Featured Aquatic plant of the day: Echinodorus Marble Queen (often called the Radican Marble Queen Sword) is a stunning, hardy aquatic sword plant known for its striking, variegated green and creamy-white foliage. It is a large, easy-to-grow foreground to midground plant perfect for open aquariums, tall paludariums, or Discus tanks.
Quick Facts & Care
Origin: Cultivar of Echinodorus cordifolius (North and Central America).
Growth Pattern: Rosulate with large, heart-shaped leaves. It naturally grows tall and will frequently emerge above the water line, making it highly suitable for open-top tanks.
Care Level: Easy
Lighting: Low to medium
Temperature: 22°C to 28°C (72°F to 82°F)
CO2 & Substrate: CO2 is optional but beneficial. Because they are heavy root feeders, they require a nutrient-dense substrate or root tabs.
Local Availability & Sourcing
In the Philippines, the Marble Queen Sword is fairly accessible and budget-friendly. You can commonly find it sold as single bulbs or potted plants.
Best Practices for Your TankPlanting: Plant directly into the substrate. Ensure the crown (where the leaves meet the roots) is entirely above the substrate to prevent rot.
Submersion vs. Emersion: Fully submerged leaves will show softer, more mottled marbling. Because of its desire to grow out of the water, pruning tall emersed aerial leaves will encourage it to produce shorter underwater foliage.
Stability: Like most Amazon Swords, they dislike drastic parameter changes. Unstable environments may cause the plant to experience "melt" (where old leaves decay).
