Echinodorus tenellus, commonly sold under the trade name Pygmy Chain Sword, is a diminutive aquatic plant with thread-like leaves only about 1.5mm wide. Though its current scientific name is Helanthium tenellum, it's still most often labeled by the older name. It spreads sideways by sending out runners, making it a popular choice for creating a lush, grass-like carpet in the foreground of an aquarium. As a perennial, once established it keeps propagating through runners, continually producing new plantlets. Under strong lighting the leaves take on a reddish tinge, while a 'Green' form stays green even under strong light, giving keepers a choice depending on the look they want. Rated as beginner-friendly, it's an approachable species even for those just starting out with aquascaping.

- 多年生植物。通过走茎不断增殖
- 体型
- 高5~10厘米(作为草坪),叶片宽约1.5毫米
- 适宜温度
- 18〜28℃
- 浇水
- 需要富含营养的基质。添加CO2会使其更密集
- 光照强度与照明
- 在中等至强烈光照下形成密集的草坪。在强光下大多数品种呈现红色调。
- CO2与肥料
- CO2添加可促进生长和密度增加。应配备富含营养的基质。
- 水温与水质

- 走茎易于蔓延,如果侵入其他前景草的区域应及时拔除。水草不要随意丢弃,防止逃逸到水族箱外。
关于小珍珠(Helanthium tenellum)
Echinodorus tenellus (Pygmy Chain Sword) is a beginner-friendly foreground aquarium plant with 1.5mm-wide leaves that spread via runners into a 5-10cm carpet.
开始养护小珍珠(Helanthium tenellum)前需要了解的7件事
1Light Changes Leaf Color
Strong lighting tends to bring out a reddish tint in the leaves. A 'Green' form that stays green even under strong light is also available, so you can choose based on the look you want.
2Spreads via Runners
This plant multiplies on its own by sending out runners across the substrate. Leave some space between plants when first planting, since it will naturally fill in the gaps over time.
3Watch for Melting After Planting
Stock that was grown emersed (above water) may lose its old leaves shortly after being planted underwater. Give it time to grow in new, fully aquatic leaves before judging how it's doing.
4Plant Shallow and Spaced Out
The fine roots take hold with just a light press into the substrate. Planting too deep can cause the plant to melt or die back, so keep it shallow and give each plant some room.
5Trim Back Overgrowth
Because it spreads continuously via runners, an untended patch can become so dense that light no longer reaches the lower leaves. Thinning and trimming periodically keeps the carpet healthy and even.
6Choosing Healthy Plants
Pick specimens with no discolored or melting leaves, ideally with a healthy plantlet already forming at the end of a runner. Plants with very few leaves may take longer to establish.
7A Fine, Nutrient Substrate Helps
A nutrient-rich, fine-grained aquarium soil makes it easier for the fine roots and runners to take hold and spread. Coarser substrates can make it harder for the roots to anchor.
小珍珠(Helanthium tenellum)的常见问题
- Q.Is this plant suitable for aquascaping beginners?
- A.Yes, it's generally considered beginner-friendly. It's hardy and spreads naturally via runners, making it approachable even if you've never kept aquatic plants before.
- Q.Why do the leaves turn red?
- A.Strong lighting causes the leaves to take on a reddish tint. A 'Green' form is also available that stays green even under strong light.
- Q.How big does it get?
- A.When grown as a carpet, it typically reaches about 5-10cm in height. The individual leaves are very narrow, only around 1.5mm wide.
- Q.How does it propagate?
- A.It spreads by sending out runners that produce new plantlets, gradually filling in outward. As a perennial, once established it keeps multiplying this way over time.
- Q.Do I need to add CO2?
- A.It's not strictly necessary, but supplementing CO2 tends to encourage more vigorous growth and runner production. It's also hardy enough to get by without added CO2.
