Koi carps in aquarium

maintenance, care, compatibility


Do carp koi it is impossible to determine gender before they reach puberty. Usually they enter spawning age when they reach a length of 23 cm.

But sometimes even adults are difficult to determine gender. The main signs of gender difference are:
-males are more sharp and visually large (relative to the body) pectoral fins;
-in females, the body is “heavier”, which is associated with a greater need for nutrients (for normal egg production);
-in the mating season, the males on the gill covers appear tubercles (in appearance as a semolina);
-anal holes males and females have differences.

If carps live in a pond, most likely they will spawn at the end of spring or early summer (that is, when the temperature rises), of course, provided that they are mature, healthy and fed enough. The temperature ideal for spawning is 20? C.

If in the pond a lot koi, then you can watch the mass spawning. Such spawning leads to the birth of healthy offspring, but many aquarists avoid it, because these fry usually have a much paler color than their parents.

Professional breeders select a certain pair of parents and put them in a separate pond. It will take 2-3 males and one female.

If there is no special pond for spawning carps, and you don’t want to dig it up, then a mini-pool for children will fit perfectly. To increase the chances of spawning more frequent water changes are made.

Also in the koi menu you can add more live food. Koi carp lay their caviar.

For adults, these carp are characterized by eating not only caviar, but also fry. Therefore, if you need a great productivity of spawning, then after spawning, the eggs should be placed in a separate pond or aquarium.

Malki need a large amount of oxygen, otherwise they will not survive.

After 3-7 days (depending on temperature) fry begin to hatch. You will learn about this by the specific brilliance of the eggs.

As soon as they appear, they are immediately attached to the edges of the pond. The fry have a special sticky pad on their heads, which allows them to attach to any surface and hang for 2-3 days there.

After these days, koi fry swim freely, only periodically swimming up to the surface for air. Air enters the swim bladder, and koi can safely swim in the water for a while.

Until the fry begin to swim freely (i.e., until they peel off the surface), they do not need to be fed.



Carp koi: meaning, description, features. Although carp koi and called the Japanese, in fact, the birthplace of “living jewels” is China.

Extraordinarily beautiful fish came to Japan about a thousand years ago and from there spread throughout the world. Currently, carp koi, whose value cannot be overestimated, plays a significant role in the decorative design of ponds.

Koi – a fairly large representative of freshwater fish, reaching a length of one meter. No less long is the life of the carp.

On average, koi live 25 – 35 years. But in good conditions, with constant competent care, carp can live for at least a hundred years.

Rules for feeding koi carps:

  • fish should eat food for 5-10 minutes,
  • the feed must not pollute the water
  • better not to feed than to overfeed,
  • often (2-3 times a day) to feed in small portions,
  • fish should receive daily feed in the amount of 3% of its own weight.

It is useless to give carp koi a large portion of food once a day, since they cannot digest everything at once – instead of the stomach, the long intestinal tract.

Initial feed for fry: artemia, daphnia, ciliate, wheat yeast, spirulina. Live food is recommended, but if there is none, then boiled egg yolk will do.

After a week, the fry can be fed with crushed granules. When they reach 1.5 cm in length, they can be given small granules, which should be increased in size as the fish grow.


Koi brocade carps reach the big sizes and gain the weight corresponding to them only in the conditions of an open pond. For normal development, they need space and relatively clean water.

In terms of the required volume and space for the maintenance of these exotic fish, there is a formula:

for every centimeter of the size of an individual, 5 liters of water are needed.

You do not need to be a great mathematician to determine the volume of the tank for a 70-centimeter carp. This is the minimum volume in which a large individual is practically nowhere to turn.

Therefore, brocade carp is better to keep in a capacity of 500 liters and more.

In addition, in the aquarium conditions, the Japanese, as a rule, do not grow to large sizes, their length usually does not exceed 30-40 cm maximum. Such an impact on the development of conditions have a content in a small volume.

Koi carps: multicolored, like a rainbow, delight your beauty with your beauty!

Many millions of words have been written about these wonderful fish of the most varied coloring and kilograms of kilobytes of digital photos have been taken. The carp koi is beautiful in ponds and aquariums.

In pond equivalent, there is no need to talk about the special transparency of the water, although there they are also trying to keep an eye on it. But moving to an aquarium will require, of course, achieving maximum transparency. And indeed, let us imagine for a moment: a handsome carp koi in an aquarium where the water in its green shade resembles a pond in which Duremar was catching his favorite leeches!

Therefore, we will not discount the need to purchase a good equipment for a large aquarium.
Let’s start with filtering, and quite powerful. At a minimum – a couple of FluvalFX-5 plus every week we replace at least a third of the fresh water.

Rinse this technique only when the filters are really dirty. And for this, the filter material should not be overly fine-grained and fine-grained.

In this regard, the 2250th, 2260th and 2080th models of Eheim are good.
The best breeding option for carp koi would be the duct. Here it is better, of course, to weigh everything in advance.

And if you don’t match the duct with the water supply, then you can limit yourself to a storage tank of liters of commercials for … a few hundred.

UV sterilizers are a useful and welcome plus. Especially brands Tetra and JBL.

