Som Clarias: conditions of keeping and breeding in a domestic pond

Marble Clarias first came to our aquarium more than 30 years ago in 1995. The range of this large fish extends from the Nile River basin to the southern extremities of the African continent.

These fish are also found in the waters of Turkey, Lebanon, Israel and Jordan. Such a wide distribution of Klarias is due to its good taste and industrial fish farming.

If we talk about the decorative qualities of the marble klarias, then this is a specific fish that is used, as a rule, in show aquariums with a volume of 1000 liters and a length of more than one and a half meters. If the fish will be kept in Spartan conditions on starvation rations, then you may be able to grow a dwarf form, the body length of which will not exceed 30 centimeters.

Just get ready for the fact that the appearance of a hydrobiont will be very poor. The maximum length of the body of marble clararias in the conditions of nature does not exceed 150 centimeters, in conditions of an aquarium – not more than a meter.

As neighbors for these fish, large cichlids, barbs, pacu, armored and flat-headed catfish are selected. If clararias live in a monoculture, they become extremely aggressive and basically one of the largest and strongest survives.

Puberty marble klarias reaches the age of 3 years. Males have a slimmer and brighter body, unlike females. Spawning of these fish is paired and seasonal.

Within one year they can spawn more than 3 times. If the breeding of clarias is put on a trade, then for this purpose it is necessary to use intensive pituitary stimulation.

After stimulation, spawning begins 12 hours later. The fecundity of one female varies from 10 to 15 thousand eggs.

Spawning occurs in special nests, built in ceramic pots and tubes, or in the thickets of aquarium plants. The guard of the future offspring is occupied by a male who will throw at any intruder.

He can even throw himself into the hands of an aquarist if he climbs into his lair. When the water temperature is from 25 to 33 degrees, the incubation period for eggs is 24 to 36 hours, and after another 5 days the yolk sac will completely resolve in the fry.

Starter feed for marbled kriarias fry is zooplankton, and after a week the young klariasa calmly eats a medium-sized pipe builder. As they grow, they transfer to larger species of live food (fish fry, larvae of large insects and shrimp meat), and some types of non-living food.

In order to eliminate the cannibalistic tendencies, the diet of fry of the Clarias includes special feeds, which consist of 1/5 of food of animal origin and 4/5 of vegetable.

These fish grow very quickly, and with abundant nutritious feeding, the youngsters gain from 4 to 6 centimeters in the first month of life, and by the year of their life the body length will increase sevenfold. These fish have a special nadzhaberny body that allows them to endure prolonged oxygen deprivation, temporary dehydration up to 12 hours and a couple of days can live in liquid sludge.

With a strong current and a calm environment, these fish calmly cool themselves at the bottom of the reservoir under a large draft.

When a hydrobiont senses something edible, phlegmatic fish instantly change and go to the source of food, pushing apart all the fish that are found. The injection of the pectoral fin, on which the venomous fin mucus was located, ends for fatal competitors.

You must take this moment into account if you will climb into the aquarium to the Clarias with your bare hands.

Marble clarias are considered aquarium long-liver. Under natural conditions, these large fish, if not caught, can live up to 25 years. If you notice a slight discomfort in their pets, the water in the aquarium should be salted to a value of 10 ppm.

It has been observed that the fish tolerates dyes and antibiotics in the aquarium rather bravely. If a pet has noticed a violation of mucus secretion, then this is easily eliminated with the help of a sand bath.
