The fish in the tank have spawned, what should be done

In the case of fish, if the eggs are transparent, it proves that they have been fertilized; If it is white, it is moldy or unfertilized. If this situation requires a water change. Because the eggs spoil the water quality and the smell is very fishy.

If they are normal births, you can find a tube with a smaller diameter to suck out the seeds and sperm and put them in the water with stones and leaves, do not put anything else, pay attention to bask in the sun as much as possible, and wait for them to come out on their own. Go ahead, don't let the big fish eat the roe!

If you have a goldfish.

Crucian. Carp.

Or other spawning fish.

If the eggs are transparent.

Proof that fertilization has been achieved.

If you turn white.

It's already moldy. Or.

Unfertilized. If this is the case.

A water change is required. Emptying.

This is because fish eggs can spoil the water quality.

And the smell is very fishy.

If the goldfish has laid its eggs on an extractable item, prepare the hatching tank, take out the item with the eggs and the raw water directly, and put it in the hatching tankIf there is no raw water, the water environment in the incubator is the same as that in the original tank as much as possible.

If the goldfish lays their eggs on the inner wall of the fish tank, they can only be quickly isolated and replaced with the raw water in the isolation area, a small oxygen pump can be configured, and the water temperature can be kept at 16 18, and the small fish can be seen in about a week.

The goldfish laid their eggs on the filter, which could not be intervened manually, because the filter could not be stopped, and whether the eggs on it could hatch into small fish was left to fate.

Pre-spawning care of goldfish.

1. Disinfection. Before the goldfish are moved to the outdoor feeding, the fish pond (tank) should be disinfected and soaked with salt boiling water or potassium permanganate solution, filled with new water, and appropriately mixed with some green water, so that the pool (tank) water quickly turns tender green, and must pay attention not to let the water temperature rise or drop suddenly.

2. Potting. Within one or two days before the pot, the goldfish broodstock should stop eating or eat less, because the digestive function of the goldfish that has just woken up from wintering has not yet **, and the change from indoor to outdoor environment, the goldfish can not fully adapt for a while, so the feeding should be less and gradually increase.

3. Disease prevention. The spring temperature is just right for the reproduction of some parasites and bacteria that harm goldfish in the water, and a small amount of salt (3-5 grams of salt per 50 kg of water) or a small amount of cytoxin, kanamycin, etc., can be put into the water to prevent and cure diseases.

Answer: If the eggs in the tank are fertilized, you can wait for them to hatch, and if they are unfertilized, you should take them out and clean them out in time. Fish are oviparous animals, and most of them are fertilized in vitro, so females need males to fertilize to become fertilized eggs after spawning. If there is no male fish fertilized, the eggs will slowly rot, which will affect the water quality and is not good for the health of the fish, so it is necessary to clean them.

Ask a question, but something else is eating fish eggs.

Answer: If the eggs in the tank are transparent, it proves that the eggs in the tank are fertilized eggs. If the fish are going to eat the eggs, it is best to prepare a new tank, and put the roe in a separate tank, and the water in the original tank should also be changed.

Note: Ensure that the oxygen supply is sufficient, ensure the external conditions such as light and water temperature, and wait for the eggs to hatch after a few days.

The eggs are all at the bottom of the fish tank.

Question: Take the fish out?

Eggs are not easy to catch.

Just isolate them and ask questions.

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).

Goldfish are observed after spawning.

Within 48 minutes after the goldfish spawns, you can basically see the combination of sperm and egg and the combination of sperm and egg and the combination of non-fertilized are light yellow and transparent, while the unfertilized egg is milky white, and the combination of non-fertilized eggs can be removed to prevent the normal egging of all things.

Control temperature: The suitable temperature for goldfish eggs is around 16 18 degrees Celsius, and the time is 6 7 days, if the natural environment is stable, the fish will immediately egg, and the physical fitness will be better. The breeding fish used for breeding should also pay attention to protection, appropriately supplement nutrients, and fully prepare for the next egging.

Don't blindly change the water after the goldfish spawn!

