How to raise fish to live long, how long can fish live, how to raise fish to live long

Note that if the water used for fish farming is tap water, it will be left for a day, that is, 24 hours before it can be used for fish farming. Pay attention to feeding and put some aquatic plants. 1. Feeding environment, you can choose fish tank or fish pond breeding.

Different fish, the requirements are also different, if it is a goldfish, goldfish is a cold-water fish, the demand for oxygen is great, enough space and dissolved oxygen is the key to ensure the healthy growth of the fish. 2 Water quality, most common ornamental fish have strong adaptability to water quality, so the water quality in most parts of China is suitable for breeding. For those of us who are aquarium fish lovers, "raising fish first and raising water first" is a wise saying, and it is convenient to raise fish after raising water.

3 Feeding, many people will ask, how many times a day should I feed? In fact, there is no standard answer to this kind of question, don't feed blindly, and change it according to the situation. For the fish that you have just bought, don't rush to feed them, and feed them after 1-2 days.

Most of the fish raised at home are fed feed, and the feed is not as good as live bait, so we should often feed some fish insects, water earthworms, etc., which not only fish love to eat, but also help fish color. It is best to soak and disinfect the live bait with potassium permanganate, and then wash it before feeding the fish. Feeding once or twice a day is fine, without overfeeding.

Live bait can be fed more, and the fish will eat their own proportions and will not be full. Fish will die because they eat artificial feed, and the feed will swell when exposed to water. After the fish eats the feed, the feed swells in the stomach, so the goldfish survives.

If you can't grasp the amount of feeding, you can feed the feed equivalent to the size of the head of the fish 1 2, so that not only the fish will not be hungry, but also not easy to die. When you can grasp the amount of feeding in the future, you can increase or decrease the amount of feeding yourself. If the fish are sick, they should be fed less or at a later rate to avoid waste or water quality.

4. Change the water, generally you should change the water about once a week, and it can be longer in winter. Generally, it is enough to change 1 to 3 at a time. Carry out a full tank water change every 1-2 months.

If there is a sudden lack of water or the water is easily dirty, you should immediately change the water completely and adjust the water change time according to the actual situation. The new water that has been cooled must be used to change the water, and the water temperature cannot be plus or minus 2 degrees related to the water temperature of the original tank. Another:

In order to prevent fish diseases, we should prepare some common medicines, so as not to need them from time to time, generally the following medicines can ** most of the common fish diseases, you can use different drugs according to your own needs. Salt: It will be available at home, which can be disinfected and can also prevent and control a variety of ** or gill protozoan parasitic diseases, water mildew and bacterial fish diseases.

Furazolidone (also known as dysentery): It has a broad-spectrum antibacterial effect, is most sensitive to Escherichia coli and dysentery bacilli, and is effective against gram-negative bacteria. Potassium permanganate:

Disinfect fish tanks or utensils. Effective against parasitic or bacterial diseases. When soaking fish, the concentration should not be too large, because potassium permanganate has a certain corrosiveness and is very harmful to the gills.

Gentamicin: It is also a very commonly used fish medicine, gentamicin is used together with dysentery, ** enteritis effect is better.

There are many types of fish, and the lifespan of different species of fish is also different. Among them, the lifespan is relatively long, such as whale sharks, which can live for about 70-100 years, ordinary sharks can live for 30 years, many large ornamental fish, such as Arowana, can live for more than 10 years, monk fish can only live for 5-6 years, and small fish have a shorter lifespan, generally only 2-3 years. If you want to live a long time, you must first have good water, suitable water quality and water temperature, and also pay attention to feeding.

The lifespan of different fish is often different and is usually related to body size, the larger the fish, the longer it will live. Like the largest fish, the whale shark, it can live up to 70-100 years, while the average shark can live for about 30 years. Some fish in captivity, such as Arowana, can live for decades, like monk fish can only live for 5-6 years, while smaller fish have an even shorter lifespan, like guppies, they can only live for 2-3 years.

1. Maintain water quality: If you want to let the fish live for a long time, the first thing you should pay attention to is the water quality. Different fish have different requirements for the pH and hardness of the water body, so it is necessary to pay attention to regulation, some like weak acidity, and some like weak alkaline.

It is important to avoid fluctuations in water quality, which can lead to a stress response and death in severe cases.

2. Pay attention to water temperature: fish have requirements for water temperature, some wide-temperature fish, although the range of adaptation is very wide, but it is best to keep the water warm, not to mention tropical fish, usually controlled between 20-30. The water temperature should also be stable, as if there is a large temperature difference, it will also be detrimental to the health of the fish.

3. Regular feeding: Fish must pay attention to feeding, according to the different eating habits of the fish, it is also important to choose the right feed, otherwise it will lead to unbalanced nutrition, so that the life is not long.

1.First of all, when the fish is dying, we must consider whether the place we choose to put the fish is too small, and the fish pot is too small to cause the fish to survive for a short time.

2.Secondly, when the fish is dying, it is necessary to change the water of the fish in time and change it to clean water. Storing water for a long time will also cause the fish to survive for a short time, so if you want the fish to survive well, you must be diligent in changing the water for the fish.

3.Again, if you find that the fish is dying and has turned over, in addition to changing the fish to a big environment and fresh water, you can also straighten the fish and shake the tail of the fish, so that the fish can be woken up.

4.Finally, in addition to doing the above steps, no matter for a long time, it will still be circulated, at this time we can put it under the faucet, unscrew the faucet slightly, and let small water droplets drip in to prevent the fish from hypoxia.

5.If the conditions allow, you can buy an aerator.
