Motley catfish corridor compatibility: any fish. Only not desirable – Labo, modest fight, well, and antsistrus, because they chase them (although this is more like a game).

In addition, it is not advisable to contain them with large and / or aggressive cichlids.

Useful tips: Perhaps the most famous catfish and excellent attendants of the aquarium, by planting them with “Golden Fish” you will ensure the purity of the soil in the aquarium.


Mottled koridoras lives in South America.

The corridor has a speckled body of small size with a convex back, covered with a shell, which consists of two rows of bone plates located on the sides of the body. The body has a gray-olive color with numerous dark spots.

The abdomen is pinkish with a golden sheen. There are also albinos. Males are smaller than females, color is paler, body spots are not smaller, dorsal fin is high and pointed at the end.

In length, the male reaches 4-6 cm, and the female – up to 7 cm. Life expectancy in the aquarium is 8-10 years.

Data som keep in the aquarium is not difficult.
As the soil, it is desirable to use sand. It is necessary to have a large number of shelters in the form of stones, koryag or grottoes where fish could hide and rest.

Water parameters for the maintenance of speckled catfish corridor

– temperature 24-26 ° С, dGH 4 °, pH 6.0-7.0. Water filtration is required and a weekly replacement of 1/5 of the total volume of the aquarium is desirable.

The quality of aeration fish undemanding.

Corridors besides gill have intestinal respiration, therefore it is desirable that the surface of the water is free from plants, so that fish can freely swallow fresh air.

The fish are very peaceful, calm. They slowly swim along the bottom in search of food.

In the aquarium they are usually kept in flocks. Fish, do not pose any threat to other inhabitants of the aquarium.

Fish feed on all kinds of food in the form of flakes and pellets, dry food. Corridors take food only from the bottom.

Feeding any aquarium fish should be correct: balanced, varied. This fundamental rule is the key to successful keeping of any fish, be it guppies or astronotuses.

Article “How and how much to feed aquarium fish” talks in detail about this, it outlines the basic principles of the diet and feeding regime of fish.

In this article, we note the most important thing – feeding fish should not be monotonous; both dry and live food should be included in the diet. In addition, you need to take into account the gastronomic preferences of a particular fish and, depending on this, include in its diet ration either with the highest protein content or vice versa with vegetable ingredients.

Popular and popular feed for fish, of course, are dry food. For example, hourly and everywhere can be found on the aquarium shelves of food company “Tetra” – the leader of the Russian market, in fact, the range of feeds of this company is striking.

In the “gastronomic arsenal” of Tetra are included as individual feeds for a certain type of fish: for goldfish, for cichlids, for loricarids, guppies, labyrinths, arovan, discus, etc. Also, Tetra has developed specialized foods, for example, for enhancing color, fortified or for feeding fry.

Detailed information on all Tetra feeds, you can find on the official website of the company – here.

It should be noted that when buying any dry food, you should pay attention to the date of its production and shelf life, try not to buy food by weight, and also keep the food in a closed state – this will help avoid the development of pathogenic flora in it.

Aquarium fish somiki: corridors and the smallest catfish

Common catfish, speckled, corridor – all these names refer to the representatives of the kallichtovy family, or armored somikov. This species inhabits freshwater bodies with dense vegetation of Brazil, Paraguay, Argentina and other countries of South America.

Many of the representatives of the corridor view have taken a firm place among experienced aquarists and amateurs due to their interesting behavior, unique appearance and unique coloristics.

It is not possible to list all representatives of somik-corridors in one article, therefore we focus only on those who have gained great popularity among aquarists.

The presented types of corridors should be grouped in 5-20 pieces. The size of a specific aquarium for catfish should be at least 54 liters, with the content of the same flock in the general aquarium, the volume should be at least 160 liters, except for panda cats that need a smaller volume of the total aquarium – 112 liters.

Females are distinguished by a larger size and width of the back. And only two species have other, more pronounced differences – the males of the corridor are more miniature than the females and have a clearer pattern, while the males of the speckled catfish are much smaller and sleeker.

The diet for all presented types of corridors is recommended to be made from dry, frozen and live food.

  • Variety of species

The corridors are cute, active and peace-loving fish, moreover, unpretentious to the conditions of detention. That is why they are a great option for beginning aquarists.

The belonging of the fish to the genus Koridoras is determined by the short, short body with a convex back along which there are two rows of overlapping bone plates. Three pairs of antennae help corridors to orient themselves in muddy water.

