1. Introduction
【Child】: Oh, wise professor! I noticed this fascinating creature that looks like it stepped straight out of an ancient myth. It’s like a sea serpent that escaped a Norse tale. Could you tell me more about this intriguing fish?
【Professor】: Ah, my dear imaginative child, you must be referring to the Polypterus delhezi, commonly known as the armoured bichir. It is an enchanting creature, isn’t it? In this conversation, we shall discuss its characteristics, habitat, husbandry requirements, behavior, breeding, and cautions one needs to be aware of when keeping them in an aquarium.
2. Characteristics
【Child】: This fish almost looks like a dragon, guarding a treasure in a medieval tale. What mysteries lie in its captivating appearance?
【Professor】: Well, young sage, the charm of the Polypterus delhezi lies in its body color, shape, and size. Its elongated, eel-like body can grow up to 14 inches long. The body is adorned in overlapping, scale-like armor, making them appear both prehistoric and mystical. They possess a distinctive dorsal fin composed of multiple separate finlets, giving the illusion of an undulating wave as they swim. Their alluring color ranges from a muted light grey to greenish-blue with darker markings that resemble the cryptic patterns in a sorcerer’s spellbook.
3. Habitat
【Child】: If this fish were a character in a novel, where would its fantastical kingdom be? And how does this kingdom compare to the world it inhabits within an aquarium?
【Professor】: In the grand story of Mother Nature, the Polypterus delhezi dwells in the rivers and swamps of Central Africa. Its watery realm consists of slow-moving, murky waters with an abundance of vegetation and hiding spots. To replicate this magical setting within our aquariums, we must provide a spacious tank with ample hiding spaces, such as driftwood, caves, or plants. Soft, sandy substrate is appreciated by these creatures, as they often skim the bottom searching for food. These enchanting beings play an essential role in their ecosystem, both as predators and sources of food for larger animals.
4. Husbandry Requirements
【Child】: Just like every character has specific needs to flourish in a story, I believe this mystical fish must have its unique requirements. What protocols shall we follow to keep them content?
【Professor】: Indeed, dear child, the Polypterus delhezi has its own set of preferences. Firstly, a water temperature of around 76°F to 82°F is ideal. Water quality must be maintained with a pH of 6.5 to 7.5 and moderate hardness. A minimum tank size of 75 gallons is recommended, as these creatures enjoy their space. Also, be cautious about opening lids, as they are known for their stealthy escapes! Lastly, feeding these legendary beings consists of a varied diet, including sinking pellets, meaty frozen foods such as shrimp and bloodworms, and occasional small fish.
5. Behavior
【Child】: In the tales I have read, creatures often have unique quirks and habits. What fascinating quirks does this magical fish possess?
【Professor】: Ah, the secrets of the Polypterus delhezi’s behavior are as intriguing as any legend! These fish are primarily nocturnal, becoming active and social when the sun sets, much like mythical goblins or fairies. Surprisingly, they are rather peaceful creatures, despite their ferocious appearance. Often, you may see them swimming gracefully near the bottom of the tank, skimming the substrate for tasty morsels.
6. Breeding
【Child】: As romance stories have the lovers’ union, can you tell me how these mystical creatures produce their offspring?
【Professor】: Of course, young bard! The love story of Polypterus delhezi begins with increased water temperature and specific water conditions. The mating dance involves twists, turns, and chases, culminating with the male wrapping himself around the female to fertilize the eggs. The female then scatters the fertilized eggs amongst the plants or on the substrate, and after about 4 to 5 days, the newborn pups emerge!
7. Cautions
【Child】: Just like how mythical creatures can have untamed powers that must be controlled, what concerns should we be aware of when keeping this enchanting fish with others?
【Professor】: Wise observation, dear child! Although the Polypterus delhezi are generally peaceful, they regard smaller tankmates as potential snacks. So it’s best to keep them with other fish of similar size and temperament. Also, provide ample hiding places to minimize territorial disputes.
8. Conclusion
【Child】: Thank you, professor, for transporting me to the mystical realm of Polypterus delhezi!
【Professor】: My pleasure, young one! Remember to appreciate their unique characteristics, attend to their specific requirements, understand their captivating behaviors, and exercise caution to provide them with a wondrous and fulfilling life within your aquarium.
