Goldfish become very cautious after changing from a small tank to a large tank, and are afraid to me

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, and is not easy to digest, the water quality is easy to pollute, and the goldfish are malnourished after eating.

Goldfish grow more slowly and are more susceptible to disease. 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 place the fish tank in a place where there is sunlight for 1-2 hours. 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 must not be raised more, and less should not be more. For example, in a container with a length of 40 cm, a width of 25 cm, and a height of 30 cm, 6 8 small goldfish with a length of 5 7 cm can be raised.

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. I will definitely be able to raise it, I wish you success.

In the past few days, it is recommended that you use a cardboard box to wrap the noodles that can be seen in the entire fish tank, shade them for a few days, and then leave a few small seams to observe, try not to make noise during this time, and do not make too much noise, so that it will be basically normal after a week! Or you can feed some bloodworms or shithorns (mosquito larvae, there are flowers at home and there are moving insects in the place where the water is standing at the bottom of the pot, then the syringe is drawn out and fed)!Fish are excited to see something alive!!

You can also buy a few more fish to put in, which is also a good choice!

Hope mine can help you!

<>1. Because goldfish are very sensitive, when they get oxygen, they are frightened, and they have many benefits for the fish, increasing the amount of dissolved oxygen in the water, having a strong appetite, good vitality, not easy to get sick, and it is also good for cultivating nitrifying bacteria.

There are benefits; 2. Because the lateral line of the goldfish is very sensitive, as long as the water trembles slightly, the goldfish can make an instinctive response;

3. Because of oxygen and red blood cells in the blood.

combined, so that the goldfish is energetic.

The reason why the goldfish in the fish tank don't grow big:

1. The fish tank is too small and there is no space, and it is difficult for the fish to grow up.

2. When buying fish, I bought an old fish, which has passed the age of growing up and cannot grow up again.

3. Only feed ordinary fish feed, general feed will cause malnutrition, so it will not grow much.

4. Goldfish are not large goldfish in the first place, they may be small species.

Additional instructions: 1. Place the glass cylinder in a ventilated and sunny place near the window. It is necessary to pay attention to the stocking density, according to the size of the container, reasonable arrangement, rather less raising, not more raising.

Because the indoor air circulation is not large, the water is easy to be turbid, which is easy to cause goldfish to die due to lack of oxygen. If you have an air pump, you can raise more, and if you find that the goldfish has a floating head, you need to open the air pump to oxygenate, especially at night, you need to be oxygenated.

2. The bait used in fish farming is the most ideal for live fish and insects, and the water quality is not easy to be damaged. Now there are live fish and insects on the market**, but it is also troublesome to buy them every day. For the dried fish and insects sold in the market, you should choose relatively fresh and loose particles to feed the fish, and do not buy old and moldy dried fish and insects to feed.

Artificial pellet feed is simple to use full price feed with complete nutrients, and it is sold in the market.

3. In order to maintain the purity of the water quality, the amount of bait should be strictly fixed and quantified, usually 1 to 2 times a day is appropriate, and the amount of bait should be eaten within half an hour, and the bait should not be fed too much.

The reason why there are fewer and fewer small goldfish in the fish tank is that the more difficult it is to control the water quality in the fish tank, it is easy to cause the death of the fish in the fish tank.

Goldfish belong to the same species as crucian carp taxonomically, and compared with crucian carp, goldfish have huge variation in external morphology, but in general, the whole fish body can be divided into three parts: head, trunk, and tail. The anterior end of the head is the mouth, and the posterior part has the nose, eyes, and gill cover. Some breeds have sarcomas at the upper end of the head.

Some varieties have pompoms above their noses, some have bulging eyes, are facing upwards or have blisters, and some have branchls that leak out. The body of the goldfish is covered with scales, mainly including normal scales, transparent scales and pearl scales.

It has lateral lines on its sides, and the number of lateral line scales, lateral line scales, and lateral line scales varies among different species of goldfish. A typical goldfish torso has pectoral fins, pelvic fins, anal fins, dorsal fins, and caudal fins, and some species do not have dorsal or anal fins. The tail of a goldfish is composed of a caudal peduncle and a caudal fin, and its caudal fin shape is varied.

<> do not change all the water when changing it.

The baby goldfish is a very common pet fish, and in the past, many schools would have vendors selling this fish to students. This fish is not very large, so it only needs to be usedSmall fish tanksJust raise it. It's just that many people always raise fish and die one by one, which may be caused by improper breeding methods.

1.First of all, we must understand the habits of small goldfish

Fish also have a sense of territory, so it is best not to raise multiple small goldfish at the same time in a small fish tank, otherwise it is easy to bite and other behaviors, and some small goldfish will die because of this.

2.Second, choose a fish tank

Fish tanks are usually made of glass, with round mouths, square mouths, etc. It is important to note that the size of the tank has a lot to do with the number of fish in the farm. Don't keep multiple goldfish at the same time in a small fish tank with a round mouth, preferably no more than three.

On the one hand, it is because of the limited space, and on the other hand, it is afraid that there are too many of them and it is easy to quarrel.

3.Change the water

We usually use tap water to raise this small fish, but be careful not to throw the fish in after each water change. It is best to let the water dry in the sun for a period of time to remove chlorine from the tap water. It is best not to change the water completely, leaving about one-third of the raw water.

If you have just bought the fish, it is best to place the fish tank in a relatively quiet environment, and you don't need to rush to feed them for the first two days, so that they can slowly get used to it for a while.

1. Put some washed coarse sand in the fish tank, don't feed it often, change some sun-dried water for about 5 days, and the released water is best to dry in the sun and then put it on for a day and then change it for the fish the next day, so that the bacteria in the water will be much less, the fish will not die easily, and a little salt is also a good means of prevention.

2. It is best to have a small filter, goldfish do not have high requirements for oxygen content and water temperature in the water, but with a filtration system to ensure the stability of the water quality of the small fish tank.

3. The summary is: change the water once every 4 days or so, don't feed often, and pay attention to the water quality.

You can buy an air pump to raise goldfish, which is also a common method for raising goldfish in small tanks. When the water is muddy, you can use a hose to pump out the water at the bottom layer, and it is enough to change only one-third at a time, and put half at most. Put 0.2 percent of the salt in the water.

The daily feeding amount should not be too large, you must know that goldfish are not starved to death, only to die. In addition, you can lay a layer of coarse sand or fine stones on the bottom of the water to better purify the water.

What kind of fish do you raise, and you must have a filter, if it is a tropical fish, you also need a heating rod, it is very troublesome to raise fish, you have to implement it, and you can buy a poop smoker. Don't change the water too often, because they are already familiar with the bacterial environment there, and it would be good to change it by a third at a time.

I can only raise small ones, and I have to change the water every two days.