If you want it, remove the big fish and let him hatch, and change the water immediately if you don't want it, otherwise you will soon get sick.

Change to a larger fish tank, if the fish tank is large enough, add some seaweed, this is to increase the oxygen content in the water, and wait until the small fish grow up to do the above actions, because the small fish are easy to die when moving around.

Speaking of aquarium fish.

I believe that many friends are no strangers, with the improvement of economic ability and the progress of life taste, more and more people like to breed ornamental fish at home in order to add interest to life. Although it is said to be an ornamental fish, they can also spawn after being farmed for a long time. Generally speaking, if the aquarium fish is spawning on the tank wall for the first time, then it is okay to leave it alone and let the aquarium fish eat the eggs themselves.

Usually, if you mix some oviparous ornamental fish in a tank, whether it is a small goldfish or a mini parrot fish.

They can be left alone when they lay their eggs for the first time. Because like the first nest of small fry, the overall survival probability is very low. If the farmed ornamental fish cannot completely eat the eggs produced, or the eggs appear moldy and white, at this time, some treatment measures should be taken.

You can pump the bottom of the fish tank to change the water, this treatment method is also very simple, you don't need to use a pump, you only need a small water pipe. In addition, for the eggs laid by ornamental fish on the tank wall, we can also take out these eggs to hatch, and find a special fish tank for hatching fish eggs. Generally speaking, if the water quality of the tank where the eggs are hatched is relatively good or the water body of the tank is relatively large, then oxygen is not required.

On the contrary, if the water body is small and the water quality is poor, then you can provide a certain amount of oxygen**, and at the same time pay attention to the temperature difference of the good water.

In addition, when hatching the eggs, try not to keep the water level of the tank too high. During this period, it is best not to change the water quality and adjust the temperature, and it will probably not be long before the hatch can be successfully hatched. In addition, the spawning ornamental fish can also be brought out together with the eggs, and the fish can hatch the eggs themselves.

However, it should be noted that if there are other species of ornamental fish in the tank, then this method will not work, and it is likely that these small fry will be eaten by other fish.

To raise fish eggs separately for hatching, there must be hatching eggs, for example, the fish tank of goldfish is laid with aquatic plants, and the fish tank of mini parrot fish has steel cans and small teapots.

At this time, it should be given adequate feed and nutrients, otherwise it will eat the eggs or small fish inside.

These eggs can be fished out and placed in a clean basin of water to wait for hatching.

Goldfish may die after spawning. The main reason is that the goldfish after spawning will be weaker and will die easily. In addition, if the operation is not done properly in the process of reproduction, such as the water temperature changes drastically during the process of changing or flushing, the goldfish is also prone to death.

In addition, there are more germs in the water during the breeding season, and goldfish are prone to diseases. Finally, there is the problem of dystocia, which can also lead to the death of some goldfish. <

Goldfish need a large enough space to breed. It can also lay eggs in fish tanks. During the breeding season, there need to be both male and female fish in the tank, and when the time comes, the female fish can spawn.

In this process, it is necessary to keep the water temperature suitable and the amount of dissolved oxygen in the water to be sufficient.

Goldfish may die after spawning, but not all goldfish die. Specifically, there are four main causes of goldfish death. The main reason is that goldfish will consume a lot of physical strength after spawning, and their physical strength will be very weak at this time.

In the process of laying eggs, it will also affect their normal eating, so after laying eggs, their physique will become very poor and they are easy to die. Second, if it is not considered to be done properly during the breeding process, it will also cause the goldfish to die after spawning.

Specifically, there are many situations, such as a drastic change in water temperature during the breeding season, or a sudden change in water quality, which will cause goldfish to not adapt and will catch a cold. The result may be a direct cessation of spawning, or a direct death after the spawning. Third, it may also be that there are more germs.

In the breeding season, the water temperature is more suitable, and the water temperature is not only suitable for goldfish, but also for the growth of some germs, and goldfish are easy to die after being infected with germs. Finally, there is the problem of dystocia, if the goldfish is spawning, it may also die.
