Bagmaking catfish (lat. Heteropneustes fossilis) found in the homes of many aquarists.
Its natural habitat is freshwater in South-East Asia, Laos, Vietnam, Thailand, India, Burma, and the island of Sri Lanka. The bag-tapping catfish belongs to the bag-tabernacle family, under natural conditions it can grow to an impressive size – 60-70 centimeters, in the aquarium its dimensions reach 25-35 centimeters.
There are several variations of the color of fish – brown, gray-black and albino. A bag-tailed catfish has a snake-like body, slightly flat on the sides.
When he swims, the body twists like a snake. Head pointed, small size, small eyes. 8 long whiskers are located in pairs near the mouth.
Additional respiratory organs can be seen near the gill flaps and right up to the tail – thanks to them, the catfish can still lie in the mud or breathe air from the surface.

The fins of this inhabitant of the aquarium are small, slightly rounded, but the anal fin is pointed and long. There are poisonous spines on the dorsal and pectoral fin, so you need to be careful when taking the catfish.
Injections of these thorns are very painful, and the effect of the poison resembles a bee, so such a fish is a danger to people who are predisposed to allergies.
Sexual dimorphism is expressed not too explicitly: it can be said that females of the bag-worm catfish are somewhat larger and fuller than the males. These are predatory fish, but they are quite suitable for keeping in a specific aquarium.
You cannot keep a bag-tailed catfish with small fish – they will serve as food for it. Most often, representatives of this species prefer solitary existence, they are active only after dark, and during the day they hide in silt or shelters.
Sometimes, catfish can fight for territory, although they are often peace-loving fish that show aggression only if someone attacks them. At a young age, catfish have a good compatibility with small fish – until they outgrow them, after this telescopes, small guppies, danios, neons, angelfish and other fish are better to plant.
Laboos, cichlids, large species of barbs, polypteruses, gourami, iris, Kalamohty, fish-knives will be good neighbors for catfish. Sometimes sack-sacks are kept with parrot fish.
Often, the bag-sabotage catfish keeps close to the bottom of the aquarium – there it collects food, so you can keep it with up-water fish.
- This species got its name because instead of light they have a pair of cylindrical air bags, it is located from the tail to the gills. When the catfish is on land, the water that has been preserved in the gills does not allow them to dry out, so that the fish can live for several hours without water;
- Representatives of this species often rise to the surface, they swallow air;
- Bag-tailed catfish can live only in flowing and oxygen-saturated water, otherwise the fish will die in 5-7 hours;
- Representatives of this species can be called long-livers, they can live in artificial conditions up to 12 years;
- The size of the bag-tailing catfish depends on the size of the tank in which it is contained, under normal conditions, the fish grows to 35 centimeters, and if the aquarium is small, the growth of its inhabitants slows down.
Bagging Catfish can not be called capricious fish. During the daytime, he most often hides in shelters or lies motionless at the bottom; make sure that there are a sufficient number of stones, snags and caves in your tank. The volume of the aquarium can vary from 100 liters or more.
It is desirable that the fish had enough space for swimming.

Regarding the parameters of water, maintain the temperature at 21-25 degrees, the hardness can reach 20 °, the pH is slightly higher than neutral – 6.5-7.5. The tank should be equipped with a filter and aeration system. You also need to change the water in time: weekly replace about a quarter of the water with fresh.
It is advisable to cover the aquarium with a lid: if the catfish accidentally jumps out, it can survive for a couple of hours without water, but nothing will save it from damage due to a fall from a height.
When choosing a soil, pay attention to small pebbles, a layer with a thickness of 1.5-2 centimeters is enough. Lighting fish loves weak and scattered, in the morning an aquarium can be placed near the window, and then it is slightly tinted.
When catching a bag-haired catfish with a net, you need to be careful. This is a non-aggressive fish, but when attacked, it will defend itself with poisonous thorns.
As for feeding, these inhabitants of the aquarium are quite voracious, therefore they absorb both live food and artificial substitutes. From live food, you can give the soma pieces of shrimp, fish, scraped meat and so on.
Fry begin to feed artemia.
Sexual maturity in the bag-som catfish occurs in 1.5-2 years. During spawning, you can see the characteristic changes in color: from monochromatic it becomes spotty.
In aquariums, independent reproduction is impossible, therefore, aquarists often resort to the method of pituitary injections.
The minimum spawning volume is 100 liters, the spawning grid covered with small-leaved plants fits into the bottom, you also need to put a few shelters. The temperature of the water rises gradually to 27-29 degrees, and it will become an additional stimulation to spawn.
Carbonate hardness should be minimal – up to 10 °, pH 7.0.
Males, unlike other species, do not build caviar nests, females toss it in clusters. At one time, the female sweeps up to 500 pieces of yellowish eggs, which the male fertilizes.
Parents after spawning is better to plant, and then replace a quarter of the water. The incubation period lasts a day, after which the larvae are born.
Whitened unfertilized eggs must be removed in a timely manner. Fry begin to feed and swim in 3-4 days.
Small catfish have a disproportionately large head, they have little resemblance to their parents until they reach 5 centimeters. In the first days of life, the fry do not have additional respiratory organs, therefore the water level in the spawn should not exceed 20 centimeters. Gradually, kids are transferred to larger feed.
Somiki can grow unevenly, so it is advisable to remove large individuals in time to avoid territorial fights and eating small fellows.
