What do they eat and how to raise them

1. The stocking density should be small, that is, try to put as few fish as possible in the tank.

2. The water for fish farming must be dried or trapped before entering the tank. Exposure to the sun for one day, or drying for three days, is to remove chlorine, which is not always important.

3. Pay attention to the water temperature difference when changing the water, the water temperature difference is more than 2 degrees, and the koi fish can adapt to 5-30 degrees Celsius, but it cannot adapt to the sudden change of the peerless water temperature.

4. The best thing to raise in the tank is the bare tank, that is, the water plants, sand, stones and the like cannot be placed in the tank.

5. Koi fish eat a lot of food and excrement, so there must be filtration equipment and oxygenation equipment.

6. Depending on the water quality, the water is generally changed once every 3 days, and one-third of the water is changed each time.

As long as the koi fish are raised correctly, they generally do not die so easily.

Koi rearing:

Maintain water quality: Koi do not have high requirements for water quality, koi have more excrement every day, you can buy a filter of dozens of pieces (24 hours a day), while delivering oxygen to filter water quality. Generally, the daily consumption of electricity is less than 1 kWh.

The frequency of water changes is once a week, one-third to one-half of a water change at a time. Do not change the water too much at one time, which will cause the instability of the ecosystem in the fish tank, and it is easy for the koi to be unadaptable. Another issue to be aware of is not to let the oil contaminate the bathtub, otherwise it is easy to cause hypoxic suffocation.

Cleaning of fish tank: If you buy the kind of fully automatic fish tank, it is equipped with a cleaning system, and you can change the filter cotton or clean it once every half a month. But koi is not so practical and complex equipment, so the fish tank is easy to grow green moss, the way to prevent green moss is to clean the fish tank often, clean the fish tank to fish out, and keep half of the water do not pour out, after cleaning the fish tank pour back.

If you don't have time to clean the fish tank often, you can put the fish tank in a cool place away from direct sunlight and put wallpaper on the sunny area.

Don't plant aquatic plants: those aquatic plants are very expensive nowadays, and if you raise koi, the aquatic plants will be eaten quickly, and the gains outweigh the losses. And eating the leftover residues can easily pollute the water quality. Aquatic plants can be raised in a separate pot and regularly put aquatic plants into the fish tank to supplement nutrients.

Water temperature control: As mentioned above, koi fish can survive the cold winter, but the vitality of the winter is relatively poor. If the weather is particularly cold, pay attention to putting some nutritious fish feed to supplement calories.

If the weather is particularly hot, feed less food, clean the fish tank more, and change the water more. When changing the water, pay attention to the water temperature, if you suddenly put the koi fish in cold water, it will be difficult for it to adapt, so put the water in the basin to cool for a while, so that the water temperature and temperature are about the same before pouring it into the bathtub.

Food: Koi are omnivores, crickets, earthworms and other insects can be eaten, and vegetarian foods such as bread crumbs and steamed buns are no problem. If you feed more, you should change the water frequently, and the more you feed, the worse the water quality.

How much feed is appropriate for a fish? This is not good, the general standard is that after feeding, the koi fish will be eaten quickly, and they will be fed a little more. If the koi haven't eaten within 5 minutes, it means that you have fed a lot.

Illumination: Koi do not need special lighting, but for sterilization, you can also buy those lamps that have a sterilizing effect and turn them on for an hour or two at night.

Many breeders will initially encounter a disease in koi, and most of the diseases are caused by water quality problems. And most koi fish will lose their spirituality to a greater or lesser extent after recovery.

1. Environment. If you want to raise a good koi, you must first raise water, and the feeding density in a fish pond should not be too large, otherwise the koi activity space is too small, and it is easy to have depressive symptoms, which is not conducive to its growth. In addition, the intensity of light and the ingredients of the feed are also the key to determining whether the koi are healthy and beautiful.

When fish lovers buy koi, the koi fish with a fat body and a non-smooth body can not be selected, and the koi fish that have just been bought back should not be poured into the fish pond immediately, the fish should be immersed in the fish pond with the bag, and let it stand for about 30 minutes, so that the water temperature inside and outside the fish bag can reach a balance, and then the fish and water are poured into the empty basin, and it can be put into the fish pond after half an hour.

2. Disease prevention. The second thing to do is to filter. Filtration is one of the factors that every koi lover must consider. Koi fish have a strong digestive system, and strong filtration can provide good living conditions for koi fish.

What fish farmers need to do is to increase the delivery of oxygen (i.e. the oxygen pump must be on at all times) and the entire filtration system must be strong.

If you want the koi to be more spiritual, you can't raise a school of vigorous koi fish with strong filtering alone. A good living environment (water quality, pH, temperature, etc.) is also very important. Although koi fish are very easy to raise, they do not have high requirements for temperature and feeding conditions, but they also have certain requirements.

The most suitable temperature for koi is 22 28, which is most suitable for living in slightly alkaline water with slightly lower hardness. In the whole breeding environment, oxygen must be sufficient, and the sudden change in water temperature should not exceed 2, otherwise it will directly endanger the health of koi.

3. Feelings. It's also important to interact with your koi. Many koi enthusiasts will say that the memory of a fish is only 7 seconds, and when 7 seconds have passed, it is a new world. I think this is because of the inertia generated by the inertia generated by feeding the koi fish at a fixed time every day, so they will swim with your movements.

It is also because of this inertia that when some aquarists ask what to do if koi are timid, many fish farmers will also tell novices that they often interact with them when feeding, and after getting acquainted with you over time, they will not be as timid as when they first came. Some koi fish do not look spiritual, because the koi is not very adaptable to the new surrounding environment, so it will show "timidity", when it adapts to the surrounding environment for a period of time, it will be much better. So the owner should also interact with it more when feeding, the next time you come to the pool, it will pester you, and your friends will also find that your koi is in good condition if they come to see your fish.

Koi fish are generally fed with animal bait, plant bait and synthetic bait. For example, animal baits include: minced meat such as lean pork, beef, mutton, chicken and duck, etc.; In addition, there are larvae of insects such as barley worms, mealworms, silkworm babies, etc.; Aquatic animals such as shrimp, small fry, nematode, earthworm, water, bloodworm, small snail, etc.; In addition, earthworms born in the soil, centipedes that have been poisoned are eaten.

Plant-based foods include vegetable leaves, cabbage leaves, etc.; melons and fruits, watermelons, grapes, etc.; bread crumbs, bean cakes, biscuits, bread, steamed bread crumbs, cooked grains, etc., that people eat; In addition, nutrient-rich substances such as egg yolk and milk can also be used as feed for raising koi; The second is algae plants, duckweed, aquatic plants and other plants that koi fish like to eat.

Koi families can raise and eat general packaged goldfish feed.

Don't buy the stall that is a small bag of one yuan in bulk, the quality is too low, and it is estimated that it is all starch.

Just buy *** goldfish feed.

Koi fish and goldfish are kept similarly. It is important to pay attention to the density of water quality, food, filtration, oxygenation, stocking, etc.
