1. Introduction
【Child】 Professor, I came across this beautiful aquatic plant called Rotala Macrandra, also known as Red Leaf Bacopa. It reminds me of a fiery sunset melting into a calm ocean. Can we talk about this wonderful plant today?
【Professor】 Oh, I absolutely adore Rotala Macrandra! Your description of a fiery sunset is spot on, my dear friend. I’d be more than happy to discuss its captivating charm and the art of growing it in an aquarium.
2. Characteristics
【Child】 Can you please tell me more about the appearance and characteristics of this plant? I’m keen to know how its leaves change from green to red like the transition of Ovid’s Metamorphoses.
【Professor】 The Rotala Macrandra is an eye-catching and bold aquatic plant native to Southeast Asia. Its leaves are stunning, with a slender and undulating shape. They start as a delicate green hue at the base, gradually changing to a radiant red shade as they grow towards the tips.
The plant has fast growth habits, reaching heights up to 20 inches (50 cm). It can be a stunning centerpiece in both small and large aquariums, depending on the layout. In smaller aquariums, it can serve as a vivid background plant, while in larger ones, you can plant it as a midground plant, forming mesmerizing “fiery” clusters.
3. Cultivation
【Child】 I’ve heard that this plant can be particularly challenging to grow, much like achieving the perfect balance in Shakespeare’s plays. What would you say makes cultivating Rotala Macrandra so demanding?
【Professor】 Indeed, Rotala Macrandra can be a bit of a drama queen to cultivate. I would say it is more suitable for experienced aquarists due to its specific requirements. However, with the right guidance and patience, it is possible to create a scene as enchanting as a Midsummer Night’s Dream.
This plant requires ample light to achieve that delightful red hue. It needs higher CO2 levels and specific water parameters, such as a pH between 6.0 and 7.0, GH from 1 to 12, and KH from 1 to 6. The water temperature should be maintained around 74-86°F (23-30°C).
When it comes to substrates, you should use nutrient-rich bottom sand. This plant loves fertilization, especially iron, to help it achieve its luxurious red foliage.
Rotala Macrandra can be propagated both underwater and above water. Underwater, you can propagate it through stem cuttings. When grown emerged, the plant may produce flowers, and you can propagate it via seeds.
4. Precautions
【Child】 I imagine that piecing this puzzle is close to deciphering an ancient manuscript. Are there any precautions to take when cultivating Rotala Macrandra, and can it coexist with other organisms in the aquarium?
【Professor】 Great analogy! There are a few precautions to consider, just as there might be stumbling blocks while translating ancient texts.
First, be cautious not to over-crowd it or overshadow it with other aquatic plants. It needs plenty of light to thrive and produce its radiant red foliage.
Also, ensure the planted area has enough flow, as stagnant water can hinder the plant’s growth.
When it comes to coexisting with other organisms, Rotala Macrandra is generally peaceful. It can happily share its aquatic abode with other plants and fish; however, it is best to avoid herbivorous fish, as they may find interest in consuming this stunning plant’s leaves.
