Helanthium Tenellum (Dwarf Chain Sword)

Format: Bare-root Plants Pack: 1 Pack

Price
$7.99

Want a foreground carpet without committing to CO₂ and high light? Dwarf Chain Sword is the forgiving option. Narrow grass-like leaves spread by runner into a soft green lawn, and it asks far less than the demanding carpet plants it replaces.

What You’ll Receive

Sold as small bare-root plant portions in the following pack sizes:

1 Pack: Includes 1 small portion, approximately 2–4 small plants
5 Pack: Includes 5 small portions, each portion approximately 2–4 small plants
10 Pack: Includes 10 small portions, each portion approximately 2–4 small plants

Each portion may vary slightly in size due to natural plant growth and harvesting.

Plant Profile

  • Common name — Dwarf Chain Sword
  • Scientific name — Helanthium tenellum
  • Also known as — Echinodorus tenellus (the older name, still widely used)
  • Origin — The Americas, from the southern United States to Argentina
  • Placement — Foreground
  • Shipped size — Small portions of 2-4 plants, roughly 1-3 in
  • Mature height — 2–4 in
  • Suits — 5 gallons and up
  • Growth rate — Medium

Care

  • Difficulty — Beginner. The easiest true carpet plant we sell
  • Light — Medium. Brighter light keeps it shorter and more compact
  • CO₂ — Recommended, not required! It carpets in a low-tech tank, just more slowly
  • Water — 68–82°F · pH 6.5–7.5
  • Substrate — Required. Root feeder — aquasoil or root tabs make the difference
  • Growth habit — Amphibious. Also grows emersed
  • Propagation — Substrate runners

Grower’s Notes

  • It spreads by substrate runner, not floral stalk. Unlike the larger Echinodorus swords that throw an arching stalk up through the water, Helanthium sends stolons sideways under the sand and pops new plantlets up beside the parent. That is what makes it a carpet plant rather than a specimen.
  • Root tabs are what trigger those runners. In inert gravel it survives but sits still — the single reason a Chain Sword fails to carpet.
  • Plant each portion separately, an inch or two apart, and let the runners close the gaps. Planted as one clump, it stays a clump.
  • Expect a settling-in period. It often does nothing visible for two to three weeks while it builds roots, then runs quickly.
  • Plant the crown at the substrate line, never below it. A buried crown rots.

Notes

  • Photos are for reference; portion size and leaf length vary with lighting and nutrients. Some melting or leaf loss during transition is normal.

Customers praised these aquarium plants for arriving healthy with "lots of nice green healthy looking plants with lots of roots." Most found them easy to maintain and appreciated generous portions. However, some shoppers noted plants were smaller than expected with underdeveloped root systems, making them difficult to plant in substrate.

  • Lots of nice green healthy looking plants with lots of roots. Responding well in my tank.
  • Started growing and shooting out runners a half an inch each day in only gravel substrate.

Helanthium Tenellum spreading after three weeks

Very healthy quality. It sat there for three weeks and then suddenly started growing and shooting out runners a half an inch each day in only gravel substrate newly cycled, no CO2. Very satisfied.

Disappointed with item size and roots.

Ordered 20+ various plants and the dwarf chain sword was by far were the biggest disappointment. While the plants arrived green, they were unusable in any type of course substrate. They are quarter inch tall runners with no established root system and too small to plant. I am going to try floating them for now with liquid fertilizer in hope a root system starts to grow. Just not fun getting a plants you cant add to your aqua scape. These also applied as my free plants in the buy 2 get 1 free deal, so now it feels like I never really got the promotion.

I’m all around satisfied with this purchase. There was a good amount of plants to fill the front area of my 29 gallon aquarium. I will buy from this seller again.

Easy to maintain

One reason I purchased these plants was for their easy maintenance. The arrived alive and I was able to rinse them and put them in the tank right away.

Great plants

Very generous portions which were shipped promptly and packaged securely. The plants arrived in excellent shape.

Doing well

I found these a bit hard to plant as they are small and tended to float up out of the substrate. That said, once anchored they have done very well. Look a bit like an upside down spider plant, with the 'babies' growing up instead of hanging down.

This plant arrived well packaged and healthy, displaying great color and healthy roots. I was actually not expecting as large a portion as I received so was very happy. I will be buying plants from Aquarium Plants Factory when I need them due to great prices and having received great plants.

HELANTHIUM TENELLUM purchase

Arrived in great shape, well packaged. Very nice roots and lovely little plants. This was a great buying experience and will absolutely buy from APF again!

How many plants are included in this bare root plant order? Is it just one plant or are they several plants connected by runners?

Aquarium Plants Factory

Approx. a few small plants

M
Mike

How many of these should be bought to cover a 75gal tank as a carpet?

Aquarium Plants Factory

A lot! 85 gal can fill hundred of this plant. But i recommended start around only 20~40 portion to test to see how they grow, you can always add more later. Once they adapted and rooted, they actually grow out quickly.
