Senegal/Cuvier's Bichir Long Fin

Polypterus senegalus, commonly referred to as the Senegal bichir or Cuvier's bichir, is a fascinating freshwater species native to the rivers and swamps of Africa. This ray-finned fish possesses an ancient, eel-like body that showcases a unique blend of features reminiscent of both lungfish and arowanas. Its robust, armor-like scales provide excellent protection, making it well-adapted to its natural habitats. Senegal bichirs are known for their ability to breathe atmospheric oxygen, allowing them to thrive in low-oxygen environments, which is a rare trait among freshwater fish.

The physical appearance of the Senegal bichir is striking, characterized by elongated dorsal fins and a long, streamlined body that can reach lengths of up to 60 cm in captivity. Its coloration typically includes shades of olive to brown with darker spots, enabling it to blend seamlessly into the murky waters of its native environment. This species also features a pair of well-developed pectoral fins that aid in maneuvering through dense vegetation.

In terms of behavior, Senegal bichirs are generally nocturnal and tend to be shy, preferring to hide among rocks and plants during the day. They are solitary creatures, although they can exhibit territorial behavior, particularly during breeding seasons. Their diet primarily consists of smaller fish, crustaceans, and invertebrates, showcasing their carnivorous feeding habits. In captivity, they can adapt well to a variety of diets, which is one reason for their popularity among aquarists.

Senegal bichirs thrive in freshwater environments, typically preferring slow-moving waters with plenty of cover. They can be found in rivers, lakes, and swamps, where they utilize their breathing capabilities to navigate through low-oxygen areas. This adaptability to a range of habitats, combined with their unique appearance and behavior, makes them a sought-after species for aquarium enthusiasts and wholesalers alike.

When caring for Senegal bichirs, it is essential to maintain optimal water parameters to ensure their health and longevity. Ideal water temperature ranges from 24°C to 28°C, with a pH level between 6.5 and 7.5. While they can tolerate a range of conditions, stability is key to preventing stress. A minimum tank size of 200 liters is recommended to provide ample swimming space and hiding spots.

Feeding Senegal bichirs is straightforward, as they are carnivorous and will accept a variety of foods, including high-quality pellets, live or frozen foods such as worms, shrimp, and small fish. Regular feeding should occur 2-3 times a week to maintain their health. Compatibility with other species can vary; they may coexist with larger, peaceful fish but may prey on smaller tank mates.

Acclimation is crucial when introducing Senegal bichirs to a new aquarium. Gradually acclimatize them to the tank environment by floating the sealed bag in the tank for about 15-20 minutes before releasing them. Quarantine new arrivals for at least two weeks to monitor for signs of disease, ensuring a healthy addition to your collection.

Senegal bichirs are suitable for shipping, provided proper care is taken during transit. Packing density should allow for adequate space to prevent stress and injury. They are sensitive to temperature changes and should be shipped at a stable temperature between 24°C and 28°C. As a non-CITES species, there are no restrictions on export, making them an excellent choice for wholesalers and retailers.
