Care and Compatibility of Gray bichir - Polypterus senegalus

Introduction

Polypterus senegalus, also known as "Senegal Bichir" or "Cuvier's Bichir," is a species of freshwater fish native to Africa. This fish possesses unique characteristics and a prehistoric appearance, making it a popular choice among aquarium enthusiasts.

Polypterus senegalus is an elongated fish with a body covered in hard scales and a pair of long, spiny dorsal fins. Its coloration ranges from dark to light shades, with a pattern of stripes or spots that give it an eye-catching appearance. These fish are considered living fossils, as they have existed on Earth for millions of years.

Behavior

Polypterus senegalus are slow-moving, predatory fish. They spend most of their time near the bottom of the aquarium, where they search for small prey. They are solitary and territorial fish, so it is recommended to keep them in spacious aquariums with hiding places and areas for exploration.

Sexual Dimorphism

Sexual dimorphism in Polypterus senegalus is minimal and difficult to distinguish. Both males and females have a similar appearance. However, males may develop tubercles on their pectoral fins during the breeding season.

Reproduction

Breeding Polypterus senegalus in captivity is a challenging and uncommon process. They are egg scatterers, where the female releases the eggs and the male fertilizes them externally. To stimulate reproduction, changes in water conditions, such as temperature reduction and partial water changes, are required. Providing a suitable spawning site, such as a cave or flat surface for the eggs to adhere to, is necessary.

Aquarium Conditions

Polypterus senegalus, also known as the dinosaur bichir, is a primitive-looking fish that requires a spacious aquarium with abundant hiding spots and exploration areas. It prefers warm, well-oxygenated water, with efficient filtration to maintain water quality.

Feeding

In the wild, Polypterus senegalus feed on a variety of live prey and small aquatic organisms. In the aquarium, they will accept dry foods such as pellets and flakes, but live or frozen foods should also be offered to meet their nutritional needs. Some options include worms, shrimp, insects, and larvae.

Complexity

Caring for Polypterus senegalus can be moderately challenging. They are hardy fish but prone to jumping, so a secure tank lid must be ensured. They are voracious predators and may eat smaller fish, so suitable tank mates must be selected.