Somiki corridors can breathe air. To do this, they swallow the air bubble, and the absorption of oxygen occurs through the digestive tract.

Corridors live almost throughout South America. They live in fresh, very soft water with low acidity (from 6 to 6.5), often in “black water” with a high content of rotting products of plants, showing a strong antibacterial effect.

In their native environment corridors live on a muddy, less often – sandy bottom.

The water temperature usually ranges from 22-26 degrees, but some southern species also live in cooler waters, so they normally tolerate a decrease in temperature up to 3 degrees Celsius.

Speckled catfish (as they also call corridors) contain flocks of at least 5-6 individuals. A group of 6-8 corridors feels more confident and free.

Sand for the aquarium choose fine, fraction of 1-3 mm, without sharp particles that can injure the antennae. Small fishes like to hide under unsharp stones and snags, therefore it is important to equip some peculiar shelters.

If the aquarium is densely planted with plants, it is important to leave at least a small section of free ground from which it will be convenient for corridors to lift food.

The content of corridors in salt water is unacceptable, the possible maximum salt is 1%. It is important to minimize the amount of nitrite, nitrate and ammonium nitrogen in the water.

Corridors grown in captivity are less demanding in conditions of detention than wild animals.

Corridors are called sweepers because they are omnivores and pick up any food from the bottom. However, if there are other fish in the aquarium, it is important to ensure that the required amount falls to the bottom, otherwise catfish will starve.

At the moment, there are about 150 species of catfish of the corridor, most of which successfully contain and breed in captivity. Here is a list of the most interesting and popular.

Motley corridor. The nominal form is the most unpretentious of all known catfish species and in general aquarium fish. They withstand temperature drops from +3 to +30, can live for a long time in an aquarium without aeration, carry a large amount of organic compounds in water.

Vualevaya and albino breeding forms are a bit more capricious. The speckled corridor is distinguished by a high dorsal fin.

The female is much larger than the male, sometimes twice as large, with a shorter rounded fin.

The golden corridor has a golden strip along the back. There are several color forms: nominal with bronze, albino, black and others.

Golden corridor, like other species, unpretentious to the conditions of detention, requires only a stable temperature in the range of 22-26 degrees.

The panda corridor grows up to 3-4 cm. With a lack of live food, the panda remains shallow. White to pinkish-white, on the eyes, dorsal fin and at the tail of the panda has large black spots.

Like all other corridors, a panda is simple to maintain: he needs only pure, slightly acidified water with aeration and a temperature of about 22 degrees.

Somby’s catfish grows up to 5 cm. It is covered with sterna by a dense dot pattern, which passes into parallel stripes on the tail. Adult shterby are distinguished by bright orange belly fins and front rays on pectoral fins.

Sterba Corridor changes color tone depending on the color of the soil.

Adolfi Corridor is a very interesting catfish up to 5 cm long. The little body is white, there are black stripes on the eyes and back along the back, a bright orange spot on the back of the head.

In captivity breeds badly.

And these are just crumbs. It is worth mentioning also the once-popular, but by the spotted trilinear and elegant catfish, the slim black-and-white two-striped arcuatuses that have almost disappeared from the domestic market. The interest of the amateurs is also directed towards miniature pygmies, Hastatus with a black cross at the tail, Habrosas with leopard coloring.

Not to mention the slave catfish: the adults are unremarkable, but the young – bright, with an orange head, a black body and a white tail – just can not be confused with any other.

Sterba Corridor is a schooling fish that feels comfortable in the company of 5-10 relatives. It is a bottom aquarium fish, prefers a wide area of ​​the bottom.

Choose for a settlement a low and long aquarium with a capacity of 50 liters or more.

Watch the games of the Sterb Corridors.

Fish prefer warm water, so the temperature of the content in the tank should be in the range of 25-28 degrees Celsius. Acceptable acidity threshold – 6.0-7.0 pH, hardness – 15 dH. Do not like salted water – this also applies to treatment with salt.

Water changes are recommended every 7 days, renewing 30% of water.

The Sterba Corridor loves to sort through the soil substrate, so install a quality filter in the aquarium. Sterba can breathe atmospheric oxygen, trapping air from the surface, but aeration of water is also required.

Cover the aquarium with a lid, leaving a gap between it and the surface of the water. Do not pour water to the brim to allow oxygen to flow freely into the water.

