Anonymous users2024-02-07If your goldfish are spawning, first make sure the water quality is suitable. If the water quality is not good, it is essential to replace or clean the filtration equipment in time. In addition, suitable incubation equipment, such as spawning nets or lotus leaves, can be placed in the fish tank, so that goldfish can safely spawn in the branch incubator.
If you wish to preserve the eggs, you can place them in the incubator and be careful not to touch the eggs with your hands, as the grease on your hands may infect the eggs. The incubation period depends on the species of eggs, and usually ranges from 10 days a week to town. The incubator should be kept at the right temperature and water quality to ensure proper egg development.
When the eggs hatch into small fish, you need to provide enough food. Special goldfish juvenile food can be used, or finely minced shrimp meat or boiled egg yolks can be used instead. At the same time, care needs to be taken not to overfeed so as not to pollute the water quality.
Finally, if you don't want to keep the eggs or can't provide enough incubation and food, you can give the eggs to your local pet store or other hobbyists. When handling fish eggs, it is important to pay attention to hygiene to avoid cross-contamination and water pollution.

Anonymous users2024-02-06Goldfish have a swollen abdomen before spawning, and the abdomen is slightly raised compared to other fish, but it is not very noticeable. Before giving birth, they eat less food, and if they are not isolated, they will find a quiet and secluded place to stay alone, and if other fish approach, they will be expelled immediately. A few hours before they give birth, they secrete a type of mucus from their abdomen, at which point the keeper needs to transfer them to a separate container for delivery.
Goldfish's abdomen changes before spawning, first of all, it becomes larger than usual and soft to the touch. By the time they are in labor, they eat less and are less active. If the keeper has not kept them in isolation at this time, then the goldfish will find a suitable place for breeding by themselves and keep it guarded.
During this time, other fish will come forward to chase them away. Before they give birth, some mucus is also excreted from the underside of the abdomen, and goldfish reproduce soon after secreting mucus, and the keeper needs to immediately transfer them to a new breeding tank.
1. Broodstock: After the broodstock reproduce, the keeper needs to fish them out immediately to prevent them from eating the eggs. Broodstock cannot be immediately returned to the original tank and are best kept in separate containers for a few days.
Because the broodstock are relatively weak after giving birth, if they are put back in the original tank immediately, they are easy to be bullied by other fish.
2. Fish eggs: After the goldfish produces fish eggs, the keeper needs to keep the water temperature at 30, and also ensure that the dissolved oxygen in the fish tank is sufficient. In this way, they can hatch successfully in about 1-2 days.
The hatched small fry can not be fed for the first 3 days, and a small amount of shrimp eggs or cooked egg yolks can be fed after 3 days.

Anonymous users2024-02-05How to deal with the eggs after the goldfish spawn depends on whether the eggs are fertilized successfully.
Fertilized eggs: If the eggs produced by the goldfish have been fertilized, the keeper can transfer them to a separate tank and keep the water temperature between 24-26 and wait for the eggs to hatch.
Unfertilized eggs: If the eggs of a goldfish are not fertilized, they need to be fished out immediately, otherwise the eggs will become moldy over time. You can also just let goldfish or other fish eat it.
If the water temperature for incubation is 20-22, then it will take 5-7 days for the eggs to hatch. If the water temperature for incubation can be controlled at about 26, then the eggs can hatch in about 3 days. If the water temperature can be kept at 28-30, then the eggs can hatch in about 2 days.
After the goldfish eggs are successfully fertilized, the keeper can prepare a separate container for them and provide them with sufficient oxygen, so that the success rate and speed of the eggs hatching will be much higher.
Goldfish are generally warmed after the beginning of spring the following year, usually between April and June each year.

On the basis of preparing the silkworm room and silkworm tools; 7 days before raising silkworms, spray and disinfect with 1% strong chlorine, half a kilogram of medicinal solution per square meter, seal for more than 24 hours after spraying, and at the same time, spray the surrounding environment of the silkworm house should be sprayed and disinfected. About the eighth day of silkworm seed out of the warehouse, you can see that there is a small black spot at one end of the silkworm egg, called point green, a silkworm seed has 20% of the eggs point green, use the black cloth to shade the light, from the day of the point of green, the black cloth will be removed at 5 o'clock in the morning of the third day, and the light will be turned on to incubate. >>>More
Not being able to change the water will affect the eggs What big fish usually feed now, don't feed too much Once the goldfish spawns, you can take out the fish father and the fish mother, otherwise they will eat the eggs. The temperature of the water should be kept at 18 22 degrees, a little higher is not harmful, after about 1 day you can distinguish those translucent fish eggs are fertilized eggs, which can hatch small babies, and some of the other white or even hairy ones are without life factors, and the living part can hatch the baby fry after 3 or 4 days. After a long time, there are still no small fish, and it is indeed because the eggs are not fertilized. >>>More
