1. Introduction
【Child】: Professor, I’ve always admired Monet’s Water Lilies paintings. Gazing at them, I often wonder how can I recreate such beauty in my aquarium? What sort of aquatic plants can I use?
【Professor】: Ah, a true masterpiece indeed! Well, I’m glad you asked. One of the most popular aquatic plants that can bring the beauty of Monet’s work to your aquarium is Egeria densa, also known as Anacharis or Brazilian waterweed. In this article, we will discuss its characteristics, cultivation, and precautions.
2. Characteristics
【Child】: Is Egeria densa as elegant as Ophelia floating in Millais’ painting?
【Professor】: What a poetic reference, young one! While not quite as ethereal as Ophelia, Egeria densa is a beautiful plant in its own right. It has slender, delicate stems, with dense, whorled leaves that delicately sway with the flow of water, as if they were performing a ballet for their aquatic audience!
Egeria densa is versatile, allowing various layouts depending on the size of your aquarium. It creates a lush, green underwater forest in larger tanks, or a captivating central piece in smaller ones. It adapts well to its planting position and can achieve a maximum height of around 1 to 1.5 meters.
3. Cultivation
【Child】: In Shakespeare’s words, “to be or not to be… a green-thumbed gardener,” can I grow Egeria densa even without an expert’s touch?
【Professor】: (chuckles) Well-phrased, young bard! Indeed, this plant is suitable for both beginners and experienced aquarium gardeners. It’s quite hardy, and here’s why:
Light amount/CO2: It can thrive in both low and high light conditions. However, to truly flourish, it prefers moderate to high light and CO2 supplementation.
pH, GH, kH: Egeria densa is adaptable to various water conditions. It can tolerate a pH range of 6.5 – 7.5 and moderate hardness levels (GH and kH).
Temperature: Its ideal temperature lies between 15 and 25 °C. Though it can withstand higher temperatures, be cautious, as prolonged exposure may cause it to perish.
Bottom sand/fertilizer: While it can anchor itself in gravel or sand, its primary nutrients come from the water column. Hence, regular liquid fertilization is crucial for its optimal growth.
Propagation: Egeria densa eagerly reproduces by cutting its stem and rooting it or, in times, even by floating fragments above water.
4. Precautions
【Child】: In a place where even the Jabberwock might dwell, should I be wary of Egeria densa wreaking havoc in my underwater wonderland?
【Professor】: Though Egeria densa is generally not a menace, it can grow aggressively under ideal conditions, outcompeting other plants for resources. Regular pruning is essential to prevent overcrowding. Also, some fish, such as goldfish and certain cichlids, may snack on this plant. Be mindful of the plant’s compatibility with your fish species.
5. Summary
【Child】: So, this enchanting Egeria densa shall lead me towards my own artistic masterpiece, floating gracefully like the Lady of Shallot in my watery domain?
【Professor】: Just like Lancelot’s gaze, I am captivated by your analogies, dear child! Indeed, Egeria densa will enhance the beauty of your aquarium, along with being an easy-going and adaptable aquatic plant. With the right care and precautions, Egeria densa shall surely contribute to the charm of your underwater world, filling your heart with the joy of nature and the serenity of the arts!
