Description:
|
Compatibility: Aggressive
Maximum Size: 18 inches
Minimum Tank Size: 55G+
Temperature:
Diet: Carnivorous
Level of care: Difficult
General Notes:
The Polypterus Delhezi, from Central Africa and Congo, is also known as an Armoured or Delhezi Birchir.
As with other members of the Polypteidadae family, the bircher is a primitive fish that is recognized by its long and slender body and large pectoral fins.
It requires an aquarium of at least 55 gallons when juvenile. Once full grown, this predatory species may require an even larger aquarium.
The bircher has an accessory organ that helps to draw air out of the atmosphere, so leaving a space betweeen the top of the aquarium and the water line can be beneficial. In the wild, this allows the fish to actually exit the body of water and cross mud flats and small sections of land in search of food and different areas.
These fish are capable of eating any fish that will fit in its mouth and will not hesitate to do so as a result of their predatory nature.
This species is not tolerant of its own kind and is prone to attack other birchirs. It may be kept with larger fish such as cichlids.
[span style="font-style:italic"]This fish is a powerful jumper and escape artist so a good, tight fitting cover is a must.[/span] They prefer a sand substrate and bogwood with assorted plants.

Unfortunately, I find that quite a bit of information in this profile is inaccurate based on my experience with bichirs.
I would hardly classify Polypterus delhezi as an aggressive fish...though it certainly is predatory. The largest P. delhezi I've ever personally seen was about 16 inches long and that was an exceptionally big one. Regarding the level of care....I cannot think of ANY bichir that I would classify as 'difficult' to keep. They are exceptionally hardy fish and adaptable to a wide range of water conditions as long as the water is kept relatively clean by doing regular water changes.
I've kept many Polypterus delhezi juveniles in aquaria as small as 10 gallons (which I usually use as grow-out tanks for little bichirs)....moving them up to 20 gallon Long aquaria and then eventually to larger quarters as they grow. A 55 gallon tank, while not ideal due to its relative narrowness, would be suitable for even a large Armored Bichir.
I have not found Polypterus delhezi to be any more intolerant of other Polypterids than any other species of bichir. Indeed, I commonly keep P. delhezi with other, similarly-sized bichir without any problems. Personally, I do NOT keep bichirs with aggressive cichlids that might cause them injury or stress.

''As with other members of the Polypteidadae family, the bircher is a primitive fish'' This is true
''that is recognized by its long and slender body and large pectoral fins. This is falsethe body shape has nothing to do with primitive or not its where this fish falls on the evolutionary ladder that makes it a primitive fish.
''The bircher has an accessory organ that helps to draw air out of the atmosphere.True its called a lung
''This species is not tolerant of its own kind and is prone to attack other birchirs not in my erxpirence they seem to cohabitat fairly well providing the sized difference is not to great-Anne
