This stem plant, whose leaves of brown or wine-red color also shine like lacquered, perfectly complement the design of any aquarium. But here we should immediately point out that the rotal can correspond to the description given here only if it receives enough light with a predominantly blue light spectrum. To the water of such high demands, she usually does not show. Most often it is contained in water with average values ​​(12-18 ° dH). Slightly acidic water with the addition of peat extract, as well as a regular (approximately every 2 weeks) water replacement will also contribute to its well-being. Keep the rotal at a temperature of 24 to 28 ° C. Unlike many other stem plants, it does not rise above the surface of the water, but lies (if not cut off) over the water mirror. Shoots usually reach a length of 50-60 cm.
