How to raise newborn goldfish is a question every fish lover wants to ask. The following is the method of raising newborn goldfish that I will introduce to you. Let’s take a look.

How to raise newborn goldfish How to raise newborn goldfish:

The Dazaolahe family selects small goldfish through layers of screening, and only keeps the small goldfish with beautiful bodies and healthy development. For novices who raise small goldfish, when selecting, they must carefully distinguish the physical condition of the goldfish.

The first thing to do when selecting goldfish is to know the best time to select them. The first time to select goldfish is about 15 days after they are hatched. When the young goldfish grow to about 1.5 cm, you can change the water for the goldfish and then select them. The goldfish you select this time should be healthy. All goldfish with single tails and other physical defects should be eliminated.

The second time to select goldfish is about one month after they are hatched. At this time, the goldfish has grown to about 2 cm, and the fins of the whole body have developed completely and the appearance is obvious. Therefore, the goldfish selected at this time should also be healthy. The goldfish with single tail, partial tail, or incomplete dorsal fin should be eliminated and all of them should be eliminated.

The third time to select goldfish is about 2 months after they are hatched. At this time, the goldfish have basically taken shape, their bodies have fully developed, and the characteristics of each part of their bodies and their fins are clearly developed. At this time, we should select goldfish seedlings with a regular and symmetrical body shape, a four-open tail, and obvious good traits. Goldfish with physical defects should not be selected.

How to keep small goldfish: changing water

When the small goldfish are just hatched, they should be separated from the big goldfish to prevent them from being eaten by the big goldfish. Generally, the small goldfish are kept in the original tank, and the big goldfish are moved to another container. Don't change the water frequently at this time, because the small goldfish have a weak ability to adapt to the environment when they are just born.

During this period, put in an air pump to oxygenate and maintain the oxygen content in the water. After feeding the first meal after 3 to 5 days, change the water for the goldfish the next day. Use a small spoon to transfer the goldfish to the new tank. The water temperature must be consistent so that the goldfish can adapt. This completes the first water change.

If the tank is large enough, you can put a water sprite in it to use very small water flow for oxygenation and filtration.

After that, it is time for some rebalancing exercises. Move the fish every 15 days or so, and be gentle in all movements. After about 2 months, the fish will be about 1.5 cm. Before each water change, be sure to disinfect with potassium permanganate and rinse. The temperature of the water should be consistent from beginning to end.

How to feed goldfish:

Most of the newly born goldfish are attached to water plants, while some sink and lie on their sides at the bottom of the fish tank or pond without moving. They have weak mobility and sometimes rely on the swinging of their tails to swim vertically intermittently while the fertilized eggs develop.

Do not feed within two or three days because the nutrients in the yolk sac have not been fully absorbed and the baby will not eat.

At this time, do not disturb the hatching tank, the water in the pool and the fish nest. This will cause the small fry to fall to the bottom and be easily covered by various impurities and die.

Three or four days after hatching, the goldfish's yolk in the yolk sac has been absorbed and its digestive system has been fully developed. Now it can swim horizontally in search of food.

At this time, you can take out the yolk from the boiled eggs, wrap them with one or two layers of gauze, twist them with your hands and shake them gently on the water surface for the goldfish to eat. Generally, feed them once or twice a day, and do not feed too much each time.

When the goldfish can swim freely to the surface of the water, you can feed them some "gray water". Gray water is small fish worms that are invisible to the naked eye. You can use a fine nylon net to sift the fish worms on the water surface to let the small worms leak through the mesh, leaving larger fish worms such as sword water fleas to feed the adult fish.

After one or two weeks, when the goldfish grows to more than 1 cm and its swimming ability is enhanced, it can be fed fish worms or palatable artificial bait.

Tips and methods for raising goldfish: 1. Choose the goldfish variety.

There are many varieties of goldfish, and the key is to choose the one you like. You can go to the flower and bird market to buy whatever you like. It is not difficult.

2. The size of the fish tank.

Choose an appropriate fish tank according to the size of your office or desk. It is best to choose a square or round fish tank that is not too high. Determine the number of fish to raise based on the size of the fish tank.

3. Change the water frequently.

The fish tank in the office is generally not too big, and the water is not too much, so it is convenient to change the water. Because the fish tank on the desk is generally not oxygenated, the water quality will deteriorate over time, and the oxygen in the water will decrease, affecting the survival of goldfish.

4. Feed the animals.

Go to a goldfish store to buy special goldfish feed and feed it regularly. However, in general, cold-water fish are easier to raise, so the amount of feed should not be too much, as too much will make the fish digest poorly and may cause problems.

5. Pay attention to treating fish diseases.

Fish, like humans, can also get sick. If one fish is sick, it must be isolated from the other fish and treated with special medicine.

6. Understand some basic common sense.

When raising fish in the office, cold-water fish are generally chosen. Tropical fish need to be heated in winter and are not suitable for office feeding. Understanding some basic living habits of goldfish can help you better raise the fish.

How to feed little goldfish If we want to feed little goldfish, we need to know what they eat. Most newly born little goldfish cling to water plants, while some sink and lie on their sides at the bottom of the fish tank or pond without moving. They have weak mobility and sometimes rely on the swinging of their tails to intermittently swim vertically to develop fertilized eggs. In two or three days, since the nutrients in the yolk sac have not been completely absorbed and they do not eat, do not feed them. At this time, do not disturb the water in the hatching tank, pond, and fish nest. If you disturb them, the fry will fall to the bottom and be easily covered by various impurities and die.

Three or four days after hatching, the yolk in the yolk sac of the goldfish has been completely absorbed, and the digestive system has been fully developed. At this time, the goldfish can swim horizontally and look for food. Each owner has to decide what the goldfish eats. At this time, you can take out the yolk from a boiled egg, wrap it with one or two layers of gauze, and gently shake it on the water surface with your hands for the goldfish to eat. Generally, feed it once or twice a day, and do not feed too much each time.

When the goldfish can swim freely to the surface of the water, you can feed them some "gray water". Gray water is small fish worms that are invisible to the naked eye. You can use a fine nylon net to sift the fish worms on the water surface to let the small worms slip through the mesh, leaving larger fish worms such as sword water fleas to feed the adult fish. If the gray water supply is insufficient for a while, you can still use egg yolk instead. Whether feeding egg yolk or gray water, you must put a small amount of live fish worms in the fish tank or pond of the goldfish so that they can swallow the dirt in the water and improve the water quality.
