Senegal Bichir Care Guide
Polypterus senegalus · Freshwater Fish
What Senegal Bichir look like
The Senegal Bichir (Polypterus senegalus) exhibits a distinctive, elongated, and laterally compressed body that can reach a maximum adult size of approximately 20 inches (50 cm). Its morphology is characterized by a cylindrical, tube-like shape, reminiscent of ancient fish, which is complemented by a series of sharply spiked dorsal finlets that run along the length of its back, resembling dragon scales. The pectoral fins are robust and adapted for a unique form of locomotion, allowing the fish to 'walk' along the substrate. The head is broad with a pronounced snout, housing a set of sharp, conical teeth that are well-suited for its carnivorous diet. Notably, the species possesses a lateral line system that aids in detecting vibrations in the water, and an adipose fin is present, which is typical of the Polypteridae family. Sexual dimorphism is subtle, with males generally exhibiting slightly more pronounced fin structures and a more vibrant coloration compared to females. Defensive adaptations include its ability to breathe air through a modified swim bladder, allowing it to thrive in low-oxygen environments.
Behavior & temperament
Senegal Bichirs are predominantly solitary and exhibit a benthic lifestyle, often dwelling near the substrate of their aquatic habitats. They are known to be opportunistic ambush predators, employing a stealthy approach to capture prey. While they do not form schools, they may exhibit territorial behavior, particularly during breeding seasons. Breeding occurs through external fertilization, where females scatter eggs among vegetation or substrate, and males will guard the nesting area. Their temperament can vary; while generally calm, they can display aggression towards smaller tank mates or during territorial disputes. Senegal Bichirs are primarily nocturnal, becoming more active during the evening hours when they hunt for food.
Diet & feeding
In the wild, the Senegal Bichir primarily feeds on small fish, crustaceans, and invertebrates, showcasing its carnivorous nature. In captivity, it requires a diet rich in protein, including high-quality pellets, frozen or live foods such as bloodworms, and shrimp to maintain optimal health.
