Tank Placement
Red Rubin Sword works best as a background or centerpiece plant due to its large size and bold coloration. Place it where it has enough room to spread its leaves without shading smaller foreground plants.
This plant is especially effective in medium to large aquariums where its red and bronze tones can stand out against green plants, driftwood, and natural stone.
Lighting, CO2 & Nutrients
Red Rubin Sword does not require CO2 injection, but CO2 can help improve growth rate, leaf size, and coloration. Medium to high lighting helps bring out the richer red and bronze tones.
Like many sword plants, Red Rubin Sword is a heavy root feeder. A nutrient-rich substrate or regular root tabs are strongly recommended, especially when planted in sand or plain gravel.
Trimming & Maintenance
Remove older, damaged, or algae-covered leaves by trimming them near the base of the plant. Regular maintenance helps the plant direct energy toward healthy new growth.
Because Red Rubin Sword can grow large, occasional trimming may be needed to prevent it from shading nearby plants.
Propagation
Red Rubin Sword may produce side shoots or adventitious plantlets over time. Once new plantlets have developed healthy roots, they can be separated and replanted into the substrate.
