Amazon Sword: Grow & Care for Amazon Sword
Amazon Sword is produced in Brazil. It is a large grass. The leaf length of Amazon Sword can reach 40 cm and the leaf width is 3 cm. Amazon Sword can grow continuously and fulfill a one-meter fish tank in the end. It is also known as the king of tropical aquatic plants and are a variety of tropical plants. The most easily cultivated aquatic plants.

How to Choose and Prepare a Planting Site

Amazon swords can grow in small 10-gallon gallon tanks. An aquarium of that size provides more than enough space to let the plant spread while still maintaining stable water parameters. However, an aquarium of that size isn't enough to let the plant reach its full potential. It’s not a great size if you plan on having many fish either.
We recommend keeping Amazon swords in an aquarium that holds 20 to 30 gallons instead. Larger freshwater tanks offer more vertical space for leaf growth. Plus, the plant won't overcrowd any tank inhabitants.

How to Grow Amazon Sword

The breeding or propagation of this plant is very simple without any hassles. These plants develop long maternal stem, and the plantlets appear on the stem. After some days, the tiny plantlets will start developing their roots with a couple of leaves.
You can keep the plantlets in a submerged condition that will help the plant grow faster with better development. During the propagation period, try to place the developed plantlets in the soil substrate and secure the plantlets of the tree with small stone chips or rocks. Never cut off an underdeveloped young plant or plantlets. Moreover, if you find the small plantlets appearing yellowish then don’t panic because the young Sword Plants are usually yellow in color. You can use liquid plant nutrition as the foods for the growth of the plant like

How to Care for Amazon Sword

For every aquatic plant, the water temperature should be checked before you keep the plant in your aquarium. Follow some necessary requirements to set a tank of Amazon Sword Plant.
  • Temperature
The optimal water temperature range should be 75°F (23 °C) for the comfort of the Amazon Sword Plant.
  • pH Level
The pH level should be around 6.5-7.5.
  • Hardness
The hardness of the water should be 8-12 dGH.
  • Replacement Procedure
Don't change the entire water from the tank at a time, instead try to replace about 25% of the water once in a week to maintain the quality of the water.

Lighting for Amazon Sword

Amazon sword doesn't need strong lighting though more light will result in faster growth albeit boosting algae growth. The best light bulb for an aquarium planted with Amazon sword should produce at least 2 watts per gallon of full-spectrum light that is between 5000K and 7000K. The plant will also need the light to be on for between 10 and 12 hours per day, this includes the light coming from the sun in case your fish tank is in a well-lit room.
However, your Amazon sword light needs may vary depending on the size of your aquarium. So to determine how many watts you need your bulb to produce, divide the total number of watts from a light source by the gallon size of your fish tank. For instance, a 60-watt bulb would offer 3 watts per gallon in a 20-gallon tank. That said, remember too much light will encourage algae growth, therefore, leave your aquarium bulb on for not more than 12 hours per day. Also, consider using a moderate light source instead of a high light fixture.

Filter for Amazon Sword

It is a known fact that plants are natural filters; however, a mechanical filter will help reduce the load of filtration effort from the plants. Ensure you keep a normal filtration system in the tank so that it can help wash out pollutants out of the tank water.

Substrate for Amazon Sword

This plant grows best in the loosely packed substrate or a good alternative like Aquarium gravel. The chosen substrate should have a depth of 2.5 – 3 inches (6 – 8 cm) at the base of the tank. The reason for this is because the Amazon Sword Plant’s roots will grow to be quite large and extensive, growing deep and wide in the tank. Therefore, having enough substrate depth will help to accommodate this plant and ensure that it stays rooted properly. ADA Amazonia soil, Caribsea Eco-Complete Aquasoil, Seachem Flourite Black Sand, etc. are excellent choices and they are rich in essential nutrients. If you have sand or gravel, it is still possible to keep Amazon Sword Plant. However, you will have to use root tabs to provide the necessary nutrients to the plant.

