The Reedfish, scientifically known as Erpetoichthys calabaricus, is a unique and fascinating species of fish native to the slow-moving waters and swamps of West and Central Africa, particularly found in regions from Nigeria to the Congo. Also commonly referred to as the Ropefish or Snakefish due to its elongated, serpentine body, the Reedfish is a member of the Polypteridae family, which includes the ancient and primitive bichirs.

Characterized by its slim, eel-like body that can reach a notable length, the Reedfish possesses a series of dorsal finlets that run along its back, rather than a single continuous fin. Its skin is smooth, and its coloration typically ranges from olive green to brown, with a lighter underbelly, which allows it to blend seamlessly into its natural environment. The Reedfish is equipped with both lungs and gills, enabling it to breathe air directly from the surface, a necessity in the oxygen-poor waters of its habitat.

In the aquarium, Reedfish are known for their peaceful demeanor and compatibility with a variety of tank mates that are too large to be considered prey. Their unique appearance and behavior make them a popular choice among experienced aquarium enthusiasts. To successfully care for a Reedfish, the aquarium setup should replicate their natural habitat, with plenty of hiding places provided by plants, driftwood, and rocks. A secure lid is essential, as Reedfish are skilled escape artists capable of slithering out of tanks through surprisingly small openings.

Reedfish are nocturnal predators in the wild, feeding on worms, small fish, and crustaceans. In captivity, their diet should include live or frozen foods such as bloodworms, brine shrimp, and earthworms, supplemented with high-quality sinking pellets to ensure proper nutrition. They can occasionally be coaxed into feeding during the day, but they are most active and likely to eat in the evening or at night.

Breeding Reedfish in captivity is a rare occurrence, with few successful reports. The challenge lies in replicating the precise conditions needed for spawning, including changes in water level and temperature that mimic the start of the rainy season in their natural environment. Furthermore, distinguishing between males and females can be difficult, adding another layer of complexity to breeding efforts.

Conservation concerns for the Reedfish include habitat destruction and pollution in their native regions, which threaten their wild populations. While they are not currently listed as endangered, maintaining healthy habitats is crucial for their survival and the overall biodiversity of their ecosystems.

Overall, the Reedfish offers a glimpse into the ancient world of fish evolution, with its primitive features and unique adaptations. For aquarists willing to meet their specific care requirements, Reedfish can be a captivating and rewarding addition to a freshwater aquarium, providing an opportunity to observe one of nature's more unusual and intriguing creations.
