Shark catfish come from Thailand.The people call it pangasius Siamese, aquarium or Colombian shark. There are two types - aggressive predator (large) and aquarium (small). With proper care, they can grow to 60 cm. Fish reproduce only if they have the appropriate content.
Акулий сом внешне похож на касатку.The head is slightly flattened, the body is long, the mouth with the mustache, the eyes are round, convex and large. There is a dorsal fin, just like a shark, with a tail with two lobes. Look at the look of the young shark catfish in the photo.
Young fish differ from adults in color,From the gills to the tail are two silver edging. The older they become, the fewer the striae. As a result, in adult fish, the color changes to a darker color, and the edging is retained only at the tip of the fins or tail.
Shark catfish - shy fish, which is afraid evenits shadow. But it is very mobile, and therefore in a small aquarium it is quite crowded. There must be so much space for a catfish to be where to go for a walk. For a comfortable environment, aquarium shark catfish should be provided with full-fledged care. The aquarium for young individuals should be large, which contains at least 500 liters of clean water. The older the fish, the more water it needs.
Обязательно нужно приобрести фильтр для очистки.Otherwise, the catfish will develop many diseases. Pay attention to the water temperature. The optimum temperature is from 23 to 28 degrees. You can not pour cold and non-permanent water. Put in the aquarium stones and driftwood large size, but not sharp, so that the fish is not injured, and the plants should be with a thick root system. The bottom is sprinkled with sand or gravel.
Сомы – хищники по натуре, и поэтому у них всегда a good appetite. You need to feed three times a day in the right amount depending on the age of the pet. The menu should contain all useful vitamins and minerals: protein, ground beef meat, lean fish, shrimp, vegetables (cucumbers, cabbage, potatoes), buckwheat or rice porridge. Som will never give up eating, so try not to overfeed. After all, he often suffers from obesity, which is difficult to cure. Twice a week, arrange unloading days, in which the catfish should not be fed.
These are mobile fish, whose behavior is veryit is interesting to observe. When the shark catfish first appears in the aquarium, it will start to rush about in shock and misunderstanding where it is. Even can lie down on algae and pretend to be dead. But before he touches him, he will again notice. This is a shy fish, and will often watch them somewhere near the far wall of the aquarium. If you hear a knock of foreign objects, try to hide in the algae.
Proper care and maintenance will save fish from various terrible diseases. Still, sometimes you can see that the shark has become less mobile. In this case, watch him. Sometimes you can see:
With ulcers, the body is lubricatedpotassium permanganate three times a day. Also, fish can be moved for several days in saline. If some of the fins with the antennae have disappeared, then the wrong treatment is used. Poor nutrition in fish can be at low water temperatures. Fungus is treated with a solution of malachite green. But with redness near the fins, carry the catfish to the veterinary clinic.
This type of fish feels comfortable in the pack.Loneliness is unacceptable for them. However, in the aquarium should not be too many fish. Neighbors should be almost the same size as soma. As a rule, predators sooner or later begin to destroy fish that are significantly smaller than them. After the neighbors are hooked up, always make sure that the catfish is not hungry.
In aquarium shark catfish, spawning begins inJune and lasts until late autumn. Fish are ready for reproduction already at the age of 3-6 years. The couple should be in a separate container, where many algae grow, as the female lays eggs in the grass. For the successful breeding of fish, the temperature of the water should be slightly increased, and at low degrees, fertilization will not occur.
The female catfish can save almost 100,000small eggs, after that a period of incubation occurs during the day. At this time, constantly monitor the temperature, it should not be below 30 degrees. After the appearance of fry, they are transplanted into an aquarium and fed with special food, which is sold in pet stores. With insufficient nutrition, the fish eat the weaker neighbor. At home, shark catfish breed very rarely. But still worth a try. Moreover, they can multiply in the aquarium, if you increase the temperature to the desired degree.
