Helanthium tenellum Dwarf Chain Sword Aquarium Plant
Helanthium tenellum, also known as Dwarf Chain Sword or Echinodorus tenellus, is a hardy, fast-spreading aquarium plant that creates a lush grassy look in freshwater planted tanks. Its narrow green leaves and runner-style growth make it a great choice for foreground and midground aquascaping.
This compact sword plant can form a beautiful carpet over time when provided with stable water conditions, good lighting, and a nutrient-rich substrate. Helanthium tenellum is popular with both beginner and experienced aquascapers because it is adaptable, attractive, and easier to grow than many demanding carpeting plants.

Planting & Maintenance Tips
Plant Helanthium tenellum in small groups across the foreground or midground, leaving space between each plant so runners can spread. Over time, it will send out new shoots across the substrate and begin forming a grassy carpet.
For best growth, use a nutrient-rich substrate or add root tabs near the roots. Stronger lighting and CO2 supplementation can help the plant grow faster and stay more compact. Trim taller leaves or runners as needed to maintain a clean, even foreground appearance.
