Common Goldfish

maintenance, care, compatibility

Goldfish (lat. Carassius auratus) is a freshwater fish of the carp family, of the Beaverguda order, of the Karas family.

For the first time, goldfish were domesticated more than 1500 years ago in China. They are direct descendants of gold crucians.

Nowadays, many types of goldfish are popular pets that have many morphological characteristics.

More than 1000 years ago, a goldfish was a dweller of ponds and small decorative ponds, later it began to be kept in small clay tanks, which became the prototypes of modern aquariums. In the XIV century, the Chinese ruler ordered to organize the production of special containers for the maintenance of “silver” crucians.

The vessels were made of porcelain and ceramics, decorated with ornaments, and enjoyed great popularity among the nobility.


Although the cups were not transparent, and the goldfish could not watch the world through them, however, people began to pour sand onto the bottom of the cups and add plants to the container. In such a vessel usually contain one or more fish.

In the modern aquarium, everything is different – the tanks are transparent, equipped with instruments and decorations, so all types of goldfish can feel as comfortable as possible.

These are the most popular fish for beginners, which are distinguished by endurance and unpretentiousness in the content. However, almost all goldfish are cool-loving, they prefer to live in water at a temperature not higher than 24-25 ° C.

Some tanks require aeration of water, and, of course, mandatory filtration and siphon of the soil. Goldfish are untidy: they constantly dig up the ground, eat a lot of food, and leave behind a lot of excrement. At least one individual needs at least 50 liters of aquarium water.

It is recommended to settle with non-aggressive, omnivorous fish that will not bite off the fins, and will be able to live in cool water.

See how to contain goldfish.

As aquarium decorations, you can use plants, shelters and snags. The entire decor is required to process, it should not be scratches, sharp corners.

It is not recommended to install sinks, stone sculptures, snags with pointed branches in the tank. It is advisable to plant hard-leaved and soft-leaved plants that a goldfish can eat (duckweed, wolfia, richchia).

Some goldfish are contained in almost empty reservoirs due to the high probability of injury (telescopes, tails).

All goldfish are omnivorous hydrobionts. In addition to plants, they eat live, frozen and branded feed. With pleasure they eat food “for people” – boiled cereals, lettuce, spinach, dandelion, nettle.

From animal food they can be given a chimney, daphnia, artemia, bloodworm, cortex, sliced ​​meat of shrimp, earthworms. Goldfish are highly prone to overeating, so feed should be given metered – 2 times a day in small portions.

Adults prefer plant food, and young animals prefer protein foods.

The goldfish becomes mature at the age of 1 year, but if you plan to cross breeds, it is better to wait until it reaches a more mature age (4-5 years). In the wild, Karasiki spawns in the middle of spring. The readiness for spawning is determined by external signs: in the area of ​​gill covers hillocks appear of a light shade, the pectoral fins are characterized by small notches.

These features of appearance are peculiar to both males and females. The abdomen of females is rounded and increases in size.

The male begins to pursue the female, drives her into shallow water with dense vegetation. Therefore, simulating reproduction in the natural environment, the water level in the spawning tank is reduced to 15-20 cm. For a spawning aquarium, a capacity of 50-100 liters with aeration and good lighting is suitable.

In spawning you need to put a separator grid so that manufacturers do not eat fallen eggs. Planting of dense vegetation is allowed.

Spawning lasts 2-5 hours, after the process, the male and the female need to be deposited.

Look at the spawning goldfish.

In one year, goldfish can breed 2-3 times. Larvae of fry appear 2-6 days after fertilization, which depends on the temperature of the aquatic environment. The lighting speeds up the ripening process, and the shade stops.

In the first days of life, the larvae are almost stationary, fixed on aquatic plants, and eat up the contents of the yolk sac. After its exhaustion, the fry begin to swim independently in search of food.

Starter feed – Artemia nauplii, live dust, rotifers, special fry food. When the fry grow up, they need to be sorted by size, and settled in different tanks.

Tellingly, the descendants of beautiful parents may turn out to be plain and vice versa.

There are two groups of rocks:

Long-bodied. The shape of the body of these fish is similar to their ancestor – wild punishment. They are distinguished by greater mobility, stamina and longevity (40-year-old longevity stories are known!).

In addition, they need less oxygen. Representatives of this group are the comet, wakin and the usual goldfish.

Short-bodied. They differ in a variety of shapes, but what unites them is that the body is compressed from head to tail.

