Introduction
The Endlicheri bichir, also known as the Senegal bichir or grey bichir, is a fascinating and unique freshwater fish species originating from the rivers and lakes of West Africa. A member of the Polypteridae family, it is one of the most primitive fish species alive today, boasting an ancient lineage that can be traced back to over 300 million years ago.
Physical Characteristics
Endlicheri bichirs are characterized by their elongated, eel-like bodies that can reach up to 3 feet (0.9 meters) in length. Their bodies are covered in heavy, bony scales that provide excellent protection, and they possess two rows of small, sharp teeth that run along both sides of their mouths.
Habitat and Distribution
Endlicheri bichirs are found in a wide range of freshwater habitats, including rivers, lakes, swamps, and floodplains. They prefer areas with sandy or muddy bottoms and plenty of vegetation for shelter. Their distribution covers much of West Africa, from Senegal and Guinea in the west to Chad and Cameroon in the east.
Behavior
Endlicheri bichirs are primarily nocturnal predators, spending their days hiding in burrows or under rocks. At night, they emerge to hunt for prey, which consists mainly of smaller fish, insects, and crustaceans. They are opportunistic feeders and will readily consume whatever they can find.
Reproduction
The breeding behavior of Endlicheri bichirs is complex and involves parental care. Females lay eggs in a nest built by the males, and both parents will guard the eggs and hatchlings. The larvae emerge at a tiny size and grow rapidly, reaching sexual maturity in about 2-3 years.
Diet and Nutrition
In the wild, Endlicheri bichirs are opportunistic feeders, consuming a wide variety of small fish, insects, and crustaceans. Captive bichirs require a diet that mimics their natural prey. Live or frozen food items such as feeder fish, brine shrimp, and bloodworms are ideal.
Tank Requirements
Endlicheri bichirs are active swimmers and require a spacious tank. They prefer long, wide tanks with plenty of surface area for swimming. The tank should be heavily planted with live plants to provide shelter and cover. A secure lid is essential to prevent the bichirs from escaping.
Water Parameters
Endlicheri bichirs prefer water temperatures between 75-82°F (24-28°C). The pH should be between 6.5-8.0, and hardness should be between 5-20 dGH. Regular water changes are important to maintain good water quality.
Health and Lifespan
Endlicheri bichirs are generally hardy fish, but they can be sensitive to changes in water conditions. Poor water quality, overcrowding, and improper nutrition can lead to health issues such as bacterial infections, parasitic infections, and skin problems. With proper care, Endlicheri bichirs can live for over 10 years.

Humorous Stories and Lessons
Story 1: A hobbyist named John decided to buy a baby Endlicheri bichir. He placed it in a 20-gallon tank with several small fish. The next morning, he was shocked to find only the bichir and a few empty shells. Lesson: Never underestimate the voracious appetite of a young bichir.
Story 2: Another hobbyist named Mary kept her Endlicheri bichir in a heavily planted tank. One day, she noticed that the bichir had dug a large hole in the sand. She watched in amazement as the bichir emerged from the hole with a live shrimp in its mouth. Lesson: Bichirs are natural burrowers and will create their own hiding places if necessary.
Story 3: A third hobbyist named Tom had a large Endlicheri bichir that seemed to have a fascination with his cat. The bichir would often swim up to the cat and stare at it with its gleaming eyes. One day, the cat got too close to the tank, and the bichir lunged at it, sending the cat scurrying away in fear. Lesson: Bichirs may be curious about other animals, but they should never be approached without caution.
Conclusion
The Endlicheri bichir is an intriguing and fascinating fish species that offers a glimpse into the prehistoric world. With its ancient lineage, unique appearance, and captivating behavior, the Endlicheri bichir is a worthy addition to any aquarium. By providing proper care and housing, hobbyists can enjoy the company of these amazing creatures for many years to come.