Land in the tank broadleaf plants – Echinodorus and Anubiasa, and leave room for free swimming. As a soil, choose a substrate with a fine fraction – pebbles, sand or gravel, which will be easier to plow. Fix the plants with stones so that they are not dug out.

Lighting is better diffused, dim. Install enough shelters in the aquarium so that catfish can hide from annoying neighbors.

Recommended decorations – snags, caverns, grottoes, clay pots.

Feeding catfish is not difficult – they are unpretentious to food. Prefer live and dry food.

Bloodworm, daphnia, tube maker, plant food suitable for them. Like bottom fish, sterba corridors should receive enough feed to take it from the bottom.

Make sure that other fish do not have time to eat everything, or feed catfish with sinking granules.

As neighbors, small and peaceful fish are suitable for somber catfish: other types of corridors, petilia, iris, rasboru. Sterba can eat fry and spawn of other fish, therefore spawning should take place in a separate tank.

These fish themselves can become victims of attacks from larger neighbors, consider this when settling. Do not get along with territorial, aggressive species – cichlids, swordtails, barbs.

Comic corridor aquarium: care and reproduction (photo)

Somiki aquarium corridors have a slightly elongated body, medium-sized fins and stigma with four antennae. Since this is a bottom fish, her mouth is at the bottom.

Their color is very diverse. Among other things, it is often possible to meet albino catfish.

The body of these small fish is covered with bony scales, which is why they are also called shellfish. Interestingly, the fish belonging to this species have two types of respiratory system – gill and intestinal.

To distinguish the female from the male corridor is easy. Its coloring is not so bright, and the dorsal fin has a rounded shape.

These fish with an unusual appearance reach a length of no more than 5 cm. In nature, they can be found in the tributaries of the Ucayali River, located in Peru.

The flow here is slow, and the water is saturated with oxygen.

Comic corridor panda is immediately remembered for its interesting color, which has some similarities with Chinese bears. The fishes have a light body, and on the fins and around the eyes there are three black spots: the first is on the head, the second is near the tail, and the third is at the dorsal fin.

Males, unlike females, have smaller sizes and a slightly different body shape. The newly born fry have a single high near-melt fold and rather large pectoral fins.

Somiki panda – this is a brave fish that in their shelter can perfectly keep the defense. In addition, they are not afraid to swim even to the largest inhabitants of the underwater world in search of food. Therefore, you can safely settle such catfish in a common aquarium.

But still it is worth thinking before putting them in a tank where too aggressive fish live.

Pandas corridors are especially active when the aquarium is heated to 28-30 ° C. Their fun and funny bustle can be observed by filling the container with sourish water at room temperature.

Decorative pond for catfish should be well filtered and often change the water in it. Despite the fact that the fish are quite unpretentious, they do not like to have too much dissolved organic matter and mechanical suspension in their habitat.

It does not matter what will be the filtration of water, as long as it is regular.

Females are distinguished by their large size, more rounded sides and the line of the abdomen, which has an arched profile. In addition, there is a difference in the form of fins located on the abdomen.

They are somewhat rounder and larger than those of the males.

This is the name of the bottom fish received due to its color. Comic corridor golden has a calm and peaceful nature. He perfectly gets on with almost any aquarium fish.

The whole body of the catfish is covered with rows of strong bone plates, which make it practically invulnerable to larger and more aggressive individuals. But it is best to keep representatives of this species in the same container with fish of the same size.

Golden corridors feed from the bottom of the aquarium, while eating what others have not eaten. With such catfish, there is almost no residue left at the bottom.

They are omnivores and love both dry and live food.

Golden catfish do not like too bright lighting. That is why during the day they usually sit in the shade of stones and snags or in shelters, and at night they become very active.

Since these fish are quite unpretentious, they are very fond of novice aquarists. Like somiki pandas, they have not only gill breathing, but also intestinal.

Therefore, sometimes they float to the surface to breathe atmospheric air. You can equip the aquarium with a special filter pump.

It will purify water from turbidity and aerate it. As a result, golden catfish will very rarely float to the surface, since it will be enough for them to breathe the oxygen that is in their habitat.

It should weekly replace the water in the tank about 15-20% of its total volume.

The female of the golden corridor is noticeably larger than the male, and its maximum length reaches 7.5 cm. Another distinctive feature: the body of the female individual is wider than in the male fish.

Sometimes they are distinguished by the shape of the fins. For example, the male has a sharp dorsal fin, and the female has a rounded fin. The albino form of golden catfish is very rare.

