Subfamily – Carapace – (Corydoradinae).

Origin: South America ponds of Venezuela.

Sex differences are weakly expressed, although females tend to grow to large sizes, and in mature individuals, the body is noticeably rounder and wider.

Conditions of detention, feeding and breeding, as in most Koridorasov:

An aquarium of 50 liters, filtering and aeration is required to create a weak current of water that simulates natural conditions, corridors live mainly in small streams, ideally using a substrate of fine sand, although rounded gravel is an acceptable alternative.

Another decor is largely reduced to personal preference, you can add a bit of creep and small stones. Living aquarium plants will recreate their natural habitat and will be used by catfish as shelters.

Venezuelan Corridor (Corydoras venezuelanus) peaceful and sociable, is classified as a social species, therefore, in order to fully reveal its characteristic behavior, it should be kept in a group of at least 4-6 individuals.

In the aquarium occupies the lower level.

Calm and peace-loving fish, in neighbors to the Venezuelan catfish it is better to select fish of similar size and behavior (haracin and similar), you need to abandon aggressive neighbors.

Often somik rushes to the surface of the water as he is able to breathe atmospheric air in a manner similar to many labyrinths – this happens when there is a lack of oxygen in the water. Like other members of the family, fish of this genus have additional intestinal respiration and should have access to the surface of the water.

It is necessary to maintain good water quality and regularly clean the substrate; any deviation in water parameters leads to a deterioration of the health of the fish.

Water parameters: acidity within PH 6.0 – 8.0, temperature 21 – 27 ° C, hardness DGH 7-20.

Prefers ambient lighting.

Nutrition: Feeding is not difficult, they are omnivorous and will take any sinking dry food, as well as live and frozen foods, such as bloodworms, tubule and others.

A variety of food will ensure the fish optimal condition.

Reproduction: for spawning, it is preferable to plant a group of fish at the age of 1.5 years (4-6 males and 2-3 females or 2-3 males and 1 female), which are kept separate for a week before, and are fed with vigor and variety.

Spawning, both in general and in a small spawning aquarium with an air filter / airlift.

Frequent addition of fresh cool water stimulates spawning, and lower atmospheric pressure is also a stimulus.

Females begin to swim restlessly, pursued by males. Then one of them becomes sideways in front of the head of the female and emits sperm, while the female at this time lays several eggs into a folded “U” bucket and swims through a cloud of sperm.

The female lays eggs up to 300 pcs on leaves and hard objects. This process is repeated several times and can last from several hours to 3 days.

At this time, it is recommended to feed the fish hard, so as not to starve, because often the female eats caviar.

After spawning, the fish are removed or the substrate with caviar is transferred to the incubator, if the eggs are laid on the glass of the aquarium, then they are carefully removed with a razor.

The incubation period is 3-6 days, the fry swim on the next day.

Starter feed: live dust.

Fry Venezuelan Corridor (Corydoras venezuelanus) very early acquire adult color. Puberty at 8-12 months.
