Tank Placement
Rubin Sword works best as a background plant or large centerpiece in freshwater planted aquariums. Its tall leaves and red-bronze coloration create a strong focal point and help fill open areas with lush, structured growth.
This plant typically grows around 12–20 inches tall depending on aquarium conditions, making it best suited for medium to large aquariums. Give it enough space for rosette growth and avoid crowding it too closely with other heavy root-feeding plants.
Lighting, CO2 & Nutrients
Rubin Sword develops its strongest red tones under medium to high lighting. New leaves often emerge with deeper red coloration, while mature leaves may shift toward bronze or green with reddish tones.
CO2 is not required, but optional CO2 can help improve growth, leaf fullness, and overall color. As a heavy root feeder, Rubin Sword benefits greatly from nutrient-rich substrate or regular root tab supplementation to support strong roots, healthy leaves, and long-term growth.
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. Regular maintenance helps keep the plant healthy and attractive.
When planting Rubin Sword, place the roots fully into the substrate while keeping the crown exposed. Avoid burying the crown too deeply, as this can cause rot or plant damage. Once established, avoid frequent relocation so the root system can continue developing.
