Cardinal fish – keeping, care and breeding in an aquarium

Hello readers of Aquablog! The cardinal fish lives in mountain streams of Southeast China.

For the first time the cardinal was brought to the territory of Europe in 1938. Over the years, the fish became so popular with aquarists that the veil form was bred.

They called the fish cardinal afterwards, that there is a red stripe in its color. Due to its durability, this fish is one of a kind that can withstand wild changes in water temperature – from 15 to 30 degrees Celsius.

The cardinal is the owner of a fairly slim and elongated body, flattened on the sides. The location of the mouth upper.

The tail plate is divided into two blades. The back is painted in a brown-olive color, belly with a silvery sheen.

Along the entire length of the body passes a narrow shiny strip of golden color, along the edges of which there are two blue-green stripes. The tail stem has a dark speck, around which the zone is red.

The dorsal fin is lemon yellow in color and also has a red border.

Similar coloring in the abdominal and anal fins, only gill transparent. The tail fin is of a reddish shade and has yellowish stripes. When the cardinal grows to 5 mm, a luminous blue stripe appears on his body on the side, which then disappears when the fish reaches puberty.

Sex differences: male abdomen flat and brighter fins. The females have a rounded belly.

The cardinal fish in aquarium conditions grows up to a maximum of 5 centimeters and live in it for up to two years.

Cardinals are considered peaceful and non-aggressive aquarium fish, which are recommended to be kept in flocks of 6-8. They get along well with ternetii, red neon, rhodostomusami and danios. Basically, the cardinals are kept in the upper layer.

You should not have any difficulties with the maintenance of this aquarium fish. Prepare a small jar, based on the proportion of 15 liters of water per pack of up to 7 pieces.

Make a water level in the aquarium 25 centimeters.

Aquarium soil can be used in the form of river sand, which must be processed before being laid in the aquarium. It is also possible to use small pebbles as a substrate. It is also recommended planting aquarium plants, but not very thick.

As a rule, they put an elodea, a people, a hornpole or a vallisneria into an aquarium. Parameters of aquarium water in an aquarium with cardinals should be as follows:

  • rigidity; 4-20;
  • pH: 6.5-7.5;
  • water temperature: 18-21 degrees.
  • filtration and aeration of the aquarium are required.
  • weekly changes up to 20%.

There is a cardinal live and dry food. Perfectly eats cyclops, bloodworm, dry daphnia.

In nature there is almost all the time small insects.

Cardinals become sexually mature at 4 months of age. It is possible to breed this fish both in the spawn and in the general aquarium.

If you breed small fish in a common bank, set the separator net to the bottom. Spawning is also necessary to equip a bright light and lay on the bottom of dark sand.

Plant aquarium plants with thin leaves along all the walls. Aquarium water in spawning should have the following parameters:

– rigidity; 4-15

– pH: 6.0-8.0

– water temperature: 21-23 degrees.

In addition, it is very important to regularly replace part of the water, but not much. For spawning, several males are taken for 6-7 females, only they should be kept separately for about two weeks. Females spawn will be a couple of days and only sweep up to 300 eggs, which literally in two or three days will turn into fry.

Parents take care of their fry and do not eat. In order to accelerate the growth of fry, it is better for manufacturers to plant out and let the small things feed themselves. First you need to give the fry live dust, ciliates and finely chopped bloodworm.

In a few weeks, small cyclops and daphnia will be used. A little later, small things are sorted by size and seated.
