Somik koridoras-pygmy (corydoras pygmaeus): content, breeding

The pygmy corridor (corydoras pygmaeus) is a representative of the kalliht family and the smallest of bottom catfish living in domestic water bodies. This is a gregarious and peaceful fish, easy to maintain and breeding.

Most often, they are acquired as orderlies of the aquarium bottom, but tiny catfish also have their fans.

Koridoras- a small schooling fish that does not require much effort when breeding

The homeland of pygmy corridors is South America. Fish live in large flocks in silted areas in tributaries of the Madeira River and in slow-flowing streams, occasionally float to the surface to swallow air.

The body shape is elongated, flattened laterally, the line of the abdomen is straight. Fins are transparent, well developed, small antennae grow around the mouth.

The main color is olive with a gray tint. From the eyes and to the base of the tail there is a black stripe, which ends with a spot of irregular shape.

Females are larger and fuller than males, with a rounded upper fin. In males it is pointed. Sizes of fish:

The food corridors are picky and eat any live (tubule, artemia, daphnia) and dry (tablets for bottom fish, flakes, pellets) feed. You can also give lettuce, dandelion or slices of fresh cucumber scalded with boiling water.

The main thing is that the food was small, otherwise, the fish will not be able to swallow it and remain hungry. Feed pets 1 time per day in small portions.

Koridoras loves live and dry food

For a comfortable maintenance of pygmy catfish, you must purchase a flock of 15 individuals. In such a company, the fish look spectacular, show their best abilities and behavioral peculiarities peculiar only to this species.. Rules for the arrangement of the reservoir are as follows:

  1. Aquarium – choose at the rate of 3 liters on one individual. For a flock of 5 corridors suitable capacity for 10−15 liters. If the fish are more than 10, the volume of water space is increased to 50 liters.
  2. The soil is soft (sand or small pebbles) of dark color, without sharp edges. Against its background, the fish will look brighter.
  3. Water temperature – + 22−26 degrees. It is necessary to replace the weekly 1/3 of the water.
  4. pH – 6.5-7.5.
  5. dGH – up to 15.
  1. Plants – necessarily the presence of vegetation planted around the perimeter of the aquarium so that there is enough space for the free movement of fish. Pygmy prefer broadleaf plants – Echinodorus, cryptocoryne, anubias.
  2. Lighting – soft, diffused, reaching from above.
  3. Scenery – a large number of shelters is recommended. It can be grottoes, caves, snags, as well as several mounds of large smooth stones on which fish love to relax.
  4. Aeration and filtration – it is necessary to install an internal aquarium filter with aeration function or a separate filter, because catfish raise a strong turbidity, rummaging around the bottom of the reservoir, and a compressor. Fish, though possess intestinal respiration, but additional aeration will not be superfluous.

At home, somikov koridoras pygmy breeding is somewhat more difficult than other species. They can spawn in the general aquarium, but in the absence of neighbors – lovers eat at someone else’s caviar.

In all other cases, spawners of 10 liters are used.

In order for breeding to be productive, it is recommended to provoke the onset of spawning. To do this, daily change half the volume of water to fresh with a lower temperature (imitate the rainy season) and richly feed the fish with live food.

Females and males are preferably kept apart from each other. Sexual dimorphism at this time is especially noticeable.

Water in spawning recommended soft. The temperature regime is maintained at 2−3 degrees lower than in the general aquarium.

At the bottom spread a special substrate for spawning, strengthen the plants in it and install a sponge filter to prevent the fry from being sucked inside.

The lighting is muffled. One of the walls of the otsadnika should be lit brighter.

Additional glass is leaned against it, where the female will attach the roe (it will be easier to move it later to the incubator).

In the prepared tank are planted 2−3 females and several males, which are deposited immediately after spawning. The female lays up to 100 eggs, which attaches to the leaves of plants or glass.

Pygmy females are deposited immediately after spawning.

After the end of the spawning, it is necessary to remove whitened unfertilized eggs and fungi coated with eggs. Experienced aquarists sit in a spawner a certain type of shrimp, eating only infected caviar.

They ignore healthy eggs. One option is shrimp-cherry.

The incubation period lasts about four days, after which the larvae hatch, which after 3-4 days begin to swim and feed on their own.

They feed young fish with live dust, ciliates or egg yolk, gradually switching to young Artemia. As they grow older, they begin to give various chopped feeds.

A balanced diet and proper maintenance of the pygmy corridor in the domestic water reservoir contribute to the activity and good health of pets, who will fly around the aquarium with a funny flock, infecting other underwater inhabitants with their optimism.
