Echinodorus Impai – Red Sword Aquarium Plant
Echinodorus Impai is a striking freshwater aquarium sword plant known for its intense crimson to deep ruby-red foliage. This colorful hybrid sword plant adds bold contrast against green aquarium plants and makes a beautiful focal point in planted freshwater aquariums.
Compared to larger sword plant varieties, Echinodorus Impai maintains a more compact rosette growth habit, making it ideal for midground placement or centerpiece displays in medium-sized tanks. As a heavy root feeder, this plant grows best with nutrient-rich substrate or regular root tab supplementation to support healthy leaves, strong roots, and vivid coloration.

Tank Placement
Echinodorus Impai works best as a midground plant or centerpiece in freshwater planted aquariums. Its compact rosette growth makes it more manageable than many larger sword plants while still adding strong color and structure to the aquascape.
This plant typically grows around 8–14 inches tall depending on aquarium conditions, lighting, nutrients, and available space. Place it where its red leaves can stand out against green plants, driftwood, stone, or open foreground areas.
Lighting, CO2 & Nutrients
Echinodorus Impai develops its best crimson to ruby-red coloration under moderate to high lighting. Stronger lighting can help intensify red tones and encourage healthier, more compact growth.
CO2 is not required, but optional CO2 can improve growth speed, leaf density, and color intensity. Like most sword plants, Echinodorus Impai is a heavy root feeder and benefits greatly from nutrient-rich substrate or regular root tab supplementation.
Trimming & Maintenance
Remove older, yellowing, damaged, or melting outer leaves near the base of the plant to encourage clean new growth from the center of the rosette. Keeping older leaves trimmed helps maintain a healthy, attractive shape.
When planting, place the roots fully into the substrate while keeping the crown exposed. Avoid burying the crown too deeply, as this can damage the plant. Once established, avoid frequent relocation so the root system can continue developing.
