Zebrafish is a low-temperature low-oxygen fish can live in 10 degrees of water than guppies are easier to raise than guppies It is the best breed for novices to start with Change the water depends on the feeding density The more fish you raise, the more you feed the faster the water is dirty If you raise less Half a month to change it is no problem Generally everyone is changed once a week or so Change the water can not change the whole tank will die fish Look at the turbidity of the water You can change one-third or two-thirds Regardless of which stage you can feed red nematodes Daphnia Harvest shrimp Artificial feed, etc Water is the foundation of fish survival Because water is the necessary condition and environment for fish survival Even if you don't feed it for 5 days, you may not die But if the water is dirty, the fish will be easy to get sick Unless there are some feeds that can increase body color and disease resistance I don't know if it contains chemicals I think feeding live bait grows fast (this is the experience) artificial feed is slower But it is hot in summer, fish and insects are easy to die If you feed it is not fresh, it will be bad for the fish You can also feed artificial feed and fish insects alternately Nutrition will be more balanced If you are referring to newborn small fish All tropical fish Regardless of whether it is large or small, you can feed egg yolk water, daphnia, abundant shrimp larvae, artificial feed, etc.
-
If you look at the turbidity of the water, if it is good, it will be changed every 4 to 7 days, and if it is bad, it will be changed every 3 days, and the more fish you have, the higher the degree of turbidity.

Zebrafish reproduce once every 7 days, can reproduce 6 7 times a year, and can continue to reproduce under the premise of a suitable environment. Breeding is generally possible after 3 to 5 months of age, and at 4 months of age in a suitable food and environment. Female zebrafish can generally lay 100 300 eggs at a time, and after the female is found to have spawned, it needs to be isolated and reared so that it can spawn smoothly.
Zebrafish reproduce once every 7 days, but can only breed 6 7 times in a year, the frequency of zebrafish reproduction is relatively fast, under the premise of a suitable environment, it can reproduce continuously, if the breeding environment is poor, it will not reproduce continuously. Therefore, during the breeding period of zebrafish, it is necessary to provide a comfortable living environment and ensure that food and nutrients are sufficient.
Zebrafish are generally able to reproduce after 3 to 5 months of life, and the time to sexual maturity is shorter than that of other fish. If the living environment is comfortable and the food is sufficient, breeding can be carried out in 4 months. If there is a lack of food and a poor breeding environment, it can also enter the state of reproduction at the age of 5 to 6 months.
Female zebrafish spawn after one week of gestation and the number of eggs per spawn is between 100 300. In addition, the zebrafish will have a larger belly before spawning, and their temper will become irritable, and they will even swim behind the male.
-
Usually only one feeding in the morning is sufficient. When I raised it, I fed it once a day, and there was nothing abnormal. If you want to grow faster, you can feed less often, and you can feed two or three times a day.
-
A zebrafish can be fed every five or six hours during the day, and the amount of food put in each time should be eaten within three minutes.
Zebrafish is a hardy fish with low water quality requirements, and it can grow well in water above 10 degrees. Zebrafish have a docile temperament and are suitable for polyculture with other species of tropical fish, and zebrafish mainly eat animal bait. Juvenile fish can distinguish male and female at two months, and sexually mature at six months.
Zebrafish can reproduce 6-8 times a year.
If the fish tank is small, it is necessary to change the trapped water once a day or two, and if the fish tank is medium, it is necessary to change the water at least once a week.
-
Once a day, feed too much fish tank will be very dirty, the water is best changed once a week, this kind of fish is not easy to raise, it is easy to braid, two Fridays ten are all gone.
-
All ornamental fish raised in the fish tank are recommended to be fed less, once a day or once a day or two days can be.
-
I feed it once a week, and it's not dead, so embarrassing.
-
Zebrafish are fed 2 or 3 times a day, respectively in the morning, noon and evening, feeding, you can choose dry feed or fresh fish, shrimp, bloodworms and other foods. Increasing the amount of dissolved oxygen in the water can effectively promote the feeding of small zebrafish, and the water can be changed for 3 to 4 days after adding the filter, and 30% of the total water volume can be changed each time.
