I just bought a few little goldfish, how do I raise them?

1. Feeding: Feed nutritious animal feed and white sesame seeds. Animal feed such as daphnia, earthworms, mealworms, green worms, skin worms, etc.

The main feeds are earthworms and white sesame seeds. Both red and black earthworms can be fed. It can be fed with raw white sesame seeds.

White sesame seeds are readily available. Goldfish are very fond of eating, easy to digest, and do not easily pollute the water. Do not feed low-quality goldfish feed that you have bought.

Because this feed has too much starch, poor nutrition, is not easy to digest, and the water quality is easy to pollute, goldfish eat malnutrition, goldfish growth is relatively slow, and it is easy to get sick. As long as the goldfish eats easy-to-digest food, it will not die.

When to feed, generally once a day in the morning and afternoon, it is not advisable to feed more, until it is eaten. Otherwise, it will pollute the water quality.

2. Light: It is best to put the fish tank in the sun.

Shoot for 1-2 hours in place. In this way, the sun's ultraviolet rays are used for sterilization. It plays a role in disease prevention. This reduces the number of diseases. Try to prevent fish diseases as the main thing, supplemented by medication. At the same time, due to photosynthesis, the color of the fish body is also relatively bright and beautiful.

3. Water change: Frequent water change can increase the dissolved oxygen in the water. When changing the water, you can only change one-third to one-quarter, and you can't change a lot at once, and the fish are not adaptable.

It is important to keep the water in the aquarium clear. Fish with sufficient dissolved oxygen in the water can grow and grow quickly. Otherwise, it stops growing or even dies.

When to change the water, there is no conclusive conclusion, it can be determined according to the water quality, the water quality is turbid, otherwise it is less changed.

4. Stocking density:

Due to the small size of the domestic rectangular aquarium, it is important not to raise more, and it is better to raise less than more. For example, in a container with a length of 40 cm, a width of 25 cm, and a height of 30 cm, small goldfish 5 to 7 cm long can be raised6

8 tails. For example, a circular glass tank with a diameter of 26 cm and a height of 13 cm can raise 4 6 small goldfish of 4 6 cm. Adult fish with a body length of more than 8 cm should not be raised in a small glass tank, but need to be raised in a large glass tank or a ceramic tank, and equipped with a small aerator for backup to prevent hypoxia.

These stocking densities are only reference numbers, and they also depend on the water temperature, the strength of the fish and the quality of the water. Generally speaking, the fish are large and have a small number of feeds; More in winter and less in summer; When the water temperature is low, you can raise more, and when the water temperature is high, you can raise less. Domesticated goldfish, if you master the above points, you will be able to keep the goldfish healthy and lively, colorful, swim in the water, loved, so that you never get tired of watching, and have endless fun.

The bait feeding adheres to the principle of three determinations, qualitative: high protein content, fresh and clean; Quantitative: Pay attention to the time when the goldfish in the pool are eaten each time, generally within 20-30 minutes; Timing:

In the summer, around 7 a.m. and 3 p.m., in the winter, the fish swim less, so they can be fed around noon.

It should be noted that every feeding must be fed at one time, and duckweed or a small amount of pellet feed should be appropriately fed according to the appetite of the fish;

Synthetic pellet feed is mainly used in yard farming, which is a very good auxiliary bait and the best substitute for natural bait shortage.

After buying the goldfish home, don't rush into the tank, put the plastic bag containing the fish into the fish tank for 10 to 20 minutes and then open it, let the water in the tank pour into the bag several times, and gradually mix with the original water in the bag, so that the goldfish gradually adapt to the water temperature and water quality. If there is a light, turn it off. In the dark, the fish are quieter and less easily frightened.

When buying fish, you should pay attention to the water temperature of the aquarium store and the water temperature of your fish tank, and the deviation should not be too large, generally within 4 is allowed. Fresh water must be stored for a day or two. The purpose is to remove some of the chlorine from the water and also to bring the temperature of the new and old water closer.

Feeding principles:1The number of feedings per day only needs 1-2 times, and the amount of each feeding should be eaten within 1-2 hours. The weather and water quality are normal, and the feeding amount can be appropriately increased for the fish with strong vitality.

2.Feeding time Spring and summer should be early, generally around 6-7 o'clock in the morning, when the sun begins to dry and fish ponds (tanks) to feed. The feeding time in late autumn and winter can be a little later, generally around 7-8 o'clock, and even delayed until around 10 o'clock in the cold winter season.

However, do not feed in large quantities in the evening. Even if the fish are clearly feeding, it is better to feed in small quantities around 3 p.m. After November, the water temperature drops significantly, and the appetite of goldfish tends to decrease, and it is not suitable to feed in the evening.

Goldfish and crucian carp belong taxonomically to the same species (carassius auratus).

Originating in China, the goldfish is also known as the "golden crucian carp", which is similar to the carp (cyprinus carpio) but it has no whiskers and is an ornamental fish that evolved from the crucian carp. There are many varieties of goldfish, the color is red, orange, purple, blue, ink, silver white, five flowers, etc., and it is divided into four strains: literary species, grass species, dragon species, and egg species.

In the history of human civilization, Chinese goldfish has accompanied human beings for more than ten centuries and is the earliest species in the history of ornamental fish in the world. Goldfish is easy to raise, it has a strange posture, brilliant colors, generally golden yellow, and beautiful shape. Goldfish can beautify the environment, is very popular with people, and is an ornamental fish with Chinese characteristics.

Goldfish in China are mainly developed on crucian carp. After the introduction of colored carp to Japan, it was highly valued.

With the efforts of generations of goldfish farmers, Chinese goldfish still interpret the legend of beauty between movement and stillness to the world. There is another saying about goldfish in our country: when you come to the New Year, you can buy two goldfish at home, which means that you will be full of gold and jade in the coming year, and there will be more than enough every year.

Resources.

1.If you want to have a goldfish, you need to prepare first, that is, use a basin or bucket to dry the water two days in advance, if you can't bask in the sun, you must also put it for two days in advance, because this can allow the chlorine used for disinfection in the tap water to escape from the water.

2.Secondly, the number of goldfish should be determined by the fish tank, the fish tank can put two more fish, and the fish tank is small, especially the small fish tank without oxygen injection tube. Otherwise, not long after the goldfish are put in the tank, you will send out that all the fish are breathing on the surface of the water, and if you don't find such an obvious problem, just think that they are playing on the surface, you are very wrong, and the next day, you will find out that several more fish have died honorably.

3.If there are too many fish, the few dissolved oxygen in the water will be quickly consumed by the fish, and the dissolved oxygen at the beginning of the contact between the water surface and the air is enough to supply the fish with breathing, but soon the fish will die of lack of oxygen.

4.If you know the first two, you may not be so clear about this one, many people say that fish can't be fed too much, and if you feed too much, the fish will die. In fact, the fish will not die, there are students who study animals have done experiments, to feed different amounts of fish food, has not changed the water, until the fish died, after the dissection found that even if there is a lot of fish food left in the fish tank has not been eaten, the fish with a very bulging belly, there is still an empty space in her intestines, which is enough to show that the fish is not dead.

The main reason why fish die is because of too much fish food, and when the fish can't eat it all, the oxygen in the water will be consumed during the dissolution of fish food, and the fish will die of lack of nutrients. Therefore, it is best to feed the fish in moderation every time to ensure that the fish is eaten within 2 to 3 minutes. The most important thing is to change the water of the goldfish regularly, and change the water that has been sunburned to ensure that the oxygen supply is sufficient and the fish tank is clean.
