1. Introduction
Child: Professor, have you ever heard of the legend of the “winged seeds” in the world of aquatic plants?
Professor: Ah, you must be referring to Azolla, also known as Giant Duckweed or Water Fern. Indeed, it is a fascinating aquatic plant. In this article, we shall delve into the captivating world of Azolla, exploring its characteristics, cultivation, precautions, and much more.
2. Characteristics
Child: I can’t help but wonder, the leaves of the Azolla remind me of Monet’s “Water Lilies.” Can you please explain a bit more about the appearance and characteristics of Azolla?
Professor: That is an interesting comparison, dear child! The Azolla plant does indeed have small, overlapping leaves that float on the water surface, forming a dense mat. Their leaves possess two colors – green on top and a reddish-purple hue underneath. The plant also has tiny roots that dangle in the water, and it grows exceptionally fast.
In terms of aquarium layouts, Azolla would work best in mid-sized to large-sized aquariums with open water surfaces, as it can occupy the water surface nicely, creating a stunning visual effect. The plant could also grow well near the edges or corners of the aquarium, effortlessly increasing in size and offering a natural habitat for small aquatic creatures.
3. Cultivation
Child: Now that I’m intrigued by Azolla, I can’t help but worry about my ability to cultivate it. Is it as tragic as Hamlet’s fate, or can I thrive like a blossoming lotus in an ancient Chinese poem?
Professor: Fear not, young one, for Azolla is relatively easy to cultivate! It is suitable for both beginners and experienced aquarists alike. One of the reasons for its relatively simple cultivation is that it can adapt to varying light levels and water conditions. Although it indeed grows well in ideal conditions – proper amount of light, CO₂, balanced pH, GH, and KH – it can still survive even if those conditions are not optimal. However, do take note of the temperature, as it prefers a range of 18-28°C.
As for propagation, Azolla can multiply both underwater and above water. Often, new plants will form on their parent plants, and when they are large enough, they will separate and float away to conquer new territories in your aquarium.
4. Precautions
Child: Like Othello and Desdemona’s doomed love, should I be wary of Azolla’s coexistence with other organisms in my aquarium?
Professor: Well, it’s important to be attentive, as Azolla could potentially overgrow and block out sunlight for other aquatic plants, thereby restricting their growth. In such a case, it is recommended to trim and remove excess plants periodically.
As for fish, small fish species, shrimp, and snails will most likely coexist peacefully with Azolla. However, be cautious with larger fish that feed on plants, as they might devour Azolla, leading to a Shakespearean tragedy of sorts in your aquarium.
5. Summary
Child: Could you encapsulate the essence of Azolla in just a few lines like the closing couplet of a Shakespearean sonnet or the brushstrokes of Hokusai’s “The Great Wave off Kanagawa”?
Professor: Certainly, my dear child. Azolla, the captivating aquatic plant, has small overlapping leaves that form a dense, visually enchanting mat. Its cultivation is relatively simple, and with proper care and precautions, it could become a thriving addition to your aquatic world. In conclusion, dive into the enchanting world of Azolla and let it become an alluring gem in your already delightful aquarium.