Zebrafish do not pick food, as long as it is fresh food, whether it is dry feed or fish, shrimp, bloodworms, etc., zebrafish will eat, it needs more nutrients, so it should be fed every day to promote its growth and development, you can feed them 2 3 times a day, after each feeding, pay attention not to let the feed remain in the water, thus affecting the water quality.
You can add an aerator to increase the amount of dissolved oxygen in the water, because the oxygen content in the tank is sufficient, in order to effectively promote the feeding of small zebrafish, after adding the filter, you can change the water once every 3 4 days, and the amount of each water change is 30% of the total water volume.
The body length of zebrafish is generally 3 4cm, so the choice of fish tank does not need to be too large, choose the length, width, height of 40cm. The bottom of the fish tank is paved with pebbles, which plays a role in beautifying the fish tank and purifying the water quality, and increases its resting place to a certain extent, and controls the water temperature at 20 26 when feeding.
-
Zebrafish can change the water once a week because they are not strict in their requirements for water quality, and they are not seriously polluted by the water quality, and in the case of filtration systems, the keeper can change the water once a week. If the density of feeding is high and the water pollution is more serious, the frequency of water change needs to be relatively high, and the water can be changed once every 3-4 days. However, the amount of water change should not be too much at a time, and it can be controlled at one-third of the total water volume.
Zebrafish can be changed once every 7 days under normal rearing. Because zebrafish do not have strict requirements for water quality, and the pollution of water quality is not serious in the process of raising them, and many breeders will install a circulating filtration system, so the frequency of water change does not need to be too high. However, if the density of feeding is high or the water pollution is more serious, the breeder needs to increase the frequency of water change, and the water can be changed once every 3-4 days.
When changing the water for zebrafish, you need to remove the garbage and food residues in the fish tank first, and the amount of water change should not be too large, and the amount of water change can be controlled at one-third of the total water volume each time. In addition, it is also necessary to pay attention to the temperature difference between the new water and the old water when changing the water, preferably not more than 2.
Zebrafish does not have high requirements for water quality and can adapt to weak acid, weak alkali and neutral water. Keepers usually use tap water to raise them, before using tap water, keepers need to expose to the sun for 2-3 days, which can effectively remove chlorine in the water and avoid affecting the health of zebrafish. Breeders can choose to use river or lake water to feed, but river and lake water is prone to pollution, and keepers need to filter it many times before they can use it for zebrafish.
-
The tank needs to be cleaned and disinfected before changing the water for zebrafish, and then the chlorine in the tank can be removed after 3 days of resting in tap water, and then the digestive system can be established to put it in the tank. Once the zebrafish is in the tank, it is important to provide a quiet environment to avoid being frightened. Zebrafish should not be fed on the first day of the tank, and the zebrafish will gradually regain their appetite on the second day.
The tank should be cleaned and disinfected before changing the water for zebrafish. After that, the zebrafish can be put into the water after 3 days of resting in the tank to remove the chlorine in the water, and then nitrifying bacteria are added to the water, and the nitrification system is established after continuous oxygen injection for 24 hours.
Once the zebrafish is in the tank, it is important to provide a dimly lit environment to prevent it from being frightened. After a few days of life, the zebrafish will be able to adapt to the environment and start rearing normally.
On the first day of the zebrafish in the tank, it is not advisable to feed it, it is necessary to observe its state, and the state of the zebrafish will gradually recover a little after entering the tank, and there will be a phenomenon of looking for food. If the zebrafish is not in good condition, you can put an appropriate amount of salt water in the tank to relieve the symptoms.

Zebrafish in captivity are generally about 4-6 cm long, they are small fish with a more lively personality. Although they are tropical fish, they are relatively hardy and can grow well as long as the water temperature is above 20. If you want them to grow bigger, you need to feed them more nutritious food.
It is also necessary to ensure that the environment in which they live is stable, so that they can develop in size. <
Most of the zebrafish in captivity are between 4-6 cm in length when they reach adulthood. They belong to the small tropical fish and are not very demanding for the environment. As long as the environment in which they are kept is comfortable, they can grow and develop well.
