Overview

Scientific names: Polypterus delhezi, p. senegalus, p. endlicheri, p. lapradei, p. ansorgii, p. ornatipinnis

 

Bichirs are native to the northeast African Nile River region and its tributaries; they also have the ability to thrive in semi-brackish environments. This dinosaur looking species has been around for millions of years and has changed very little appearance. Their scientific name 'bichir polypterus' means “many fins” referring to the series of spiny dorsal fins. Outside of their unique prehistoric appearance they have another unique feature, bichirs have lungs, in addition to their gills, allowing them to breathe out of water. These lungs, large pectoral fins and the eel/snake like body allows them to move across land for short distances to catch prey or settle into another body of water. Bichirs have poor eyesight, this and being nocturnal they spend their nights hunting for prey. Like sharks, they have a great sense of smell and little organs called Ampullae of Lorenzini that can pick up the weak electrical fields of other animals helping them hunt for food. They are semi-aggressive and can have some aggressive tendencies grabbing anything that will fit in their mouth.

Habitat size

Keep in an appropriately sized aquarium for the species selected, which can range from 90 gallons for a smaller species, to a much larger aquarium for larger growing species.

 

 

Building your habitat

  • Water health
    • Provide proper filtration to ensure optimal water quality to help maintain health; low to moderate water circulation should be provided to mimic the water currents found in the bichir’s natural habitat
    • Stable water quality (pH, ammonia, nitrate, nitrite) and water temperature are critical to the health of aquatic life; if you are unsure of your water quality, bring a sample to Petco for free testing
    • An aquatic heater should be utilized to stabilize water temperature, ensuring it does not fluctuate more than 2 degrees in either direction in a 24-hour period
    • Bichir’s will benefit from the addition of freshwater salt to the aquarium. The specific gravity should be kept at 1.004; do not allow specific gravity to fluctuate more than 0.001 in either direction in a 24-hour period.

 

  • Décor: Provide plenty of space for swimming, as well as plants, rocks or décor for hiding places
  • A top should be added to the aquarium as they can jump out of the aquarium

 

Feeding
A well-balanced bichir diet consists of:

·       Brine shrimp, mysis shrimp, bloodworms, tubifex, crustaceans (live, freeze-dried, or frozen) and carnivorous pellets.

 

Things to remember when feeding your bichir:

·       Feed small amounts two to three times daily, no more than your fish will eat in 1–2 minutes

·       Thaw frozen food before feeding

·       Nocturnal, food should be provided at night

 

 

Bichir care

  • Maintaining great water quality with regular water changes and adequate filtration is important to help keep your bichir healthy
    • Daily: Check filter, water temperature and other equipment
    • Weekly: Test water quality at least once a week
    • Weekly to monthly: Change 10–25% of the total volume of water every 2–4 weeks, or as needed; change filter media monthly
  • Avoid overcrowded conditions, which are a major cause of stress and disease
