Green Bichir

Green Senegal Bichir, or Polypterus senegalus, is a species of bichir fish that is native to the freshwater systems of West Africa, including the Senegal, Gambia, and Niger rivers. Here are some key characteristics and features of the Green Senegal Bichir:

The Green Senegal Bichir has an elongated, eel-like body with a cylindrical shape. It typically grows to a length of about 12 to 20 inches (30 to 50 centimeters), although some individuals can reach up to 3 feet (90 centimeters). It has a dark green or olive coloration, which serves as excellent camouflage in its natural habitat. The body is covered in hard, armor-like scales called ganoid scales, giving it a prehistoric appearance.

This species has a single dorsal fin located towards the posterior half of its body, as well as a pair of pectoral and pelvic fins. It also possesses a unique pair of primitive lungs, known as labyrinth organs, which allow it to breathe air from the water’s surface. This adaptation enables the Green Senegal Bichir to survive in low-oxygen environments or even briefly leave the water and move across land using its modified pectoral fins.

In the wild, Green Senegal Bichirs inhabit slow-moving rivers, swamps, and floodplains. To replicate their natural habitat, a well-maintained aquarium with a minimum capacity of 50 gallons (189 liters) is necessary. They appreciate a substrate of soft sand or fine gravel, along with hiding spots such as caves, driftwood, or rock formations. Providing a tight-fitting lid is essential to prevent their potential escape.

Green Senegal Bichir is a captivating and primitive fish species that adds a touch of intrigue to an aquarium. Its unique appearance, remarkable adaptations, and ancient lineage make it a sought-after choice for dedicated aquarists and enthusiasts.

III. Is this fish species peaceful or hostile?

Bichirs are predatory fish, with a moderately aggressive temperament.

IV. Species compatibility

Green Senegal Bichirs are primarily nocturnal, and they are solitary ambush predators. They have a relatively peaceful temperament but can be predatory towards smaller tank mates that can fit into their mouth. It is recommended to keep them in larger aquariums with fish of similar size and temperament to avoid potential aggression or predation.

V. How to feed this species?

Green Senegal Bichirs are carnivorous and primarily feed on small fish, insects, crustaceans, and other small aquatic creatures. In an aquarium, they can be fed a varied diet consisting of live or frozen foods such as bloodworms, brine shrimp, earthworms, and small feeder fish. They may also accept high-quality sinking pellets or carnivorous flakes.
