Hello dear readers! Polyperus Senegalese – is a hydrobiont belonging to the family Mnogoperovyh. The habitat of this aquarium fish are freshwater reservoirs of the African continent.
In particular, the fish do not like deep rivers, namely the White Nile, Congo, and the three lakes – Albert, Chad and Turkana. Polyperus prefers to stay away from strong currents.
Basically he swims in the thickets of plants or hides in shelters near the shore.
Senegalese polypherus have an unusual appearance and look like an old reptile than a fish. For this reason, the aquatic animal is dubbed the second name – dragon fish.
The body is snake-like and covered with powerful scales. The main color of the fish is silver-gray with an olive sheen.
On the back there are from 5 to 18 fins that resemble spikes. The ventral fins are located near the anal fin, which is also close to the caudal fin.
The tail and chest oval shape, thanks to which the fish moves well in the water. Unfortunately, sex differences are mild. In females, the head is wide, in males during spawning, the spade fin increases.
In nature, dragonfish can reach 70 centimeters in length, but in aquarium conditions, they rarely exceed 40 centimeters. In aquariums polypteruses live about 10 years.
Polypterus are lungfish that can absorb oxygen from water and from atmospheric air. Without air, the fish will die in a couple of hours.
In addition, the dragon fish may be out of the water for some time, but with one important condition – if its skin is moist. This is especially important when the fish crawls from the pond into the pond.
If you keep this fish in an aquarium, it is very important to give it the opportunity to get to the atmospheric air.
The lack of vision in the fish is compensated by a good sense of smell. Polyparus Senegalese is nocturnal and goes in search of food at dusk.
As neighbors of polyterus, you can add cichlids, large labyrinths, astronotus, barbs Denison and fire barbs, cancer. Since the fish is a predator, all small fish goes as feed, regardless of its belonging to any family. While the fish is in the fry stage, it spends most of the time in the flock, and as it gets older, it begins to isolate itself.
An adult individual needs sufficient free space for swimming and for personal territory. Thus, the aggression will be reduced to a minimum, and this is especially true in aquariums with a small volume.
Lay on the bottom of the aquarium a sufficient number of various shelters in the form of caves, snags, stones.
Based on the size of polypterus, for an adult fish, an aquarium with a volume of 200 liters is required. Since the fish is kept mostly near the bottom, the height of the tank does not play any role.
Without fail, cover the aquarium with a cover with cover glass, as the fish may leave the pond and die. The parameters of aquarium water for the maintenance of hydrobiont are as follows:
- water temperature: 25-30 degrees;
- hardness: 4-18;
- active reaction environment: 6.0-7.5 pH;
- weekly changes and good filtration with aeration.
You can filter the water with any available filter, but the best filtering effect can be achieved by using external filters. To feed your pets you need a live feed.
You can enter into the diet shrimp, squid meat, bloodworm, earthworms, beef heart and meat, small fish. In addition, the Senegalese polyterus well feeds on dry granulated fodder.
Polypterols multiply from July to October. Those individuals who led a solitary life, begin to appear before the eyes with the marriage partner. A sign of the manifestation of attention to individuals of the opposite sex is frequent contact with the bodies and biting of the fins.
After a few days of such courtship, the female sweeps away small-sized eggs, which is immediately attached to the aquarium plants. The ideal substrate for spawning is Javanese moss.
Upon completion of spawning, remove the spawn from the spawn, because it will be eaten by the parents as soon as possible.
The nursery aquarium should be equipped with powerful filtration and aeration. In addition, it is often necessary to replace a small amount of water with a fresh one.
For the whole week of life, the fry feed on yolk sacs. After a while the fry can be fed with nauplii of artemia.
It is extremely difficult to grow young polypterus because after the next feeding you will have to siphon the soil and at the same time make sure that the fry are not sucked into the funnel. As they grow up small things, it is sorted and deposited, as they can eat each other.
As soon as the fish overcome the 5 centimeter length, they are no longer so demanding to the content. At this point, the sorting of the fry by size can be stopped and it can be changed a little less.
In addition, the fry will independently swim to the surface and grab the atmospheric air.
