What kind of fish is Polypterus?

albino polypterus

 

Polypterus is known as an ancient fish, and 17 species are known to exist today.

 

In the past, it was also called takigyo, a fish with many fins, and about 10 fins called shoriki are lined up on its back.

 

This fin is lined up to the position of the caudal fin, and Polypterus is characterized by not having a fin corresponding to the caudal fin.

 

Polypterus can be roughly divided into maxillary systems where the upper jaw is longer than the lower jaw and mandibular systems where the lower jaw is longer than the upper jaw. There are many small breeds in the maxillary system, and many large breeds in the mandibular system.

Polypterus endricellii is a representative species of the mandibular system

Polypterus endoliquery is a large species

 

Polypterus endricelli is a large breed with a body length of about 70 cm . Because the striped pattern peculiar to endricelli has a completely different beauty depending on the individual, some enthusiasts keep multiple fish even though it is a large fish.

Because it is a large fish, a large tank is required for breeding, and maintenance costs tend to be high. However, it is easy to breed because it is a strong fish and will eat well if it is artificial food for carnivorous fish.

 

The price starts from a few thousand yen, and a beautiful one with a clear pattern can cost tens of thousands of yen.

In addition to the ones introduced above, there are many types of Polypterus in circulation, and each has a different charm.

polypterus palmas

Like Senegal and Delhedge, it is one of the most popular polypterus varieties.

 

It is a species that swims actively among polypterus, and sometimes comes up to the middle layer for food. It is characterized by the fact that the color of the body changes when the water quality is slightly alkaline.

polypterus rway

It is a subspecies of Palmas and may be called "Butticofary". It is a small breed with a body length of about 30 to 40 cm, and is characterized by dark brown stripes on the body color based on yellow or brown.

Retropinnis is the smallest variety among polypterus, and the body length is about 20 to 30 cm. It is characterized by a reddish-brown to orange body color with a black band, and is popular for its beautiful body color.

 

It may be difficult to obtain because it is expensive due to its low distribution volume.

Polypterus laplady

Lapradi is a subspecies of Bikir and is the smallest breed in the mandibular system with a body length of about 50 cm. It has a wide variety of colors and is characterized by having a large number of dorsal fins next to Bikir.

Breeding method of Polypterus

Polypterus is a tropical fish that is not difficult to keep if you have the equipment.

Rearing small polypterus

Breeding Polypterus

 

Polypterus grows to a length of about 30 cm even for small breeds, so we recommend a tank of at least 60 cm, and if you have multiple breeds, we recommend a tank of 90 cm or more.

The suitable water temperature is 24 to 28 degrees Celsius, and it is particularly vulnerable to low temperatures, so be sure to warm it with a heater in winter.

There is no problem if the water quality is maintained around neutrality of pH 6.5 to 7.5.

Breeding large polypterus

large polypterus

 

When breeding large polypterus, a tank of 120 cm or more is required. Water temperature and water quality conform to small polypterus. Polypterus often pops out, so make sure the lid is tight.

In addition, they are carnivorous and easily pollute the water, and as they grow larger, the amount of food they feed increases and the water quality tends to deteriorate, so choose a filter with high capacity.

 

When breeding multiple large polypterus, the overflow type is also in sight.

/

food for polypterus

Polypterus are carnivorous, so they tend to prefer live or frozen food to artificial food.

 

However, even if artificial food is formulated for carnivorous fish, they will eat it without problems. Polypterus are bottom-swimming fish, so choose a sinking bait.

 

Juveniles grow faster and become larger adults when live baits such as aphids and killifish are given, so it is common to feed them live bait when they are young and switch to artificial bait as they grow.

/

Swimming with Polypterus

Polypterus are carnivorous, so they will eat fish and shrimp that are smaller than themselves. In addition, catfish species such as cichlids and plecos will be attacked on the contrary, so basically it is better to avoid swimming with other species.

 

However, in some cases, it can be successfully mixed with fish such as arowana that live in different layers and are relatively difficult to interfere with other species.

 

On the other hand, even if there is a size difference between Polypterus, it is easy to succeed in mixed swimming. However, when they are young, they try to eat anything, so if you want to mix them, it is better to limit them to polypterus adult fish.

/

polypterus disease

The most important disease to watch out for when breeding Polypterus is parasitism.

 

There is a parasite peculiar to polypterus called polypti, and when it is parasitized, it swims while rubbing its body here and there .

 

As a treatment method, use Green F Gold or Refish to take a bath, but since ancient fish generally have low drug resistance, please treat with 1/3 to 1/2 of the prescribed amount.

The fascinating ancient fish Polypterus!
