Goldfish have been spawning for 13 days and have not surfaced, is there a problem with small fish?

The rate of eggs hatched in this way is high. The incubation time is generally 3-4 days. The general calculation method is (100 incubation water temperature - 1 = incubation time).

2. Egg care: It is necessary to maintain the water quality, and the dead eggs and white eggs can be removed after 24 hours of artificial milking. And piles of eggs, don't be a pity.

Such a thing cannot be hatched. This work will also be carried out at any time in the next few days. Of course, this has a lot to do with the proficiency of artificial egg milking techniques.

If the fertilization rate is high, this work is easy! If the density of the eggs is not high, the water body is large enough to do without oxygen. Pay attention to the size of the bubbles and try to avoid large water currents!

3 [Special Reminder]: According to my past experience, the north incubates in early spring in early April according to the natural water temperature, and the water temperature may be about 15-17 degrees. In this way, the eggs will hatch for 5-7 days.

After the eggs hatch and fry fry, due to the low water temperature, the needles often cannot take off smoothly, if the hanging time is too long. At this time, it is necessary to decisively raise the temperature to the range of 20-22 degrees. Help the needle boy take off smoothly.

Therefore, if the water temperature is low, start using the heating rod when it hatches early to ensure the smooth development of the eggs and the emergence of the seedlings.

Do you have any male fish in your tank?

About a week after the goldfish spawn, the small fish can generally come out, and the water temperature of raising goldfish is about 15 20, so the small fish will come out in about 5 or 7 days. The water temperature is around 20 25, about 2 3 days out of the small fish, the water temperature must not be too high and not too low, otherwise the small fish will not come out.

<> If the goldfish spawn, it generally takes about a week to come out of the small fish, which needs to be decided according to the water temperature of the goldfish, if the water temperature is about 15 20 °, then about 5 7 days out of the small fish, the water temperature is about 20 25 °, about 2 3 days out of the small fish.

When the water temperature of goldfish breeding is too high or too low, it is difficult to come out of the small fish after spawning, so you need to pay attention to the goldfish eggs at all times, if you find that the goldfish eggs are white, then you will not come out of the small fish, you must control the water temperature of the feeding.

1. Generally, 3-7 days after spawning, fish larvae appear; It takes about 7 days for goldfish to appear after spawning.

2. When the average water temperature is 15-20, the number of days of incubation is 5-7 days; When the average water temperature is 20, small fish can hatch in 4-5 days.

3. When the average water temperature is 20-25, it only takes 2-3 days. In general, the lower the water temperature, the longer the incubation time.

4. If the fish in the fish tank is sure to have spawned, it has been a week, and no small fish have appeared. In general, there are the following situations.

1) If the water temperature is too low, the incubation time will be extended.

2) The eggs have not deteriorated and whitened, and the whitish eggs indicate that they have died.

3) If there is no male fish but only the larvae under the female, there will be no hatchling.

There is no male fish will not produce small fish, your goldfish will lay milky white eggs, that is unfertilized eggs, will not produce small fish. Generally, after 24-48 hours, the fertilized egg will be seen to be transparent and yellowish, which is the fertilized egg, which can produce small fish.

No, if you raise it well, you can partially hatch, it depends on luck.

Grey water is rotifers, feed for newborn small fish, don't worry too much about this, if you are a large tank, there are microorganisms in the tank, I am afraid that it is not enough, you can wrap the egg yolk with gauze, so that the egg yolk seeps out in the water for the small fish to eat.

Take care to maintain water quality.

My calves have just hatched, and I only bought two females, but only four.
