Arrangement and parameters of the aquarium: corridors of fish are gregarious and more comfortable in the amount of 4-8 individuals. A flock requires a 50-70 liter capacity.

In the aquarium, you need a lot of shelters from coconut shells, snags, decorative grottoes.

Fish love dense vegetation, but you need to choose species with strong roots so that the corridors will not dig them. Floating plants can also be used, but so that they do not completely cover the surface of the water.

Breathing fish need to periodically swallow air near the surface. The ground should be shallow and without sharp edges, about which catfish can damage tender antennae.

Water parameters: 24-28 ° C, GH 5-15, pH 6-7.6.

Water changes are carried out at 25-30% weekly. Lighting scattered.

Sterba Corridor (Corydoras sterbai) extremely sensitive to increased concentrations of copper and salt in water, an excess of which can lead to the death of fish.

Somiki are very peaceful, although they still eat caviar of other fish, but are not aggressive towards adults. Suitable carp neighbors, characteristic, labyrinth, dwarf cichlids, iris irises.

It is not recommended to keep with large and aggressive species.

Nutrition: are omnivorous and take sinking food for bottom fish, dry mixes. From live and frozen feed, Artemia, bloodworms are preferred, and the pipe worker is especially loved.

They feed at the bottom, although sometimes they rise to the surface to get food.

Reproduction: Sterb catfish can breed in a small spawning 10-20 liters. If the fish are large, the size of the tank should be increased.

A female and two males or a group of fish in the amount of 6-9 individuals are placed for spawning. Males should prevail in the flock.

Fine gravel or sand will be suitable as soil, but even without it you can do to keep the water clean. The substrate is Javanese moss, it does not hurt to place in the spawning one large-leaved plant with strong roots. The filter should be with a sponge so that the larvae are not sucked.

Peat water is useful.

Water parameters in the spawning aquarium: 24 ° C, GH 4-6, pH 6.5.

To feed the producers before spawning you need plenty of different types of feed. Stimulate spawning frequent water changes in the amount of up to 70% for a cooler one, raising the water level in the aquarium.

The readiness of the fish for spawning can be determined by the males, which are beginning to actively pursue the female.

The female attaches 1-4 whitish-colored eggs to glass and plants, often in places where the flow of water is high enough and able to sweep from 30 to 1000 eggs, depending on her size and age. Large caviar – about 2 mm.

The corridors eat caviar, so immediately after spawning, the adults settle out or the eggs are transferred to another container, but always with water from the spawning ground, then you should add a few drops of methylene blue.

Caviar affected by fungus should be removed. Some aquarists even use certain types of freshwater shrimp (Neocaridina heteropoda), they eat sick (fungus-infected eggs), but leave healthy intact.

The larvae hatch after a week, and after another 48 hours they are able to feed. Starter feed – phytoplankton, zooplankton, ciliate, later you can add to the diet Artemia.

Catfish grow quickly and by the month of age their length is already 1 cm. By two months, adult color begins to appear.

Mature somiki Sterba Corridor (Corydoras sterbai) become in 1 year, but for some the process is delayed up to 2 years.
