Polypterus Senegalus bichir 5-6cm

Polypterus senegalus, commonly known as the Senegal bichir, is a species of fish belonging to the family Polypteridae. Here is some information about this fascinating fish:

1. Appearance:

   • Senegal bichirs have an elongated, cylindrical body with pectoral and pelvic fins modified into lobed, limb-like structures.
   • They have thick, bony scales known as ganoid scales, which give them a prehistoric appearance.
   • The coloration can vary, but they often have a mottled pattern of brown, green, or gray.

2. Size:

   • Senegal bichirs can grow up to around 14 to 18 inches (35 to 45 cm) in length, depending on factors such as diet, tank conditions, and genetics.

3. Habitat:

   • Native to the freshwaters of West and Central Africa, Senegal bichirs are commonly found in slow-moving rivers, streams, and swamps.
   • They inhabit areas with dense vegetation and submerged branches.

4. Behavior:

   • Senegal bichirs are nocturnal, meaning they are more active during the night.
   • They are often seen lying on the substrate or hiding among plants or other structures during the day.
   • These fish have the ability to breathe air using a modified swim bladder, allowing them to survive in oxygen-deprived water.

5. Diet:

   • Senegal bichirs are carnivorous and primarily feed on smaller fish, invertebrates, and aquatic insects in the wild.
   • In captivity, they can be fed a diet of high-quality pellets, live or frozen foods such as worms, brine shrimp, and small fish.

6. Tank Requirements:

   • A tank size of at least 50 gallons is recommended for a single Senegal bichir, and larger tanks are preferable for multiple individuals.
   • Provide hiding places such as caves, rocks, and driftwood.
   • Maintain a temperature range of 75-82°F (24-28°C) and a pH level around 6.5-7.5.

7. Compatibility:

   • Senegal bichirs are generally peaceful but can be territorial, especially towards their own kind.
   • They can coexist with other large, non-aggressive fish that are not small enough to be considered prey.

8. Breeding:

   • Breeding Senegal bichirs in captivity can be challenging. They are known to lay eggs, and parental care is observed in the wild.

9. Note:

   • Senegal bichirs are sometimes referred to as "dinosaur eels" due to their primitive appearance, but they are not eels. They belong to the ancient group of fish known as bichirs.
