Good day, colleagues! Pearly Ctenopoma is an aquarium fish from the Anabasov (labyrinth) genus.
Homeland habitats Ktenopoma are overgrown grass backwaters in the basin of the Congo River. We have already somehow got acquainted with the relative of the heroine of today’s article and today we are acquainted with her relative.
The pearly Ctenopoma has large eyes, an elongated mouth, and a high, flattened body. The ctenopomes are dark gray, one can even say almost black in color, and small blue-green spots are scattered throughout the body. The maximum length of a fish in captivity is no more than 7 centimeters, and life expectancy under good conditions of detention is up to 6 years.
The main distinctive feature of the female from the male is the paler color of the female’s body. During spawning females get brown color.
At the same males during spawning appear iridescent blue spots on the dorsal, anal, caudal fins and on the body.
Ctenopoma has a calm and peaceful temper, albeit a bit shy. Leads mostly nocturnal. Gidrobiont likes to swim calmly in the interweaving of weeds and thickets of grass.
Keeps mostly in the lower or middle layers of water. Ideal with other aquarium fish, similar in habits and sizes.
For the maintenance of a ctenopoma, an aquarium is needed, the volume of which must be at least 60 liters.
It is preferable to contain 3-5 individuals, of which there will be one male and several females. Be sure to organize in the aquarium a sufficient number of different shelters in the form of heaps of stones, weave curtains and ceramic pots.
Do not forget to leave enough fish for free swimming. In the background, plant a large number of long-stemmed plants (vallisneria, hornomy, elodie, Ludwigia, ambulia, cabomba).
Light in the aquarium is needed muffled. Like other representatives of the labyrinth (gourami, lyalius, macropods, labiosis), the ctenopomes periodically rise to the surface for a breath of fresh air.
In view of this feature, cover the aquarium with a cover glass and a lid, because if the fish swallows cold air, it can catch a cold. The optimal conditions of detention are as follows:
- water temperature: 26-30 degrees;
- hardness: 4-25;
- acidity: 6.5-7.5 pH;
- good filtering;
- regular water changes up to 20% by volume.
If you regularly make in the aquarium peat extract, then this way you can strengthen the immune system of fish. Despite the fact that the mother-of-pearl ctenopoma is not picky about food, she still loves to eat live food, and in particular: Artemia, Cyclops, Coretic and bloodworms. Before feeding dry granulated or flaky feed, they must be soaked beforehand.
Also take into account the tendency of the fish to overeat, so adjust the amount of feed supplied.
Sexual maturity of the ctenopoma pearl becomes 8-12 months of age. In order to propagate a ctenopomu, an aquarist will need a 40-liter spawning aquarium, which must contain shelters for females. In addition, the presence of floating plants such as pistii, Riccia, mollusks is welcomed.
These plants will be used by male as a foundation for building a nest. During this process, the fish cannot be disturbed and the sight glass must be covered. Water parameters for breeding ktenopoma are as follows:
- hardness: 4-10;
- temperature 28-30 degrees;
- active reaction: 6.5-7.5 pH;
- the water level in the bank is no more than 15 centimeters.
Before planting spawners, they must be held separately for a couple of weeks. While the females are in another aquarium, the male builds a spawn in the spawning nest for caviar near the surface of the water. By the end of the mating season, the female carries up to a thousand eggs.
Upon completion of spawning, the female is necessarily deposited from the spawning ground. Care of the future offspring is engaged in the male.
The incubation period of caviar is 24-36 hours. Fry can eat independently on day 5. At this point, the male is also deposited, and the water level should be lowered to 5-10 centimeters.
Also ensure good aeration. Keep in mind that the water level in the aqua should be constant until the fry begin to catch air from the surface.
Starter feed for fry: egg yolk, rotifers and ciliates.
