Somiki corridors: types, care and maintenance in an aquarium

Funny catfish corridors enliven the aquarium space. They float flocks, rush one after another, play catch-up. Homeland of these funny fish – South America.

There they live in fresh water with warm soft water and a silty bottom. Small fishes are unpretentious in leaving, even the beginning aquarist will cope with them. There are more than 150 types of corridors that differ in color, size and behavior.

The conditions of their content have some peculiarities.

Somik koridoras active beautiful fish

Corydoras is a small fish with a flattened body. She has a curved back and a flat belly. The scales are replaced by bone plates, so the fish is sometimes called an armor-clad catfish.

The mouth is at the bottom, as the fish produces food at the bottom. On the lips there are 3 pairs of mustache, which help the catfish to navigate in muddy water.

The body length of the corridors is from 3 to 10 cm. Life expectancy reaches 15 years. In catfish double respiratory system.

They absorb oxygen not only from the gills, but also from the intestines. Somiki swallow air bubbles, which are absorbed by their digestive system. Coloring in fish is the most diverse, albino is quite common.

Females differ from males in less intense coloring and a rounded dorsal fin.

Among the variety of types of corridors, only some of them are contained in the aquarium. The most popular are:

  • Mottled. These are individuals up to 8 cm long, with females much larger than males. Somiks are very unpretentious – they can live in turbid water with virtually no aeration and withstand water temperature fluctuations from 3 to 30 ºС. There are voile speckled catfish, as well as albinos. These fish are more demanding of conditions.
  • Golden. Representatives of this species are found in the rivers of Venezuela and Trinidad. They are distinguished by a golden strip along the ridge. The body length of fish does not exceed 7 cm. They are as unpretentious as speckled ones, but they cannot tolerate large temperature fluctuations. The optimum mode is from 20 to 26 ºС.

There are several types that differ in color and slight deviations in care.

  • Panda. These fish come from Peru. Their length is 3-4 cm. They have a white color, sometimes with a pinkish sheen. There are black spots on the fins, eyes and near the tail. The more fish gets live food, the larger they grow. Somiks of this species prefer slightly acidified clear water with good aeration and a temperature of 22 ºС.
  • Sterba They are up to 5 cm long. Their torso is covered with small spots, which pass into parallel stripes near the tail. Fins on the abdomen are orange, and the pectoral fins have rays. Fish have the ability to mimicry, that is, they can change color depending on the color of the bottom.
  • Adolf. Small individuals up to 5 cm long. They have a white body and an orange spot on the head. On the back are black stripes, calling on the eyes. This species does not spawn in aquariums.
  • Leopard. It has a spectacular yellow-brown color, resembling the skin of a leopard. Body length does not exceed 6 cm.

Somics can not stand loneliness and prefer to live in flocks. They contain groups of 5−8 individuals.

The corridors are good attendants of the aquarium. Most often they are located in the lower layers of water or on the surface of the ground, where they are looking for food that has fallen from above.

They are engaged in searches very actively and raise all the murk from the bottom, so you need to install a powerful filter in the aquarium.

Aquarium catfish corridors have a peaceful nature. They get along well with neighbors such as:

  • barbs;
  • cockerels;
  • guppy;
  • mollies;
  • gourami;
  • swordtails;
  • angelfish;
  • discus and others.

Somiki peaceful aquarium inhabitants and get along with many fish

When kept together with goldfish, koi carps and astronotus conflicts may arise. Somikov can not be settled with cichlids of American and African species.

Somiki corridors belong to the bottom fish. For them, the priority is the area of ​​the bottom of the aquarium. When calculating use the following rules: for every 20−25 cm of the total length of the bodies of catfish need 0.5 m² of area.

Usually a flock of 5−8 fish contain in a 50-liter aquarium.

Main in the conditions of the content of corridors the required area of ​​the bottom of the aquarium

Water suitable for catfish has a wide range of parameters, so they can be settled with both tropical fish and inhabitants of cold waters. Somics can live at water temperatures from 20 to 30 ºC, hardness from 0 to 18 dH, acidity from 5.8 to 7.8 Ph, but the best for them would be the following conditions:

  • temperature from 20 to 26 ° C;
  • hardness from 0 to 12 dH;
  • acidity from 6.4 to 7.4 Ph.

