Delhezi Bichir – Polypterus Delhezi

Delhezi Bichir

Common name:  Delhizi Bichir, Armored Bichir, Barred Bichir, Banded Bichir

Scientific name:  Polypterus Delhezi

Average Adult Fish Size: 17 iches / 44 cm

Place of Origin: Upper and Middle Congo River, Africa

Typical Tank setup: A well decorated aquarium with well rooted and over hanging plants is appreciated as Bichirs are mainly nocturnal and do not like bright lighting. The base of plants need to be protected by rockwork though, other wise a large bichir will eventually uproot and destroy them.Offer plenty of caves in the form of rockwork and bog/wood/driftwood along with medium to medium-fine sand or gravel as a substrate.

Recommended Minimum Aquarium Capacity: Juveniles can easily be kept in aquariums as small as a 20 gallon /80 litre, but full grown adults need an aquarium with large base dimensions measuring at least 6 feet x 2 feet / 180 cm x 60 cm , or 180 gallon / 720 litre. Depth is not as important as “floor space”.

Compatibility: All Bichirs are relatively peaceful with other fish that are too large too eat. They will eat others of their own kind given the chance though, so other Bichir tankmates should be close to the same size.

Temperature: 77 – 83 Deg F  /  26 – 28 Deg C

Water chemistry: pH 6.0 – 8.0

Feeding: Bichirs are carnivorous so feed meaty type foods consisting of good quality pellets of the appropriate size, sticks, chunks of frozen foods like brine shrimp, mysis shrimp, beef heart, along with chopped market shrimp, chunks of raw fish, and earthworms.

Sexing: The anal fin of the male is larger and thicker than that of the female.

Breeding: Can be breed in aquarium however breeding is very rare. Males have a large pocket like anal fin. Polypterus ornatipinnis scatter their eggs and leave their young to fend for them self.

Additional Information: Even though they are bottom dwellers, they must be able to surface when they feel like it. This is because they breathe oxygen from the air as well. Always ensure that your Bichir has enough room to go up for a fresh breath of air. Always make sure the aquarium is tightly covered with no open holes or means of escape. Bichirs are messy eaters, so provide good filtration and frequent partial water changes to maintain good water quality.
