How to raise tropical fish raw fry?

1. Newborn small fry should be raised separately from the big fish immediately to avoid being eaten by the big fish. Newborn baby tropical fish should master feeding and changing the water, do not feed on the first day, and feed the next day. Water temperature is very critical to the growth and development of tropical fish, the suitable temperature should be around 25-28 degrees, small fish generally like old water, as long as it is not too turbid do not change too diligently, feed 2 3 times a day, each time to eat within 20 minutes is better.

Pay attention to clean up the manure and residue in time to avoid the high temperature and water quality deterioration in summer.

Second, there are several ways to feed:

1.Feed paramecium, prawns, and earthworms. Shrimp can go to the fish shop to buy eggs to hatch, and the earthworms should be cut with scissors and fed.

2.Egg yolk, you can crush it and wrap it in gauze, and shake it in the fish tank when feeding. You can also use a small portion to put it in the water.

3.Fodder. If the feed for large fish is solid pellet feed, you can grind it and put it in water, the feed will be soaked softly, and the small fish can eat it.

The larvae are relatively small, so it is ideal to catch small bloodworms or cultured 'grey water' (including paramecium) to feed, but do not feed too much to prevent damage to the water quality.

3. When changing the water, pay attention to the difference between the water quality and the temperature is not too large, otherwise the small fish will have an accident.

Fourth, the small fish is weak, be careful not to let it get sick, if you are sick, you should immediately **, it is best to use special medicine.

When the small fish is large enough, they can be raised like big fish.

There is also a knack for raising tropical fish well.

In fact, feeding egg yolk is not very good, easy to spoil the water, raising guppies is actually very simple, now you can be a little red worm, it is recommended to go to the Chinese tropical fish net, ** relatively complete, I don't understand this, or go to paste it, tropical fish.

The feeding method for newborn small fry is:Newborn fry do not need to be fed on the first day, and it does not have a yolk sac to absorb.

Usually wait a day before feeding.

You can't choose fish food for feeding the fry, its mouth is too small, and you can't feed the fish food, it is best to feed plankton, you can find a little water, and if you don't have it, feed cooked egg yolk or soy milk.

It should be noted that the amount of cooked egg yolk must be controlled, and it can be wrapped in gauze and twisted a little each time.

When the fry can swim to the surface, start feeding the lice. Water lice are fish insects that are fished in.

Worms filtered out through gauze or plastic mesh. When it grows to a centimeter or two long, it can be fed to ordinary fish insects.

Frozen harvest shrimp.

After thawing, it is slightly crushed and fed.

Artificial dry bait is slightly ground and fed.

Dried bloodworms are ground and then fed.

First of all, a constant water temperature is the key to the healthy growth of small fish. Whether it is in the growth stage, the disease stage, or the new fish fry stage, the water temperature highlights its importance all the time. For fish fry, water temperature is a life-threatening matter.

For adult fish, the water temperature generally only needs to be controlled within a certain range, and the fish can grow healthily; For fry, even a difference of 1-2 can have a drastic effect.

According to the usual experience, it is generally most suitable for the growth of small fry by slowly increasing the temperature of the suitable water temperature for adults by 1 -2. Take our most common ** Dafan as an example: the suitable temperature for adults is 24 -25, and the suitable temperature for fry is 26 -27.

At this temperature, the mustache feels warm, the frequency of activity increases, the appetite becomes better, and the growth rate is accelerated. The change of water temperature is one of the important factors leading to the sudden death of small fry. Especially when changing the water in the aquarium, be sure to pay extra attention.

Small fry are weak, and as long as the water temperature is more than 2 different, they will get sick or die because they cannot adapt.

The second is water quality, and the requirements for water quality for fish fry are higher than those for adult fish. If the water quality is not good, it can lead to an increase in the growth rate of other microorganisms and the fry will be infestation by germs. Treating small fry is a very troublesome task, and if the dose is not properly grasped, it can be counterproductive.

Therefore, the most important thing is to start at the source and eliminate water quality problems that can lead to infection.

Then there is the bait, and in the first few hours of birth, the fry begin to show a craving for food, and even swim around in search of food. At this time, you can choose to feed the larvae of the shrimp larvae to the small fry in an appropriate amount. Shrimp larvae have high nutritional value and are healthy and hygienic, which can help small fry grow quickly.

