazon Sword to provide your tank with a natural filter and relieve the mechanical one of some extra load. The broad leaves provide some extra privacy to shy fish as well.

Lighting for the Amazon Sword Plant Tanks

The amazon sword plants appreciate moderately bright light. They spread out to their fullest potential when you provide them with 10-12 hours of light. You can either keep them near sunlight ( provided you don’t have fishes as fishes don’t live in warm water) or provide light by using fluorescent or regular filaments. Also, a good aeration system will optimize the growth rate of these plants.