Trimming & Pruning

Thanks to its slow-paced growth, trimming and pruning is not something you have to worry about with Amazon swords. Other than aesthetic trims to keep the plant looking clean, this isn't an area where you'll be spending a lot of time. You can trim off old growth as the plant ages. Older leaves are closer to the outside of the bush. Just pluck the entire leaf off to make way for new development. It's also a good idea to remove any diseased leaves since Amazon swords can succumb to infection. When this happens, the leaves usually turn black and frayed. Remove the affected leaves to prevent the disease from spreading to the base of the plant. Beyond that, just let the plant grow! The main priority for Amazon swords is space. Use trimming to avoid overcrowding. If the plant has ample room to thrive, you won’t have to perform pruning at all.

Supplements for Amazon Sword

CO2 and fertilizer application: Amazon Sword Plant does not require CO2 for healthy growth. However, adding them will significantly increase the growth rate. Fertilizer application also depends on the tank setup. For example, if your substrate is rich with minerals, it can be enough. In other cases, the plant will not perform too well in tanks without fertilizer application. So, you will have to add some from time to time to maintain a normal growth rate and overall good health. Iron and potassium supplements will help it maintain its appealing green coloration and healthy leaf structure, while the additional pressurized CO2 dosing will ensure it grows fast and wider.

Common Problems With Amazon Sword

Algae Growth On Amazon Sword Leaves

Because the Amazon Sword Plant leaves are slow growing, last a while, and love strong light for long hours, they are susceptible to algae growth. If algae growth becomes an issue, its not advisable to attempt to wipe the algae growth off the leaves because they may crack. Instead, its a good idea to have some Amano Shrimp, Red Cherry Shrimp, Nerite Snails, Mystery Snails or Otocinclus Catfish to help keep algae growth in check.
Excess algae growth can be caused by aquarium water conditions and excessive light. So make sure water conditions are satisfactory by testing often and conducting regular partial water changes. And keep levels of visible organic materials and waste from building up. The issue of excessive lighting can be a challenge because this plant likes strong light for long hours. The lighting requirements for this plant make it all the more important that water conditions are as good as they can be.

Yellow and Cracking Leaves

Its not uncommon for some Amazon Sword leaves to begin to die soon after being added to a tank. If this happens, don’t panic. Just gently trim the dead or dying leaves at the stem from the bottom of the plant. As long as all other conditions are proper, the plant should adjust to its new home and begin to grow new leaves.
An Amazon Sword Plant may have a small, stubby rhizome. Its stems are on the short side and its leaves on the long side. Young leaves grow out from the center of the plant, unfolding from the middle. This makes the older leaves being the ones on the outer layers. Young leaves are usually thin and light green when they first come out, turning thicker and darker green as the leaves mature.
Amazon Sword stems are sturdy but their leaves can be delicate. Leaves can crack or tear easily and they cannot repair themselves. Leaves also can turn yellow. Yellow leaves can be from poor tank conditions. This may also mean the plant needs nutrients, so look for plant fertilizer containing iron.
If leaves turn brown, clear, or become covered with algae, gently trim them off close to the bottom of the stem, trying not to disturb the rest of the plant.

Pygmy Chain Sword – This tropical plant is a rapid spreader because if you propagate one then it will grow more branches in the tank. Bottom-dwelling fish love to stay on the leaves of this tree.
Red Mellon Sword – The color of this plant is light-red, which creates beauty in an aquarium. The water temperature should be medium while placing these plants.
Spade-Leaf Sword Plant – The leaves of this North American aquatic plant are circular and broad in shape. This is also prone to algae-like Amazon Sword, so you need to be careful with the cleanliness while placing this plant in the tank. 

Amazon Sword Tankmates

Amazon sword plant is generally a good choice for a community fish tank especially one with calm fish that won’t damage plant parts.
However, the plant is quite hardy and will handle a reasonable number of aggressive species though not as rough as Oscars, Jack Dempsey, and large cichlids.
Fish that snack on live plants are not the best in tanks planted with Amazon sword especially when planted as a decorative element in your tank.
Add Amazon sword in aquariums with fish that love heavily planted tanks like betta and gouramis. The numerous leaves also provide great cover for small fish trying to avoid bullies and young fry in danger of being consumed.
On top of that, Amazon sword does well with or without other plant companions. However, due to its large size and the possibility of outgrowing its designated space, you should consider putting it with smaller aquarium plants.