Although they are tropical fish, they are relatively hardy and can grow larger as long as they live in a large enough space. If you want them to grow bigger, it's best to feed them more nutritious food. And make sure that they live in a comfortable environment so that they can develop better body shape.
The lifespan of zebrafish is relatively long, and they can reach 3-5 years when they are bred in captivity. They are less difficult to raise, and they can live up to about 10 years in a more comfortable situation. However, it is difficult for zebrafish to reach about 10 years in captivity, and it is generally 3-5 years.
In addition, the lifespan of zebrafish in captivity can be affected in many ways. For example, if the water quality is too poor or the temperature difference is too large, it will cause them to get sick. Frequent illness of zebrafish can also affect their lifespan, and if you want them to live longer, you need to reduce the chance of them getting sick.
In addition to this, whether the living environment is comfortable or not also has a certain impact on their lifespan. When they are bred in captivity, it is also necessary to ensure that the environment in which they live is comfortable.

Zebrafish do not have high water requirements, and breeders can choose to breed in tap water. The freshly connected tap water has more chlorine, and the breeder needs to expose the tap water to the sun for 2-3 days, so that the chlorine can completely volatilize. They also do not have high requirements for water quality, they can live together in weak acid, weak alkali and neutral water, and the breeder can keep the pH value between and change the water every 5-7 days to ensure that the water quality is clean.
Zebrafish can be farmed in tap water, and they do not have high water requirements, as long as the water is clean and refreshing. However, the freshly picked tap water has chlorine, and the keeper needs to expose it to the sun for 2-3 days, which can reduce the impact of chlorine on zebrafish. Breeders can also choose some well water, river water or lake water, but these kinds of water are prone to contain impurities, and breeders need to clean up before use.
Zebrafish also do not have high water quality requirements, they can live in weak acid, weak alkali and neutral water, and when bred in captivity, as long as the pH value is kept in between, they can grow normally. If the keeper wants to ensure that their water quality is clean, it is best to change the water every 5-7 days, and the amount of water change is controlled at one-third of the total water volume each time.
1. Water temperature: Zebrafish are tropical fish and prefer a higher water temperature. When they are bred in captivity, they need to use a heating rod to keep the water temperature between 24-26, and this potato chop sample can make their life more auspicious and comfortable.
2. Feeding: Zebrafish are omnivorous fish, and breeders need to feed them more animal feed, so as to ensure that their nutrition is sufficient. Breeders also need to feed them some synthetic feed on a regular basis to make them nutritionally balanced.
3. Oxygen: Zebrafish have a high demand for oxygen, and the keeper should regularly give them oxygen to ensure that the oxygen in the water is sufficient.
If there is a filter, if the water quality is good, you can change it once every 3 or 4 days, and pay attention not to have a temperature difference when changing the water, otherwise the turtle will easily catch a cold. >>>More
The time of oil replacement is related to what oil you use, just use the oil well, I use GT engine oil, 15000 kilometers to replace it, the throttle is more comfortable than other oil, the power is enough, go to the official website to buy it directly to the auto repair shop to change, directly give a working fee of about 100 yuan.
Black Mary fish is an ovoviviparous fish, and the black Mary fish has a strong reproductive ability, and can reproduce once every 4 6 weeks, giving birth to 10 50 larvae each time; Just after giving birth to larvae, females need to rest alone for about a week, raising and breeding some precious species of black Mary fish, it is more difficult, mainly to ensure excellent living conditions, keep the water fresh, but can not often add a large amount of new water.
Phalaenopsis can be cultivated for 5-8 years, if you want Phalaenopsis to survive for a long time, you need to replace the cultivation substrate every 1-2 years, you can use the cultivation substrate made of moss, coconut bran soil and sandy soil, and in the Phalaenopsis growing season to apply 1-2 times of nitrogen, phosphorus and potassium compound fertilizer to promote the differentiation of plant flower buds. >>>More
Generally, the automobile oil filter element is replaced once every 5000 kilometers. However, the metal debris generated during the operation of the parts, the dust that enters, the carbon deposits that are oxidized at high temperatures, and some water vapor will continue to be mixed into the oil, and the service life of the engine will be reduced after a long time, and the normal operation of the engine may be affected in serious cases. >>>More
