Depending on the specific incubation temperature, the fertilized eggs are slightly transparent, and other milky white eggs should be removed in time, otherwise it is easy to grow hairs in the later stage and cause water quality to deteriorate Who is responsible for the incident. The water quality of the fish egg stage is very important, and the next bit of gentamicin sterilization can be used to maintain the water quality.
Needle seedlings do not need to be fed before swimming, the yolk in their small stomachs can still support their growth, and when the needle seedlings swim flat, we need to start feeding them.
The seedling stage grows rapidly, and nutrition must keep up to prevent "zombie" old manfish.
Let's start by focusing on how to raise the newly hatched goldfish fry, that is, how to raise needle fry?
Feeding
Feeding has a big principle, it is better to feed less than more, rather than feed more than one time, so that the fragile body of the fry can resist the owner's "Ho Ho" and grow up smoothly.
Choice of food
Egg yolk water
Egg yolk water is only fed "a throw away", a small grain dissolved into the water, egg yolk water is misty, fish fry are still more willing to accept egg yolk water.
Hatch the shrimp of the harvest year
Freshly hatched shrimp are the top open grain for goldfish needle fry, and harvest shrimp also play an important role in the growth of goldfish needle fry. During the needle seedling period, the fish food was first promoted - shrimp in the harvest year.
Shelled shrimp
This is a kind of harvest shrimp that uses chemical methods to dehull, and it is recommended that non-emergency situations not be considered.
Weeds
The water made of straw solution is also one of the good open grains for goldfish needle fry. The grasshoppers are small enough that the needle seedlings are not difficult to eat.
Bungee bugs
Bungee bugs, also called red bungee, are slightly more strenuous to eat, the adult worms are slightly larger, and in fact their larvae, the newborn bungee, are loved by needle seedlings.
How to feed goldfish fry
You can feed twelve times a day, don't be afraid of the fry to die, the premise is still to feed less and feed more, filter open, change the water diligently, there will be no problem in controlling well, the fry still grow very fast, and the growth rate will definitely surprise you.
Water change and filtration
Change the water
Water change must be avoided too much, too much water change is prone to water quality turbulence. It is not advisable to change the water once for too long, and it is advisable to change it once every three or two days.
The water must be dripped, and the drops enter the water body, and cannot be greedy.
The water must be changed at the same temperature, and temperature turbulence is the nightmare of needle seedlings. You can put the water you want to change near the seedling tank for a period of time in advance, and try to change the water at the same temperature.
filtration
Filtration can not be too strong, it is recommended to use water goblin filtration, personally verify the safety and reliability, water goblin filtration is not suitable for the air pump to be fully open, needle seedling period is so fragile when a second can be a bubble.
Precautions for raising goldfish fry
The water level should not be too deep
Personally, I think that the water level of ten centimeters is enough, the fry are still very small and small, no need for deep water, deep water is a burden on the growth of fry, and it is too difficult to swim to the surface of the water to change the breath equivalent to a human climbing Mount Everest.
There are three reasons why newborn goldfish needle fry are extremely easy to cause fry mass extinction.
Water quality maintenance
Daily bottom to change the water, pay attention to the bottom, pump out food residues and fry excrement, otherwise it is very easy to cause turbid flocculents under the water, and then serious when the water quality becomes poor, affecting the life safety of fish fry.
Pay attention to oxygen supply, absolutely not lack of oxygen.
Fry hypoxia is fatal, water goblins can provide a part of the oxygen source, replacement water can also bring a part of the oxygen source, here emphasize the need to observe whether there is a lack of oxygen, whether the fry have an extraordinary situation, once found abnormal, immediately take remedial measures.
Keep the water temperature at bay
Heating rod and thermometer is recommended to keep up, the heating rod continues to work for heating, the thermometer intuitively reacts to the water temperature, which is conducive to controlling the constant temperature, it is recommended to set at about 25 degrees Celsius is more reasonable, the water temperature should avoid large turbulence, otherwise the fry absolutely can not eat, minutes can see the state deterioration.
【Summary】
The newly hatched goldfish are very fragile, which is a test of our fishing responsibility and patience, requiring us to pay absolute attention to water quality, oxygen supply and feeding, as long as we have perseverance, we can definitely raise a beautiful tank of fry.
