Corridor speckled catfish: content, compatibility, breeding, photo-video review

Corydoras paleatus Corridor speckled catfish

Order, family: armored soma.

Comfortable water temperature: 24-25 ° C.

Ph: 6.0-7.0.

Aggressiveness: not aggressive.

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.

  • The content of the corridors in the aquarium
  • Multiplication corridors
  • 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.

In this article, we will talk about very original armored catfish with the interesting name of the corridor Panda. They were first described by Randolph Richards in 1968, and after 3 years they were given the second name because of the great external similarity with similar mammals. The fish were not very difficult to maintain and successfully reproduced.

All this ensured their popularity among aquarists, which continues to this day.

The homeland of the Corydoras panda is considered to be South America, or rather Peru and Ecuador. Somiki inhabit the rivers Rio Aqua, Rio Amaril and Rio Ucayali. They originate in the mountain Andes and are filled by melting snow.

The water in them is cold, clear, soft and sour, slow-flowing, contains a lot of oxygen. The soil consists of fine gravel and sand.

All the bottom is thickly covered with plants.

These representatives of the Kalikht are dense, laterally compressed body with a high back. Both sides cover the horny scales that protect the host from predators.

On the head are large eyes and lower mouth. Three pairs of antennae are visible around it.

There is also a fat fin.

The whole body can be painted in a light, sometimes pinkish color. You can clearly see 3 black spots on each side:

  • the first around the eye (it gives the fish a resemblance to a panda),
  • second on dorsal fin
  • and the third at the base of the tail.

All fins are yellowish white. Males from females are easy to distinguish.

They are smaller and have a pointed fin on the back, while the “girls” are larger, their body is slightly higher, and the fin on the back is rounded.

The average size of the fish is 5.5 cm. A maximum of 15 years can live.

There is also a veil species, which differs only in the length of the fins.

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.

Spawning or breeding of somics.

In the photo, the sex differences of the male and female speckled catfish of the corridor

The female ready for spawning will become noticeably thicker, and in general the fish will become more active. In the female, the belly may take on a reddish hue, and the first ray of the pectoral fin may also turn red. At this point, it is necessary to replace a large amount of water in the spawn (about 30%), with water at which the temperature is lower.

Replacing water with a temperature drop of 5 degrees simulates the rainy season in nature. And it serves as a trigger for spawning.

If spawning did not start within one to two days, repeat the process again.
Spawning speckled catfishsimilar to spawning all the corridors.
Initially, the male stimulates the female with his antennae, tickling her on the back and sides. Then the male adopts the traditional T shape of the corridor. In which his body forms a right angle with respect to the nose of the female.

At this point, he releases milk. To this day, there are disputes about how the eggs from speckled fertilized.

Some believe that the female swallows milt, passes through the intestines and releases to the eggs, which holds in the ventral fins.
Others believe that the milt is released into the female’s mouth, and she, passing it through the gills, sends along the body to the calf.
As soon as the egg is fertilized, the couple splits and the female glues the egg to the surface that she chose and cleaned. It can be glass, filter, plants.
As soon as the egg is laid, the male begins to stimulate the female again and the mating ritual repeats. This continues until two or three hundred eggs are fertilized and glued in the aquarium.

Spawning lasts an hour or so. As soon as spawning is over, parents should be removed from the aquarium, as they can eat caviar. Approximately 6 days the caviar will ripen, although the term depends on the temperature, the warmer the water, the faster.

Cool water can extend up to 8 days.
As soon as the fry starts hatching, it can be fed with very small feeds: cyclops, Artemia larvae, a microworm, or branded feeds ground to dust. It is important to maintain a clean water change.

These aquarium fish are different extreme simplicity. The optimum water temperature in an aquarium can vary from 18 to 28 °, however, for a short time, a significant departure from this range is possible.

The amount of oxygen in the water is not significant; these catfish can use atmospheric air for breathing, but unlike labyrinth fish, oxygen is absorbed in the colon.

Food fits almost any. And I had cases when speckled catfish collected dry daphnia from the surface of the water.

But of course, you must of course use food falling to the bottom. Water parameters do not play a role, but it should not be salty.

These catfish can not tolerate salt, including in the treatment of other fish in the general aquarium.

As mentioned above, filtering water is necessary, since the other inhabitants of the aquarium and the plants will be the first to suffer from the turbidity. Schooling fish, so it is better to contain 4-5 pieces.

You can use any peaceful fish of approximately the same size as neighbors. Guppies, platies, neons will do. The volume of the aquarium from 30-50 liters.

It is desirable to have shelters or thickets of plants where catfish can hide from pesky neighbors. The soil is preferably small, allowing to rummage in it.

Corridor Description.

Somik Koridoras is characterized by a short body with scales, having the form of plates arranged in two rows, which resemble a “shell”.

Fish have a convex back and straight belly. In males, the dorsal fins are pointed, while in females they are rounded.

From the tail fins to the gills, you can see a very noticeable dark green shiny strip, and a golden strip runs in front of the head.

Mouth. At the bottom of the head they have a mouth that has two pairs of sensitive antennae. They serve as an additional body of touch for them, with the help of which somics find food at any time of the day.

The catfish’s belly is yellow, and the back and head are distinguished by a dark brown color. The color of the fins is slightly yellowish and transparent.

The female can reach up to 7 cm. The male looks sleeker due to the smaller size.

Corridor Behavior.

Somik Koridoras – bottom fish, suitable for keeping in common aquariums. Looks good in a large decorative aquarium and pool.

They help get rid of detritus, covering the bottom, due to “plowing up” of the bottom, they use clean sand.


Corridor panda (Corydoras panda) or as it is also called catfish panda, a resident of South America. It lives in Peru and Ecuador, mainly in the rivers Rio Aqua, Rio Amaril, and in the right tributary of the Amazon – Rio Had. Catfish habitats are known for their soft and sour water, with a slow flow.

In addition, the water in them is slightly colder than in other rivers of the region. The species was first described by Randolph H. Richards in 1968.

In 1971 he was named after a large panda, which has a light body and black circles around the eyes, and which catfish resembles in its coloring.
When the species appeared in amateur aquariums, it quickly became very popular, especially after successful breeding attempts.

As mentioned above, catfish panda got its name for its similarity in color with the famous giant panda. The panda corridor has a light or slightly pink body with three black spots. One begins on the head and surrounds the eyes; it is this similarity that gave the catfish a name.

The second is on the dorsal fin, and the third is located near the caudal fin. Like other members of the corridor genus, the panda has three pairs of whiskers.
Adults reach 5.5 cm in size, females are much larger than males and more rounded. There is a voile catfish panda, differing only in the length of the fins.

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.
