【Fisherman's Point of View】:
This article summarizes all the food in the mouth of goldfish fry for the reference of the subject.
The "Gourmet Compendium" of the newborn little goldfish
Hatch the shrimp of the harvest year
Freshly hatched shrimp are the best open food for goldfish fry, and shrimp are rich in nutrients and can fully supply fry nutrition for smooth growth. Goldfish fry are very willing to eat, the best excellent open fish food, there is no one.
Egg yolk water
Many aquarists use egg yolk water to feed freshly swimming goldfish needle fry, and egg yolk water is also one of the main foods for goldfish fry openings. The use of egg yolk water to feed fish fry to extra control the amount, small seedlings in fact can not eat much, do not feed too much, egg yolk water feeding too much easy to cause water quality corruption, easy to cause the whole tank to extinguish, it is difficult to hatch the fry, the group is a pity.
Muddy water
Water is slightly opaque, the main component is grasshoppers, grasshoppers are also the open food of fish fry, water is generally cultivated by taking seeds, straw boiling liquid, because grasshoppers are hermaphrodites, and reproductive ability is very strong, there is a little nutrition, the right water temperature can be multiplied in large quantities, so that you can fish out the water to feed the fry.
Dehulled dried harvest shrimp
There is also a kind of shelled shrimp, this is not a live shrimp, is dry, is a chemical method of separation of the shelled shrimp, fry will be relatively hard to eat, personally feel that eating this feed goldfish fry seems to have a slightly higher mortality rate, therefore,
water flea
Also known as bungee, red bungee and other names, in the water a jump, so its name is bungee, bungee mature after the fry to eat slightly larger, but bungee breeding rapidly, newborn bungee is still more suitable for goldfish fry to eat.
Goldfish nursery food
When the goldfish grows to about two centimeters, you can change to feed red worms or pellets, feed the red worms more nutritious, grow faster, and if the fry are difficult to eat, you can also cut and feed.

Shrimp hatching method for harvest years
Hatching the shrimp has three elements, brine, aeration, suitable temperature, the salt used here is not the fine salt of iodized salt used for cooking at home, but the lake salt coarse salt, the hatching of the shrimp step
Step 1: Equipped with salt water.
Generally, one spoonful of salt per liter of water is almost enough to meet the salinity required for shrimp eggs to hatch in a good year.
Step 2: Add the eggs of the harvest shrimp to be hatched.
Remind everyone that when the shrimp eggs are not used, they should be stored in the refrigerator refrigerated layer.
Step 3: Aeration of the air pump.
Bubbles can be bubbled one second at a time.
Keep the water temperature around 28 degrees Celsius,
It can be placed in a fish tank with a heating rod and hatched after 24 hours to hatch the shrimp.
How to make it in water
Straw cooked and sterilized, put into aerated water, put into a place with sufficient scattered light for about three or four days, the water will appear slightly turbid, slightly white mist, not very transparent, this is the water.
Hydra rearing methods
Water fleas should be raised in shallow pots, to have oxygen supply, do not aerate too quickly, flea species can be fed fish leftovers, can be fed yeast water for it to grow, yeast water should be light and not thick, a little is enough, can not feed too much, easy to occur water quality deterioration, water flea death.
Extended reading 2: Precautions for raising goldfish fry
Goldfish fry are first hung on the wall after birth, at this time do not need to be fed, they have a little yolk in their stomachs, which can be used for their short-term growth, and after the needle fry swims flat, they must start to use open food to feed.
Slow drip water change
The goldfish needle fry stage is really very fragile, changing the water straight to the water can definitely take the small life of the fry, even if it can persist, it will be washed away by the current, and the physical strength is consumed, which is easy to cause death. Therefore, the water should be changed by drip, the water should be changed little by little, and the water change time should be extended, so as not to affect the normal survival and life of the needle seedlings.
It is best to filter with a low-speed water goblin and draw the bottom out of the dirt every day
Goldfish needle fry can be raised in still water or water goblin filtration, it is recommended to use water goblin, both filtration effect and oxygenation effect, killing two birds with one stone. Similarly, due to the fragile properties of the goldfish needle fry, the filtration can not be too powerful, it is best to control the water goblin intake speed, low speed intake, do not let it churn more and more, as the fry grows up gradually accelerate the intake speed to strengthen the filtration,
Feeding should be diligent and should be small
Feeding must not be too much, one is that the fry can not and will not eat more, the other is that the food that cannot be eaten will spoil the water and affect the life of the fry. Feeding is still necessary to adopt the strategy of eating fewer and more meals.
Don't be short of oxygen
The number of hypoxia can be regarded as the disaster of the extinction of small fry, especially the density of rearing at the fry stage is basically large, and as the fry gradually grows, it is necessary to increase oxygen, and it is easy to lack oxygen.