With proper maintenance, corridors can live in aquariums for about 10 years.

The fish “corridor panda” is deservedly popular with aquarists. Catfish belongs to the family of armored catfish. The second name of this family is Kalliht.

A distinctive feature of all the fish belonging to it are two rows of bone plates running along the body. They provide these small fish with excellent protection against predatory or simply aggressive fish of other species.

Homeland catfish pandas – Ecuador and Peru. Fish live in rivers with relatively cold water: Rio Ukuyali, Rio Aqua, Rio Amaril.

In 1968, the species was first described, and later got its name – the corridor Panda. The name very aptly describes the appearance of this pet aquarists. The light body and the prominent black circles around the eyes and around the caudal fin give it a noticeable resemblance to the famous bear.

Due to the cute appearance, simplicity of keeping and breeding, catfish Panda very quickly became popular with aquarists.

Despite the fact that the fish corridor is a tropical temperature range, it is comfortable enough for it to be wide enough: from 16 to 28 ° С. Somica panda is relatively painless able to tolerate short-term lowering of temperature up to 12 ° C.

It is very important that the water is clean. Neutral or slightly acidic water will do.

Watch a video on how to breed, feed and maintain catfish.

The optimal ground for these catfish is fine sand or gravel. In the aquarium should be enough vegetation. The oxygen content should be high enough.

This means good aeration is required. Catfish will feel good with a sufficient number of shelters.

It can be a variety of snags, stones, grottoes, pots and the same aquatic plants.

Buying corridors you need to remember that the fish is gregarious. Comfortable conditions for it will be the existence of a group of 8 individuals.

A lonely corridor is unlikely to live long. These fish will get along perfectly with any other peaceful neighbors. Boths, rasbory, tetras and other similar fish will get along well with them.

By the way, the corridors of another species are quite capable of joining a flock of pandas.

But sharing content with large neighbors or barbs is undesirable. The former may begin hunting for these rather small fish, while the latter are able to pluck their fins, which will significantly impair the appearance of the pandas, and they will not take pleasure.

Particularly affected by the snooty barbus vualevaya form catfish panda.

In the food corridor completely picky. Since the fish is bottom, it eats almost everything that sinks to the bottom from the surface.

But to ensure a complete diet, it is worth giving these som special food tablets. Fish eat them with pleasure.

They will not refuse from live food or frost. Tubber, bloodworm, daphnia can pleasantly diversify the diet of your fish.

It is better to give food to pandas in the evening or at night, because they are mostly nocturnal.

Look at how two different corridor types get along well: the panda and the shterba.

Somik speckled – the most popular catfish in the aquarium

The speckled corridor, better known as the speckled catfish, is the most popular and widespread catfish of the entire genus. Competition to it can make unless Corydoras aenus or a bronze corridor and still catfish. Catfish grow small, males up to 6.5 cm, and females up to 7.5 cm.

The body is squat, covered with bony plates, from which its scientific name derives. On the upper jaw there are two pairs of whiskers with the help of which the catfish finds food at the bottom.

The body color is pale olive with a green or blue iridescent sheen. A scattering of dark spots is scattered throughout the body, and is never repeated in two individuals at once.

The fins are transparent, on the dorsal fin a dark stripe running along the first ray. Various albino and golden forms are derived.

Catfish caught in nature have greater contrast in the spots, and brighter colors than those that are divorced in the aquarium. This is due to prolonged maintenance in other conditions and cross-breeding with relatives.

Life expectancy on average from 3 to 5 years, but depends on water temperature. The higher it is, the faster the metabolism and shorter life.

An interesting feature of this species is that catfish can make sounds due to the movement of their pectoral fins. As a rule, young people make sounds when scared, or a couple during spawning.

Like other corridors, speckled sometimes rises to the surface to get oxygen. They can breathe atmospheric oxygen, capturing it from the surface and dissolving it in the intestine.

From time to time they rise behind it, but if this happens too often, it is possible that there is a low amount of dissolved oxygen in the aquarium and you need to turn on aeration.
Like many species of catfish, speckled ones have sharp spines under the eyes, below the fat fin, and on the dorsal. They prevent the larger fish from swallowing it.

However, when transplanting catfish they may get confused in the net, it is better to use a container or a net of dense tissue.

Catfish is very peaceful and active throughout the day, although it can sit in one place for a long time, looking for food. It is best to keep speckled packs, as they prefer to live in a group.
