The color of the fish is bright. The most common is red. Sizes range from 20 cm to 1 meter in length.

Small individuals live in aquariums, and larger ones inhabit artificial ponds. There are also blue, yellow and white varieties.

Depending on the color, there are about 60 varieties of koi.

Life expectancy of an individual with the right content is from 20 to 30 years. There are exceptional cases when some individuals lived in ornamental ponds for more than 200 years.

Koi at home eats varied. It is possible to teach him to a certain type of food. To determine the required amount of food, weigh koi fish and give it 3–4% by weight daily.

Such a calculation will not overfeed. It is believed that it is better to give less to eliminate digestive problems.

Problems are usually associated with the fact that the digestive canal of an individual is represented by a long tube. When overeating food turns into a lump and can cause the death of the fish.

There are several feeding features that are recommended to be observed:

  • Give food 2 or 3 times a day in small portions.
  • Ensure that the fish consume the entire volume in 5-7 minutes.
  • Food residues should not be a source of water pollution in a pond or aquarium, as this will lead to fish diseases.
  • It is recommended to give live food in the form of moths and larvae, but in the absence of such it is allowed to replace it with vegetables, boiled eggs, fruits and even shrimps.

For people who do not have a lot of free time, such pets are not suitable. They can not be given food in the amount of the daily norm and leave. Products must be supplied regularly and in small portions.

This species belongs to unpretentious individuals. and does not require increased attention, except for the moments of feeding. For water, they are also unpretentious.

The only condition will be its purity and the absence of harmful impurities.

The content in the decorative pond is considered the most favorable. It is necessary for the development and growth of fish. In an aquarium setting, koi will not gain weight.

That is why many lovers are building a homemade decorative pond for keeping individuals in the garden.

In aquarium conditions usually contain small representatives, which do not require much space. But even for small fish, the volume of the aquarium should not be less than 500 liters.

Koi prefer space and in the crammed die quickly.

Koi content in an ornamental pond is considered the most favorable.

There are several nuances concerning water:

  • Water in the aquarium should be replaced daily in the amount of 30% of the total. This important condition should be observed for the fish to live for a long time.
  • One more thing will be the uninterrupted filtration and the provision of sufficient oxygen in the aquarium. In large decorative ponds, external filters are usually used that do an excellent job.
  • To the water temperature, koi are also unpretentious and perfectly survive at + 15−30 degrees. At the same time, the processes of their vital activity are not disturbed.
  • When the temperature drops to +10 degrees, koi begin to slow down the vital processes and prepare for hibernation.

The bottom of the aquarium should be littered with small sand. If there are various decorations, they should be attached well and the places of attachment should also be masked with sand.

With a strong desire, it is allowed to put a few pots of plants in 10−15 cm from the bottom. You should not be zealous, because the fish loves the space necessary for swimming.

Some lovers completely deprive the aquarium with koi carps and decorations and plants, which does not affect them at all.

The character of koi is peaceful and they easily get along with other representatives of carp, catfish and varieties of aquarium fish. However, during the breeding season, males may become aggressive. They not only cause harm to females, but can also use smaller representatives of the aquarium as food.

However, this behavior is typical only during the breeding season, and the rest of the time the brocade carp is calm and peaceful.

Owners of this species claim that their pets are developed intellectually and understand the words of the owner. It really can be considered true.

This is because the fish develops a reflex. If, during feeding, a person makes certain sounds, speaks to fish or sings to them, they remember it and begin to be active at the sound of his voice.

Breeding of this species is practiced in specialized places and conditions suitable for this. Some difficulty is created by the fact that it is almost impossible to determine the sex of a fish before the onset of puberty.

The advantage of fish is the lack of need to create any conditions for spawning. Its time usually falls in the spring – summer, when the water temperature in the pond rises.

Females and males are considered mature when they reach 22−24 cm in length.

The advantage of fish is the lack of need to create any conditions for spawning.

In order to stimulate spawning, it is allowed to slightly increase the daily rate of food and feed mainly with live food. Many professionals who specialize in koi breeding prefer to select a pair of the most active fish and place them in a separate pond or aquarium.

This will help produce healthy offspring.

Given the ability of the male to eat fry, it should be placed after laying the calf in a separate pond after the female is laid. The amount of water does not matter at first, but a constant supply of oxygen is essential for the normal development of the fry. As a rule, the time from laying eggs to hatching fry is 4-7 days.

After that, they are attached to the walls of the reservoir for 3 days.

Carp koi – amazingly beautiful and unpretentious fish.

This period they need to adapt. After 4 days, they begin to swim. It will take several more days until the fry swim freely.

Only then should they begin to feed.

Carp koi – amazingly beautiful and unpretentious fish, which will decorate a decorative pond and a home aquarium will become a true friend for lovers of such pets.