Great importance is the content of nitrates and nitrites in the aquatic environment – it should be minimal. For the treatment of fish and the destruction of parasites can not be used table salt – the corridors do not tolerate it.

As aquarium soil used fine sand or gravel. It should not be sharp pebbles, on which the fish can get hurt.

To somiki looked especially impressive, it is better to use a dark ground. The bottom is decorated with snags and rounded stones in which the fish will hide.

Do not use products made of polymeric materials that will release harmful substances into the aquatic environment.

The bottom of the aquarium should be of fine sand or smooth gravel so that the fish will not hurt in search of food.

Plants can be planted in an aquarium, but there should be enough space between them so that catfish can freely search for food. For registration fit moss, fern and algae in the form of branchy bushes.

Somiki can undermine their roots, so you need to choose plants with an extensive root system or fix them in the ground. Water algae should not overly close the surface of the water.

The corridors are omnivorous, they pick up leftover food from the bottom. But you can not leave catfish on one “grass” feed, as they will starve.

Dry feed for bottom fish will be suitable, as well as live and frozen bloodworm, Artemia, tubule, daphnia, coretra, and also include tablets with a vegetable composition in the diet.

The corridors become sexually mature at the age of 12–18 months. For spawning you need to equip a separate tank with a capacity of at least 60 liters.

Broad-leaved plants are planted there, the bottom is decorated with snags and flat stones. The water temperature should be one to two degrees lower than in a normal aquarium.

Although somiki corridors and omnivores should not be neglected special food

One female and several males participate in spawning. The males chase the female around the aquarium, after which she chooses one of them and takes his milk into her mouth. At this time, she lays several eggs in the pelvic fins, folded in a bag.

Then the female chooses a smooth surface (usually it is a stone, glass of an aquarium or snag), lubricates it with milt and sticks eggs. The same is repeated with other males.

Sometimes males eat deferred eggs. To avoid this, they are distracted by a small amount of food or deposited in a common aquarium.

After 7−10 days, the fish are again ready to spawn. It can last for a whole year.

A week after spawning fry appear. As a starter feed for them use “live dust”.

After 4 weeks the young can be launched into the general aquarium.

In order not to be disappointed in breeding somikov corridors, you need to buy healthy individuals. When buying, observe the following rules:

  1. Choose only vigorous, active fish. Individuals lying on the bottom and not responding to customers, should not be taken.
  2. When choosing, pay attention to fish breathing. A healthy fish quickly rises to the surface, swallows air and vigorously descends. The patient rises with difficulty and falls down like a stone.

When choosing somikov need to follow some rules

  1. If the fish moves sideways or jumps, poorly orientated in space or has problems with balance, then you should not take it. Such an individual is unhealthy.
  2. If the fish have unusual growths or spots on the body, this means that they are affected by the fungus. Reddish spots in the lower body indicate a bacterial infection.
  3. Do not take an individual with a damaged mustache.
  4. The fins of the fish should be whole and straightened. You should not buy an individual whose fins are stuck together or have stripes.
  5. Catfish eyes should be clear, not clouded, not sunken and not too convex.
  6. You can not buy individuals covered with mucus or sore gills. If the gills of the fish turned black, then she was poisoned by nitrogen.
  7. If the abdomen in the fish is hollow, then this individual is too depleted or infected with worms. If it is too convex, it may be due to various diseases. Such fish should not be bought either.

You should not buy catfish of the same size, otherwise you risk acquiring individuals of the same sex. Purchased fish can not be immediately released into the general aquarium.

Some time they should be held in quarantine.

In order to purchase a sexually opposite pair of catfish, you should choose fish of various sizes

Somiki corridors are active fish that clean the bottom of the aquarium from dirt. They are unpretentious to the conditions of detention and easily multiply.

With proper care, they will maintain health and live a long life.
