Bag-haired catfish: in what conditions should be contained?

Good afternoon, dear readers. In today’s article, I would like to touch on one interesting aquarium inhabitant, whom not everyone decides to have in his aquarium.

In this case, we will consider such a fish as a bag-tailed catfish. The first reason why this fish rarely gives birth is its size (it grows up to 30 centimeters in length), and besides, it is also poisonous.

Although domestic aquarists neglect these aquatic organisms, our foreign colleagues quite often set up these fish in their aquariums. In nature, they live in wetlands, where there is a lack of oxygen in the water.

Over the long years of evolution, the intercavity catfish has adapted to such difficult living conditions, and it has acquired a special auxiliary respiratory organ. They have the appearance of a breathing bag that is somewhat similar to an extra lung.

This aquatic species has one unique feature that is characteristic of acne: it can crawl at night from one reservoir to another in search of food. When all small fish in one reservoir is destroyed, the catfish leaves it and goes in search of a new one.

On the way to a new home, the fish do not hesitate to eat a slime or a careless frog. In addition to serious gluttony, bag-worm catfish have a poisonous spike, which helps the fish to defend itself even from people. If you pierce this spike, then the person will receive such a portion of the poison that for two hours the hand becomes numb.

Moreover, paralysis has an upward trend, therefore, with this fish you need to be extremely careful.

Bag-breeding catfish is a bright representative of the catfish group, growing in natural conditions up to half a meter in length. In an aquarium, its dimensions are slightly more modest – no more than 30 centimeters.

This catfish has two primitive lungs, which are located along the body. When a fish needs to crawl from one reservoir to another, catfish collects water into these bags and within a few hours it can move freely on land without damage to health.

The catfish is native to the South-Eastern part of Asia. But these somas are most common in Pakistan, India, Bangladesh, Sri Lanka and Nepal.

Catfish prefers reservoirs with poor oxygen content and with a weak flow of water. Mostly they live in walled ponds and ditches.

There have been cases of course when these catfish found themselves in salt water and in fairly large rivers, but these are rare cases.

The body of the catfish is elongated and compressed at the sides. The head has 4 pairs of long whiskers.

Anal fin elongated with 60-80 rays. The body color of the fish is light brown, but there are cases when albino forms are found.

Due to the unusual structure of the lungs and abundant mucus secretion, the bag-mating catfish easily leaves the reservoirs in search of food.

In the colloquial slang of the sack-sacking, catfish are also called burning. The poisonous glands are located near the thoracic spines in special sacs.

The poison from these glands is extremely painful, it is similar in severity to the bite of a wasp and can sometimes provoke the development of anaphylactic shock. Considering this feature, be extremely careful while cleaning your aquariums as well as when catching aquatic animals from the aquarium.

Life expectancy is quite high, about 6 – 7 years in aquarium conditions.

But in spite of all these negative qualities possessed by the bag-topping catfish, it is quite difficult to call it an aquarium aggressor. To get a painful injection, you need to literally beg for it. You do not need to be afraid of this fish, as it, like other representatives of catfish, is rather shy and prefers to lead a night or twilight lifestyle.

Therefore, when equipping an aquarium under this hydrobiont, you must provide the necessary number of shelters and shady places where the catfish could wait out the day.

When equipping an aquarium for this fish, avoid sharp objects, since the aquatic animal has delicate skin and is free from scales. Close the aquarium with a lid, as the catfish likes to leave their homes.

Due to the large size of the catfish, a large number of waste products is collected in the aquarium. Therefore, in order for the reservoir to be kept clean, it must have powerful filtration and intensive aeration.

In addition, the aquarist will have to replace the water in the aquarium in the amount of ¼ of the volume with fresh settled water every week.

The key to successful maintenance of bag-tailing catfish in aquarium conditions is proper care and balanced feeding. The guarantee of health for any aquarium fish is the correct feeding regimen and a balanced diet.

That is, you have to feed fish with only one type of food every single day, as beginner aquarists like to do when keeping live beetles or harats, feeding them the same dry food every day. In this case, the catfish should be fed as if you have an astronotus in the aquarium.

Since catfish are nocturnal predators, there should be no smaller neighbors in the tank that can be swallowed. Catfish feeds on any food of animal origin, thank God, it is not picky about feeding.

In addition, it is recommended to add worms to the diet. Given the taste preferences and temper of a hydrobiont, its neighbors should be appropriate: other large catfish and large cichlids. The parameters of the catfish should be as follows:

  • Water hardness: 5 – 20;
  • Temperature: 21 -25 degrees;
  • Active reaction environment: 6 – 8 pH;

Catfish become sexually mature at the age of 6 months. Unfortunately, sexual dimorphism is weakly expressed in fish. Multiply fish in a home aquarium, without access to pituitary injections inept aquarist is not possible.

Therefore, in this case I will just briefly tell you how the spawning process proceeds.

Before spawning, the fish changes its color, which becomes spotted. Separate spawning from 100 liters in volume is suitable for spawning, where the separator net and small-leaved plants fit into the bottom. Stimulation to spawning is an increase in water temperature to 29 degrees, while the hardness of the water should be no more than 10 degrees and the active response of the medium should be neutral (about 7.0 pH).

During breeding, the males do not build separate nests where the female will spawn. Spawning proceeds in portions.

During one spawning, the female can produce up to 500 eggs, which are immediately fertilized by the male.

At the end of the spawning period, the producers need to be removed from the aquarium, and the water in the jar needs to be replaced in portions by fresh. A day after spawning, the larvae will hatch from the eggs, which after four days can already feed and swim around the aquarium.

Starter feed for fry – ciliates, live dust and nauplii of Artemia.