If there are no abundant shrimp larvae for the time being, only adult fish feed, they must also be crushed into powder for feeding. The principle of feeding small fry is to feed small and frequent meals, and never feed too much at once. For small fry, egg yolk is a very nutritious food, but if you are a novice fish farmer, it is best not to use egg yolk, because fish fry are very sensitive to the consumption of egg yolk, and it is difficult for novices to control the amount of feeding, once fed too much, it is easy to pollute the water quality.

The yolk that is not filtered out will decompose and deteriorate in the fish tank, causing damage to the water quality and causing the fish to die.

Finally, it is put back into the large tank, and one month after the birth of the small fry, the fish should be released from the breeding box and put back into the fish tank, so as not to have too little space in the breeding box and the fish will fight and be injured. Of course, if there are conditions, it is better to open a separate tank and raise a nest of seedlings, or raise the seedlings within half a month, because the individual difference is too great, there will be a situation of grabbing food, and even big fish biting small fish.

Egg yolks. To cook, take a small piece and wrap it with fine gauze (a dense-eyed fishing net can also be used), wet it on the water surface, and then gently pinch it with your hand on the outside of the fishing net, and the egg yolk will break, and then gently shake the gauze on the water surface a few times, so that the broken egg yolk will scatter into the water, and the small fry will start to eat when they see it. Don't do too much at a time, the fry may not be eaten after sinking to the bottom, which will affect the water quality.

This method is suitable for feeding ovoviviparous fish such as guppies, red arrows, pandas, Marys, etc.

Feeding. Turbulent water is actually water rich in paramecium or rotifers, and such water needs to be cultivated by ourselves, so I won't talk about it here. This method is suitable for feeding small oviparous fish, such as angelfish, lantern fish.

Harvest shrimp. Harvest shrimp can buy harvest shrimp eggs to hatch by themselves, or they can be directly fed to the shelled harvest shrimp eggs (the particle size is very small, and many fry can be eaten directly, which is convenient and clean). After hatching, the shrimp can be fed immediately, and over time, they will grow into large individual shrimp, and they can be fed with slightly larger fry.

This method is suitable for feeding a variety of fish, with high nutritional value, convenience, cleanliness and is not affected by the season.

The larvae of the daphnia.

That is, buy small fish and insects (cladopods, scratch feet) from the market, and put them in water basins, small jars, pet boxes, and wide-mouth containers are the best, because Daphnia will swim to a place with high oxygen content near the water surface to breathe, and if the mouth is small, it may cause suffocation and death. This allows us to harvest new white larvae from the surface overnight and feed them directly to the fry. If you want to keep it for a long time, you can add a small amount of nutrient solution (yeast powder) to the container, put it in a bright place, and change some water appropriately, so that you can provide food for small fry for a long time.

This method is suitable for feeding ovoviviparous fish such as guppies, red arrows, Marys, etc.

Rolling feed. The small pellets (small and nutritious are selected), crushed into foam with a hard card, and then sprinkled directly on the water surface to feed the small fry. This method is suitable for feeding fry over 1 cm.

When raising newborn tropical fish and small fish, they should be kept separately to prevent them from being eaten by other large fish, and it is best to use the water in the tank when the small fish were born, and then when the water is changed, the bottom of the garbage needs to be sucked out and then replaced with dried tap water.

Many friends who raise tropical fish should want to know how to raise small fish born in tropical fish. When the small fish are farrowed, it is best to keep them separately immediately, because if they are mixed with other large fish, they are likely to be eaten by the larger fish.

And when raising small fish alone, it is best to use the water in the fish tank used when the small fish are born, so that the small fish will not be unsuitable for the water quality, and the water temperature should not change too much, it is best to install a heating rod to keep the water temperature stable.

After changing the water, it is best to use a water hose to stretch into the bottom of the water, suck out the garbage at the bottom, and then replace it with tap water that has been dried to remove chlorine, and the temperature of the new water and the water in the fish tank should not be too different, change one-fifth of the water every two days, usually feed the fish and insects, so that the small fish can grow faster.
