1. Introduction
【Child】: Professor, as I observe these aquatic plants in the aquarium, they remind me of the mystic forests of the elven world in the “Lord of the Rings” trilogy. There is a certain beauty and charm to them. Can you tell me more about such plants?
【Professor】: An enchanting observation, young one! Aquariums filled with vibrant aquatic plants can truly become magical underwater kingdoms, just like the worlds we read about in fantasy novels. Today, allow me to introduce you to one such marvelous aquatic plant, Egeria densa, also known as Brazilian waterweed or Anacharis. We shall unravel its characteristics and how to cultivate it, as well as the precautions to bear in mind. Let’s dive right in, shall we?
2. Characteristics
【Child】: These Egeria densa, they look like the long, flowing hair of the beautiful nymphs from Ovid’s “Metamorphoses.” What else makes them unique?
【Professor】: Your vivid imagination brings life to these plants! Egeria densa indeed has a beguiling appearance. Its slender and flexible stems can grow up to 6.6 feet (2 meters) long, adorned with vibrant green, linear leaves. The leaves grow in whorls of 4 to 8, making the plant’s overall look like underwater feathers dancing in the water.
As for its applications in aquarium layouts, Egeria densa can be used in small to large-size aquariums, bearing in mind that the maximum plant figure achievable will depend on the planting position. It is best positioned in the background, where its lush presence will create a dense, forest-like atmosphere.
3. Cultivation
【Child】: Do they grow at the same pace as the miraculous beanstalk from “Jack and the Beanstalk,” or does it require patience like in “Waiting for Godot?”
【Professor】: What a peculiar juxtaposition! Fear not, Egeria densa’s growth falls somewhere in between those two extremes. It isn’t quite as unrealistic as the beanstalk, but it is known to grow relatively quickly, making it a suitable choice for beginners and experienced individuals alike.
The reason it’s relatively easy to maintain Egeria densa boils down to the plant’s adaptability. It is excellent at acclimatizing to a wide range of lights, CO2 levels, pH, GH, and kH conditions. Furthermore, it thrives between the temperature range of 64.4°F (18°C) and 77°F (25°C) and can flourish in various bottom sands and fertilizers.
Propagation of Egeria densa can happen both underwater and above water. The plant’s cuttings can be placed into the substrate or left to float, and given sufficient light and nutrients, they will quickly grow roots and establish themselves.
4. Precautions
【Child】: If Egeria densa are as enchanting as the Sirens from “The Odyssey,” do they have any drawbacks, or coexistence issues with other organisms?
【Professor】: You are wise to consider the potential for danger amidst beauty! While Egeria densa is mostly seen as a beneficial plant, it can pose certain risks. Due to its fast growth rate, it can quickly blanket an entire aquarium, inhibiting sunlight and oxygen from reaching other aquatic organisms. Hence, it is crucial to keep an eye on its growth and trim it regularly to prevent any harm to other organisms.
In terms of compatibility, Egeria densa can coexist peacefully with most fish species, although special care may be necessary when combining them with plant-eating fish or creatures that could be threatened by the overgrowth of the plant.
5. Summary
【Child】: Thank you, Professor, for unraveling the mysteries of Egeria densa. Our journey has been as insightful as “Alice in Wonderland.”
【Professor】: My pleasure! The captivating world of aquatic plants has endless depths, and Egeria densa is just the beginning. Remember to appreciate its alluring characteristics, while also being mindful of the cultivation requirements and precautions to ensure that your underwater forest continues to enchant all who gaze upon it.
