Goldfish: description, size, distribution
The ancestor of the fish is pond carp. The first aquarium goldfish appeared about one hundred and fifty thousand years ago. It was brought out by Chinese breeders.
Outwardly, the fish look the same as their ancestors: single anal and caudal fins, an elongated body, straightened paired pectoral and ventral fins. Individuals may have a different color of the body and fins.
You can keep goldfish not only in aquariums, but also in ponds. pond fish grows up to thirty centimeters, in aquariums – up to fifteen. Being a breeding form, they do not live in the natural environment.
Fish can breed already in the second year of life. But in order to get good offspring, it is better to wait for them to reach the age of three or four. Goldfish can breed several times a year, and spring is a more favorable period for this.

Keeping goldfish in an aquarium
No problem keeping goldfish subject to a number of conditions:
- Setting up an aquarium.
- Settling the aquarium with fish.
- Proper feeding.
- Regular maintenance of the aquarium.
- Disease prevention.
Choosing and arranging an aquarium
First of all, it should be noted that for goldfish, the aquarium must be with a capacity of at least one hundred liters.
When purchasing soil, you need to pay attention to its fraction. Goldfish are very fond of sorting out pebbles and fine soil can get stuck in their mouths. Therefore, it is recommended to buy a fraction of more than five millimeters.
Aquarium equipment:
- Heater. Although goldfish are considered cold-water, they do not feel very comfortable at temperatures around twenty degrees. And such individuals as lionheads, telescopes and ranches are more thermophilic. You can keep the temperature in the aquarium at a level of twenty-two to twenty-five degrees. Here you should choose according to the well-being of pets. It is also necessary to know that fish kept at elevated temperatures age faster.
- Internal filter. In connection with their physiology, goldfish are characterized by high mud formation. In addition, they love to dig in the ground. Therefore, for mechanical cleaning in an aquarium, a good filter is simply necessary, which will need to be washed regularly under running water.
- Compressor in an aquarium it will be useful, even if the filter, in aeration mode, does its job. Goldfish need a fairly high oxygen content in the water.
- Siphon needed for regular cleaning of the soil.
In addition to the basic equipment, plants should be planted in the aquarium. This will help fight algae, have a positive effect on the ecological situation, and simply be pleasing to the eye. Goldfish are happy to eat almost all aquarium plants, while receiving an additional source of vitamins. So that the “flowering garden” of the aquarium does not look gnawed, you can plant a certain amount of hard and large-leaved plants to the “tasty” plants, which the fish will not touch. For example, lemongrass, anibus, cryptocoryne and many others.
What to feed goldfish
The diet of goldfish may include: feed, earthworms, white bread, bloodworms, semolina and oatmeal, seafood, lettuce, minced meat, nettle, hornwort, duckweed, richcia.
Dry food It takes a few minutes to soak in aquarium water. When feeding only dry food, the digestive system can become inflamed in fish.
Do not overfeed goldfish. On the day, the weight of food should be no more than three percent of the weight of the fish. Overfeeding leads to infertility, obesity, inflammation of the gastrointestinal tract.
Fish should be fed twice a day, leaving food for no more than fifteen minutes. Excess feed is removed by a siphon.
Disease Prevention
To prevent your pets from getting sick, you need to follow some content rules:
- monitor the purity of water;
- do not overpopulate the aquarium;
- observe the feeding regimen and the correct diet;
- Avoid hostile neighbors.
Breeding and spawning
Goldfish are bred in containers ranging from twenty-five to thirty liters. The container is filled with sandy soil, water, the temperature of which should be about twenty-five degrees and small-leaved plants. To stimulate spawning, it is recommended to heat the water five to ten degrees more than the original. The spawning area should have powerful insulation and bright lighting.
Before planting fish for spawning, it is necessary to have heterosexual individuals two or three weeks to hold separately. After that, one female and two or three males are launched into the aquarium. Males start chasing the female at high speed, which contributes to the distribution of eggs throughout the aquarium (mainly on plants). The mark can last from two to five hours. One female lays from two to three thousand eggs. After spawning, the parents are immediately removed.
The incubation period in spawning lasts four days. During this time, whitened and dead eggs should be removed, which can become covered with a fungus and infect the living.
Fry emerging from eggs almost immediately begin to swim. They are developing quite quickly. Water for keeping fry should be at least twenty-four degrees. The fry are fed with ciliates, rotifers.
In a good aquarium with enough water, with proper care, goldfish will delight the owner with their beauty for a long time.
