1. Introduction
【Child】 Professor, have you ever read about the mythical Leviathan? I imagine the Polypterus senegalus longfin must be its miniature marine counterpart.
【Professor】 Ah, I see you’re alluding to the ancient sea monster from Judeo-Christian literature. You’re quite perceptive, my young friend. The Polypterus senegalus longfin, or Senegal Bichir, does have an ancient, almost otherworldly appearance. Today, we shall dive deeper into the captivating world of this unique fish species.
2. Characteristics
【Child】 So, Professor, what distinguishes the Polypterus senegalus longfin from the other species we have encountered so far?
【Professor】 Excellent question! The Senegal Bichir is a fascinating species, characterized by its elongated body, dorsal finlets, and its striking long fins. Their bodies are covered in thick scales, similar to those of prehistoric fish, and their coloration ranges from a subtle grey to a muted brown with darker markings. They can grow up to 20 inches in captivity but typically average about 12 inches.
【Child】 Aesthetically, could we consider them the serpents of the aquarium world?
【Professor】 Serpents? Perhaps. Their elongated, snake-like appearance does evoke that imagery. Their peculiar body shape allows for extraordinary mobility, both in water and on land, as they can “walk” using their pectoral fins.
3. Habitat
【Child】 If I were to venture a guess, would the lair of these aquatic dragons be in the murky depths like those from ancient tales?
【Professor】 Very poetic! In reality, the Senegal Bichir is native to rivers and lakes in Africa, where they inhabit slow-moving, shallow waters with plenty of vegetation. They prefer environments with hiding spots, such as tree roots or rock formations, where they can lay in wait for prey. In an aquarium, replicating these conditions is essential to ensure their well-being.
As for their role in the ecosystem, they are considered ambush predators, feeding mainly on smaller aquatic animals and occasionally venturing onto land for terrestrial prey.
4. Husbandry Requirements
【Child】 How, then, can we provide a fitting abode for these ancient enigmas?
【Professor】 To properly house a Senegal Bichir, one needs a spacious aquarium (at least 75 gallons for an adult) with a secure lid and plenty of hiding spots. Water temperature should be maintained between 75-82°F, with a pH of 6.5-7.5 and a moderate hardness.
Feeding them a diet of meaty foods like earthworms, shrimp, and small fish will keep them well-nourished. Remember, they are carnivores, so a protein-rich diet is crucial.
5. Behavior
【Child】 Do these mystical beings prefer solitude or the company of others like their draconian literature counterparts?
【Professor】 Senegal Bichirs are generally solitary and territorial creatures, though they can coexist with other similarly-sized, non-aggressive fish. They are nocturnal, becoming more active during the night to hunt for food. Despite their predatory nature, they tend to be relatively peaceful when properly fed, even with other Bichirs.
6. Breeding
【Child】 Can these serpentine fish multiply their numbers within the confines of our aquatic havens?
【Professor】 Indeed, breeding the Senegal Bichir can be achieved in captivity, although it is not exceptionally common. To encourage breeding, you’ll need a larger tank (100 gallons or more) with shallow water and increased temperature. The males will engage in courtship with the females and fertilize the eggs, which will later stick to plants or other surfaces in the aquarium.
7. Cautions
【Child】 Professor, surely these enigmatic creatures must have their perils when inhabiting our watery domains?
【Professor】 Indeed, there are a few points of caution when keeping Senegal Bichirs. Firstly, they are escape artists, so having a tight-fitting lid is paramount. Secondly, they will eat smaller fish if given the opportunity, so choose tank mates wisely. And finally, they need hiding spaces and subdued lighting to feel secure in their environment.
8. Conclusion
【Child】 So, Professor, have we now unraveled the mysteries of these aquatic serpents?
【Professor】 In a sense, my young friend. We have explored the Senegal Bichir’s unique characteristics, their environmental needs, and the responsibilities that come with keeping them in captivity. I hope this journey has given you a newfound appreciation for these intriguing living relics that grace our aquariums.
