After the goldfish spawn, how do you take care of those eggs?

What to do with goldfish when they spawn?

As the water temperature rises, the ornamental fish we raise at home also begin to enter the breeding season, which is the season when the fish reach sexual maturity.

And the fish in the fish tank are male and female fish mixed together, and there may be spawning, so how to deal with goldfish spawning in the process of breeding goldfish?

Judging from what you described and photographed, your fish laid eggs last night and there was a scavenger in the tank.

And big goldfish in it. In this case, it depends on whether you plan to breed your own fry, if you don't plan to breed fry, you can leave the eggs in the tank and let the big fish and scavengers eat them directly. However, in this case, it is necessary to pay attention to the change of water quality, and it is best to change the water appropriately or the water quality is prone to deterioration.

If you plan to breed fry, it is best to transfer the big fish and the scavenger out, or the eggs will be eaten by the fish inside, the scavenger eats the fish eggs very quickly, and the lion head in the goldfish also likes to eat the fish eggs, if the fish are not transferred away, then the eggs in the tank will be eaten clean in less than a day. After the fish is turned away, the water in the fish tank is changed some, and the water used for incubation is used as much as possible with a new water, which can improve the emergence rate of fish eggs, if this situation is encountered in the future, it is best to put the fish nest in the fish tank, and the fish will directly transfer the fish nest with fish eggs after spawning, which is better and more convenient than turning the fish.

In addition, it should be noted that the fish are usually relatively weak after spawning, so it is necessary to stop feeding for a few days and rest for a few days to allow the fish to recover their physique. At the same time, it is necessary to look for abrasions on the surface of the fish.

Because of the spawning process male.

The fish will chase the female, and the fish is very susceptible to injury, so if the fish has abrasions, it is best to use some anti-inflammatory drugs in the water.

Or apply some bactericidal drugs directly to the wound to prevent bacterial infection in the future.

3 7 days after fertilization, the larvae will break out of the egg membrane and enter the rearing stage, at which time the fish will be centimeters long. According to whether the body shape is normal, whether the tail fin is divided into four tails, etc., leave the good and remove the inferior, and put the screened larvae into the feeding pond to continue to raise. It is stocked at a density of about 50 square meters and sieved plankton is added to the pond.

If the water quality is relatively thin, kilograms of fertilizer can also be added per square meter to promote the proliferation of plankton. After one month of rearing, the fish can reach 3-4 cm.

To take care of the eggs, you need to ensure that the water is clean, and there must be no other fish to eat the eggs in this environment, and the temperature can be controlled.

First of all, you should choose a suitable water temperature, and then you can put some aquatic plants in the water to increase the oxygen in the water, and then add some nutrients to provide nutrients for the eggs.

Keep them in clean, warm water, feed them a nutritious loose meal every day, and change the water regularly.

Goldfish spawning is usually done in a single day and generally takes five to ten hours. Goldfish spawning is not done at one time, it is generally done multiple times. When goldfish spawn, it is best to put some aquatic plants in the fish tank to facilitate the attachment of fish eggs.

Unfertilized fish eggs should be fished out in time to avoid polluting the water body. After spawning, the broodstock and the eggs should be separated to prevent the broodstock from eating their own eggs. Then maintain the water temperature at 23 to ensure water quality and dissolved oxygen, and wait for incubation.

It takes about five to ten hours for goldfish to spawn and can be completed within a day. Goldfish spawn multiple times to finish spawning, not all at once. It is best to put some aquatic plants in the fish tank when spawning, so that the laid eggs will fall on the aquatic plants and will not float in the fish tank or stick to the tank wall.

Fertilized eggs will be yellow, white eggs or hairy eggs are unfertilized eggs, and should be fished out immediately after being found, so as not to pollute the water quality. Fertilized eggs should be selected and hatched separately, not with broodstock to avoid being swallowed. The water temperature of the incubation environment should be maintained at about 23, the water body should be clean, and the dissolved oxygen in the water should be sufficient.

1. After the goldfish lays eggs, they should be kept separately from the male fish and the eggs. After the mother fish lays eggs, her physique is relatively weak, and feeding them separately can protect the mother fish from the male fish chasing and attacking the female fish.

2. After spawning, the female fish should take necessary disinfection and sterilization measures. It is best to use methyl blue and potassium permanganate to disinfect to avoid worsening of infection at the production port. It is necessary to ensure that there is sufficient oxygen and suitable light in the fish tank, which is conducive to the recovery of goldfish after giving birth.

3. The water quality should be good, and the water temperature should be kept at about 20. Do not walk around in front of the tank too often, and provide a quiet environment for the goldfish.

4. The diet should be nutritious, and live bait rich in protein can be fed, such as silk earthworms, bloodworms and other live bait. Remember to disinfect before feeding to avoid carrying bacteria on the bait and infecting post-natal goldfish.

1. After the goldfish spawn, move the goldfish into the prepared new container as much as possible, if you can't find a new container and can't provide a new living environment for the goldfish, then you should also replace half of the water quality during the spawning period to ensure the stability and health of the water environment.

2. In addition, the necessary anti-inflammatory and disinfection measures should be taken after goldfish spawning, which can be disinfected with methylene blue potassium permanganate or salt to prevent the deterioration of goldfish wound infection, and at the same time, sufficient oxygen and light should be ensured, which is very important for goldfish recovery after spawning.

1. In the process of fish farming, when the fish spawn in the fish tank, the first step is to think about getting the eggs out. These fish eggs have a lot of mucus that will have a great impact on the water quality, and some unfertilized fish eggs will have a greater impact on the water quality if they are in the fish tank for a long time.

2. If you want to hatch the eggs, you can also consider transferring the fish to other fish tanks. This is good for both the fish and the eggs, and if the eggs do not move away, they will be eaten by the big fish or filtered, and a lot of eggs will be wasted.

3. Change the water. Fish spawning process will secrete a large amount of mucus and some body fluids, so the fish in the fish tank after spawning water quality will become very sticky, and this water quality will also have a great fishy smell, so whether the fish eggs are transferred or the fish are transferred to the tank, the original fish tank must be appropriately changed to water, or it will not affect the health of the fish or the emergence rate of fish eggs (in the case of hatching in the original tank).
