Description
This light green lawn-forming Helanthium (Chain sword) is great for aquascaping. It is also sold under the names Echinodorus tenellus, E. tenellus "Green" and Helanthium tenellum "Broad Leaf".
The plantlets are best planted into the substrate individually at a small distance. Under strong light (ideally 0.5 watts/litre or more) and a good nutrient and CO2 supply the plant will readily reproduce by forming long runners with many plantlets. Should it grow too fast, just cut off the new runners. If the lawn has grown too dense you ought to thin it from time to time.
Helanthium tenellum "parvulum" is a light green, usually smaller and wider-leaved form of Helanthium tenellum (= Echinodorus tenellus). It was probably first imported from North America. Decades ago, this was the aquarium plant generally known as Echinodorus tenellus, today it is only rarely cultivated any more. Its submersed leaves are always light green, never reddish, up to a little over 2 mm wide and widest below the middle.
The plant usually sold under the name H. tenellum today was imported from the American tropics (Brazil?), and its submersed leaves are generally of an olive green to reddish colour, longer and narrower (up to around 1.5 mm) that are widest above the middle (see Helanthium tenellum). Its emersed, flowering form also differs clearly from H. tenellum "parvulum".

Healthy and gorgeous plants, extremely fast delivery (even outside Germany!!). Lets say that Aquasabi is simply a must for every aquascaper.
Ein schön großer In Vitro Topf mit vielen einzelnen Pflanzen. Die Pflanzen waren alle in einem sehr guten Zustand. Bin zufrieden.
The plant arrived in very good conditions and started growing immediately at high speed.
I find it beautiful.
Totally worth, I am very happy with it!
