The barred bichir is the common name that is also named Polypterus delhezi, Armored Bichir as well as Dalhousie Bichir by many researchers.
Barred bichir or Polypterus delhezi is a primitive, prolonged fish that can be distinguished from all other fish by the presence of up to 15 dorsal finlets.
Barred bichir or Polypterus Delhezi
The barred bichir or Polypterus delhezi, Armored bichir, Band back Bichir is a prolonged fish that is found in the Congo River, especially in the upper and middle parts. This species is most commonly found in commercial pet stores.
The barred bichir or Polypterus delhezi, otherwise known as Barred Bichir, or Armored Bichir is a species of fish of the species Ectinopteragi or Re-fine fish, which forms the class order fish.
Polypterus delhezi is gray, and yellow or green spots have also been noted. Compared with the direction of the surface, the ventral surface looks lighter.
Barred bichir or Polypterus Delhezi is a unique breed of notable old foraging fish, with different characteristics rather than distinguishing them from their near relatives. “The dorsal fin is very distinctive in its shape, made of a series of separate spines.
Most of them have cartilaginous bodies, like sharks, and the primordial shape of the jaw is much more like a salamander than a fish.
In bony fishes, the swimming bladder is an internal, gas-filling chamber, an organ that probably helps the fish to control their air force and stay in the depth of their desired water.
Swimming bladder in Barred bichir or Polypterus Delhezi also serves as a type of lung. The swim bladder is divided into 2 parts, of which the right-handed portion is large enough.
“It acts as an accessory breathing organ and means fish can survive out of the water for some time, but keep it moist.”
For this reason, polypterus is the only known spinal cord to have lungs, but not bronchi. Another aspect of the forbidden beach, which highlights its primitive lineage and survival features, is its vibe.
Scales vary significantly in size, shape, and continuity, and the shapes of fish trunks can usually be used to identify the species from which fish come.
Its fibers are primitive as well, each covered with “guanine”, a substance similar to the enamel in the tooth. ” Bitches also share the characteristics of the ganoid scale, such as those found in sturgeon, paddlefish, gurus, and boffins.
These are thicker than other types of scale, obtained from the Cosmoid scale, and contain a layer of dentine and guanine that is an inorganic bone salt.
They also attach to the peg-and-socket-like joints, thus the ganoid scales do not overlap with each other. “Each scale is shaped like a rhombus and is non-overlapping with the surrounding ones” Barred bichir or Polypterus Delhezi belongs to the “upper jaw” subclass of the polypterus, meaning that its upper jaw extends farther away from the lower jaw.
“Cleaver-shaped cheeks and maxilla (upper outer jaw bone) bear an unusual resemblance to the early ray-fished fish, suggesting a primitive condition of sharing for bonefish”.
Again, this jaw-shaped repetition of the beach’s eating ability and diet, which includes small animals able to suck in their mouths.
An inferior species, Barred bichir or Polypterus Delhezi relies significantly on their sense of smell rather than their disgusting outlook when it comes to food and prey hunt. In the wild, the barred bichirs will hide during the day, only to rise at night to hunt prey.
“Their diet includes whole meat and more and more that can be sucked in the mouth, including small fish, insects, and worms.” This choice for a meaty diet can be noted both in the wild as well as in aquatic pets, where shrimp, Shrimp, and oyster have been identified as the preferred prey.

The barred bichir was first discovered in the Congo River and is commonly found in the upper and middle parts of the Congo River. Although found only in nature in this small region of Central Africa, this species has been in captivity and has become a common fish for aquariums or aquarists.
