The Red Flame Sword, scientifically known as Echinodorus ‘Red Flame’, is a striking and easy-to-care-for aquatic plant that adds bold coloration and texture to freshwater aquariums. A cultivated hybrid of the popular Amazon Sword, this species is valued for its vibrant red and green leaves, which create a dramatic focal point in planted tanks.

Physically, the Red Flame Sword features broad, lance-shaped leaves with a bright green base color covered in red or maroon speckles. Newer leaves often display a deeper red hue, which fades slightly as they mature, while older leaves maintain their speckled appearance. The plant can grow up to 12 to 20 inches (30 to 50 centimeters) tall, making it suitable as a midground or background plant in larger aquariums.

In the aquarium, the Red Flame Sword thrives when planted in nutrient-rich substrate, such as aquarium soil or fertilized gravel, which supports its root system. Moderate to high lighting is recommended to encourage its red coloration, as insufficient light may cause the plant to lose its vibrant hues. The addition of CO₂ injection is not strictly necessary but can enhance growth and coloration. Regular dosing with liquid fertilizers that contain iron and other trace elements helps maintain its health and vivid appearance.

Water parameters for the Red Flame Sword should replicate the conditions of its tropical origins. It prefers slightly acidic to neutral water with a pH range of 6.5 to 7.5 and temperatures between 72 to 82°F (22 to 28°C). The plant tolerates a wide range of conditions, making it suitable for beginners and experienced aquarists alike. Regular trimming of older leaves encourages new growth and prevents the plant from overshadowing smaller tankmates or other plants.

The Red Flame Sword is a hardy and adaptable plant that complements a variety of aquascaping styles, from lush jungle layouts to minimalist designs. It pairs well with other aquatic plants such as Anubias, Java Ferns, and Vallisneria, creating a visually dynamic aquarium. Its broad leaves also provide shelter and grazing areas for fish and invertebrates, making it a functional addition to community tanks.

Propagation of the Red Flame Sword is straightforward. The plant reproduces by producing runners or side shoots, which develop small plantlets. These can be separated from the parent plant once they have developed a sufficient root system and replanted in the substrate. Regular maintenance and trimming ensure optimal growth and prevent the plant from becoming too dominant in the aquarium.

Overall, the Red Flame Sword (Echinodorus ‘Red Flame’) is a stunning and versatile plant that brings vibrant color and natural beauty to freshwater aquariums. Its striking appearance, ease of care, and compatibility with various tank setups make it a favorite choice for aquarists of all experience levels.