Power – watts 11-18. And not Chinese options, although perhaps in a few years they will start making quality products.
The same advantage is considered air aeration. Of course, unpretentious koi carps can be maintained without it, but a constant champing in the process of swallowing air from the surface of the water is unlikely to help preserve the harmony in the apartment!
It is hardly worth stocking up with a heater unless the breeding of koi carps begins with their transfer from the street to the house in winter. It should be remembered that with this fish emit more mucus, and this is a premature clogging of filters.
You should also pay attention to the need for a large amount of light in the lighting of the aquarium. Preference is given to lamps SylvaniaGro-lux. Adapted koi carp best in “adolescence”.

Feed this unpretentious fish should be granules, in which there should be spirulina and axtaxanthin, as well as fruits and vegetables. To feed carp koi in an aquarium loves, like a person, 3-4 times during the day, or even more!

Japanese koi carps are large in size, the five-year-old individual reaches 80 cm and more than 15 kg. Koi are evaluated on some external parameters.

The carp gets a high mark if it has proportional shapes and sizes of all parts of the body, and also has a balanced color pattern.

The color of carps varies depending on their subspecies. The main shades are white, yellow, blue, cream, red, black. The brightness of the color of fish is directly affected by koi carp feeding, water quality and sunlight.

In a spacious aquarium, koi will fully reveal the fullness of their color.

Koi carps have good health, unpretentious care, calm and hardy. Koi are able to distinguish colors, smells and tastes, susceptible to training. They can sleep on their side and prefer one partner.

Carp live for a long time, in an aquarium up to 30 years, but under natural conditions, the average age of koi reaches 50 years.

Against the background of koi, other fish look inconspicuous, but there are some species suitable for them in the neighbors. The carps transferred from the pond to the aquarium initially behave with caution, hiding and frightening. Juveniles adapt faster and easier.

Adaptation can be accelerated by hoisting comets or shubunkins to them.

Koi carps are well combined with such neighbors as gorchak, plebostomus, trout, catfish, mollies, goldfish, gudgeons, barley, sunny bass. Small fish such as danios and cardinals will eat carps over time.

Koi carps are not just a decoration of an aquarium or pond, the owner will seriously become attached and make friends with these pets, who have amazing intelligence and interesting habits. Longevity, simple maintenance at home and their breeding will allow to enjoy the koi society for a very long time.

Content of Japanese carp in ornamental ponds

If you provide good filtration and aeration of water, the Japanese carp can be kept in the home aquarium large enough.

Carps, like all living things, grow and change with age. Angular impetuous adolescents are not as beautiful and interesting as respectable adults.

But for keeping at least six-year-old carps, the volume of the aquarium should reach about a thousand liters, and with the prospect of growth of its inhabitants – two thousand.

Carps themselves do not need special water clarity, but for observers there is no need for interference, therefore powerful filtration is needed. You can do without aeration, but the squishing sounds that carps emit, gulping air on the surface, do not contribute to peace.

Aquarium with Japanese carp should be well lit so that the fish look bright and contrast.

It is best to feed carps in an aquarium with dry granulated food, which enhances the color of the fish and does not affect the quality of the water. You can supplement the diet with finely chopped fruits and vegetables, the remnants of which should be removed from the aquarium after eating.

Since beautiful Japanese carps are an ornament not only to the aquarium, but also to the room itself as a whole, the choice of soil depends on the color of the fish and on the interior. The main thing is that the amount of decor in the water was minimal.

Japanese carps were bred initially for observation from above. But how wonderful a Japanese carp looks in an aquarium!

The photo shows it quite clearly.

Feeding Japanese carp is best granulated feed, depending on water temperature and fish activity, from two to six times a day. In winter, carp eat very little.

Koi carps respond well to any food. It can be beans, and cabbage, and watermelon. Since ornamental fish are intended by nature to be admired by them, the food for them is selected not only for the balance of nutrients, but also for buoyancy.

Special pleasure gives owners with hand-feeding.

If under the surface of the water to establish a decorative light, then the night insects flying to its light and fallen into the pond will be a natural food for fish.

When feeding fish, no matter how much pleasure this process delivers, it is necessary to observe an unshakable rule: it is better to underfeed than overfeed, especially with artificial feed.

The back, chest, thigh, or shoulder are the places to which the tattoo is applied, where the Japanese carp is depicted. The value of this image is good luck.

It is believed that the value of luck, which brings the image of Japanese carp koi, is proportional to the size of the tattoo.

The color of the fish in the picture is also important: black – overcoming pain and strong feelings that raised a person to new heights; red – love, strength and energy; blue is courage.

Unshakable courage, composure in battle, fearlessness before any fate – these qualities of a samurai warrior are embodied in the Japanese carp (tattoo). The value of this symbol is enhanced by the image of water, which symbolizes the flow of life. If in the figure a carp is swimming against the waves, then this means that a person is ready to overcome all difficulties in his life in order to achieve his goal.

A strong character, a desire to survive against all odds will help such a person go against the opinions of others.

If a carp swims in the image with the flow, then it symbolizes peace after reaching the cherished goal, awareness of the meaning of life, confidence in swimming through the waves of life.

If the tattoo depicts a pair of fish, this means a happy union, the harmony of relations between a man and a woman. In such a tattoo, the color scheme is important: the carp is black – the father, the bright red is the mother, the white or blue is the son, and the pink is the daughter.

As you can see, a tattoo (Japanese carp) can have a different meaning ..

Another philosophical meaning is the dignity of the Japanese carp: it can live for centuries. For more than two hundred years has lived passed from hand to hand fish – koi carp named Hanako.