Such experiments did not go unnoticed for the health of these fish. They are sick more often, adapt worse, live less (no more than 10-15 years), more demanding of conditions. In particular, they need a larger body of water and a high content of oxygen in the water.

This group is represented by a telescope, a pearl, a lionhead, and others.

There are many breeds, and the same goldfish can have different names in the literature, since breeders of different countries called them and called them.

Its second name is gold carp. Was obtained by breeding from a wild goldfish.

Similar to him in body shape and fins, different colors (golden-red fish).

She needs a reservoir with an abundance of plants and space for swimming. It should be kept in a species aquarium or only with peaceful neighbors.

Food is recommended a varied, balanced, no frills: animal and vegetable food in the form of tablets, granules, sticks, dry, live or frozen. Under good conditions, it can live from 10 to 30 years.

The variety of aquarium fish sometimes affects. And given the fact that one species of fish has its own varieties – the aquarium world becomes just gigantic.

Sometimes it is even difficult for an experienced aquarist to tell what kind of fish it is. Hopefully, the following selection of GOLDEN FISH SPECIES will help you figure out who is swimming in your tank.

Carassius auratus

Order, family: carp.

Comfortable water temperature: 18-23 ° C.

Ph: 5-20.

Aggressiveness: 5% are not aggressive, but they can bite each other.

Compatibility: with all peaceful and non aggressive fish.

DESCRIPTION:

Golden, or Chinese, crucian carp in nature lives in Korea, China and Japan.

The goldfish was bred in China more than 1,500 years ago, where it was bred in ponds and garden ponds on the estates of nobles and wealthy people. For the first time, a goldfish was imported to Russia in the middle of the 18th century.

Currently, there are many varieties of goldfish.

The color of the body and fins is red-golden, the back is darker than the abdomen. Other types of color: pale pink, red, white, black, black and blue, yellow, dark bronze, fiery red.

A goldfish has an elongated body, slightly compressed from the sides. Males can be distinguished from females only during the spawning period, when the female’s belly is rounded, and the males on the pectoral fins and gills develop a white “rash”.

For the maintenance of goldfish, an aquarium with a capacity of at least 50 liters per specimen is best suited.. Short-bodied goldfish (voiletails, telescopes) require more water than long-bodied (simple goldfish, comet, shubunkin), with the same body length.

With an increase in the volume of the aquarium, the planting density can be slightly increased. In particular, in the volume of 100 l you can settle two goldfish (you can have three, but in this case it will be necessary to organize a powerful filtration and make frequent water changes). 3-4 individuals can be planted in 150 l, 5-6 in 200 l, 6-8 in 250 l, etc.

This recommendation is relevant if we are talking about fish of at least 5-7 cm in size without taking into account the length of the tail fin.

A special feature of the goldfish is that it loves to rummage in the ground. As the soil is better to use coarse sand or pebbles, which are not so easily scattered fish.

The aquarium itself should be spacious and species, with large-leaved plants. Therefore, in an aquarium with goldfish, it is better to plant plants with hard leaves and a good root system.

In the general aquarium, goldfish can be kept along with calm fish. The necessary conditions for the aquarium are natural light, filtration and aeration.

Water characteristics: temperature can vary from 18 to 30 ° C. The optimum should be considered in the spring-summer period 18 – 23 ° С, in the winter – 15 – 18 ° С.

The fish tolerate a salinity of 12-15%. If you feel unwell fish in the water, you can add salt, 5-7 g / l.

It is advisable to regularly replace part of the volume of water.

Goldfish are unpretentious regarding feed. They eat quite a lot and willingly, so remember that it is better to underfeed the fish than to overfeed them. The amount of food given daily should not exceed 3% of the weight of the fish.

Adult fish are fed twice a day – early in the morning and in the evening.

Feed is given as much as they can eat in ten to twenty minutes, and the remnants of uneaten food should be removed. It is necessary to include both live, and vegetable food in their diet.

Adult fish that receive proper nutrition can endure a week-long hunger strike without harm. It must be remembered that when fed with dry food, they should be given in small portions several times a day, because when they get into a wet environment, in the fish’s esophagus, it swells up, increases significantly in size and can cause constipation and disruption of the normal functioning of the digestive organs of the fish, the consequence of which could be the death of the fish. To do this, you can first hold the dry food for some time (10 seconds – flakes, 20-30 seconds – granules) in water and only then give them to the fish.

When using specialized feeds you can improve the color of the fish (yellow, orange and red).

Long-bodied goldfish durable, under good conditions, they can live up to 30 – 35 years, short ones – up to 15 years.
