I have prepared an 80 40 40 fish tank, ready to learn to raise koi, ask the masters!

The 3rd floor is a little amateurish, raising koi can not put the scavenger, one is the problem of bacteria, the other is that the scavenger hurts the fish, or the koi fish kill the scavenger. With the size of your fish tank, it is slightly smaller, and it is recommended to raise no more than 6 koi fish of about 10cm, because koi are highly polluted fish and have too much excrement. Fish farming should first raise water, establish an effective filtration system, theoretically your filtration system should be more than one-third of the volume of your fish tank, filtration is divided into drip filtration and overflow filtration 2 kinds, each has its own advantages and disadvantages, it is recommended that you go to the novice version of the Zhongjin Club to see the relevant introduction, with a search on the line.

Insist on changing the water every day, but not more than one-fifth of the total water body, and the temperature difference should not exceed 2 degrees. Koi fish are raised in a bare tank, which means that they do not put any decorations, such as pebbles, aquatic plants, etc. The new fish should be put into the water after the purchase, which means that the fish should not be put into the new tank in a hurry, first put the fish into the water tank with the plastic bag, so that the water temperature becomes the same, and then gradually put the water in the tank into the plastic bag, with the intention of letting the fish adapt to the new water quality.

Let's talk so much first, and then ask if you have questions...

Hello lz! If you want to raise koi, it is best not to put too many decorations, install a strong water circulation system, prepare high-quality feed, do not buy those cheap, and fish should be raised in an odd number, and place a "scavenger" to clean the spoils in the fish tank. And avoid putting it in a dark place, because when the fish just started farming, they are afraid of humans, and there will be a move to jump out of the fish tank in the afternoon and evening, often look at the fish tank, protect the safety of the fish and prepare some Japanese yellow powder, if the fish has received a wound, sprinkle some yellow powder after a few days**.

No need to break into the tank, direct breeding, filtration is divided into two layers, the lower layer of glass ring or coral stone (large) does not need to be cleaned, change the water and the like to clean the upper layer of filter cotton. It is better to transplant if there are nitrifying bacteria.

Filter tank Aeration pump In addition to this, it is best to bare the tank so as not to scratch the fish Raise the fish first Raise the water before buying the fish Buy a small cheap tank first It is best to let him hang in it to produce flora . Let's do that first, it's complicated.

40 * 40 * 27 = 43,200 cubic centimeters, which is about liters when converted into liters.

Generally, one liter of water raises one centimeter of fish.

Your tank has 43 liters, and 15 cm can raise 2-3 pieces, and my personal recommendation is still two, because this is the outer diameter of the rigid, and the inner diameter may be much smaller.

It is also necessary to consider the volume occupied by auxiliary equipment such as oxygen pumps, circulating water, etc.

Raising two is almost the same, it is big, you should raise traffic lights, red zebras, peacocks and these small fish, because yours is a round tank is not easy to filter, it is best to choose a waterfall filter with suitable horsepower.

When the age of the fish may be a little small, and the density certainly can not be beaten and the tank is small koi.

It's definitely not big, and the ornamentality will be reduced, and it is not recommended

An 80 cm tank can raise 3-5 koi fish with a length of 20 cm, but the growth rate of koi is relatively fast, and if they grow to 40 cm, the number of koi fish should be reduced. Koi fish can grow to 100-150 cm when they are adults, and it is best for keepers to change the large tanks when they are adults, so as to ensure that they can grow normally. If you raise a young koi in an 80 cm tank, it will limit their growth.

The 80 cm fish tank can raise 3-5 koi fish with a length of 20 cm, which belongs to the normal feeding density, and if the keeper wants to raise more, the oxygen and filtration can be strengthened. However, the size of koi fish grows relatively quickly, and when they reach 30-40 cm, the breeder needs to reduce the number of feeds or replace the large tank. Because koi fish can grow up to 100-150 cm, keeping them in an 80 cm tank will limit their growth.

1. Water temperature: Koi do not have high requirements for water temperature, as long as the water temperature is between 20-32, they can live. However, they are sensitive to temperature differences, so keepers need to use a heating rod to keep the water temperature constant.

2. Water quality: Koi carp do not have high requirements for water quality, and they all survive when the pH value is between, but the pH value that is most comfortable for them to live in between. Breeders can keep the water quality in this range and change the water frequently to ensure that the water quality is clean.

3. Feeding: Koi is an omnivorous animal, you can feed some bloodworms, shrimp, nematodes, lean meat and other animal feed, and then with some synthetic feed. Regularly feeding some algae, young vegetables and other foods can improve immunity.

4. Space: The size of koi fish can reach meters when they are adults, and the keeper needs to give them a sufficient space to ensure that they can develop better.

OK. It can meet the free movement.

The giant koi consumes a lot of oxygen and produces a lot of garbage in the water body; The baby koi has low oxygen consumption and produces less garbage in the water body. No need to explain.

The size of the fish tank is determined according to the number of fish raised. Generally, the depth of the tank above the meter can meet the needs of raising small koi fish at a depth of more than the meter. However, if you want to keep a very large koi, and not just one, you need to pay special attention when making a fish tank, and the key is to satisfy the koi carp to roam freely.

3 koi more than 40 cm, 6 small koi of 10 cm, the size of the fish tank is, this is a relatively crowded breeding density, the growth rate of koi is relatively slow, so for the problem of how to raise koi fish in the fish tank, first of all, the filter must be opened 24 hours a day, the filter also has the function of increasing oxygen, once the power fails, it is necessary to prevent death from lack of oxygen.

The warmest time of the year is in summer, and the higher the water temperature, the lower the extreme dissolved oxygen in the water body.

Assuming that the average water temperature in the north and south is 28 degrees Celsius, in order to keep the dissolved oxygen value of the water body higher than the bottom limit of 5ppm, it is recommended to raise up to 7 koi fish in a meter bottom filter fish tank. On the premise that you are mature, raising seven koi fish with a body length of 50 cm in a rice fish tank is the limit you can control. Even if your current koi is only 5 cm long, you can only keep so much in your tank.

1.There are five major skills for raising koi in a tank, the first is to pay attention to the breeding density, and you can't raise too much if the tank is small.

2.Second, it is necessary to change the water in time, generally with dried water, once a week.

3.The third is to control the water temperature, and it is advisable to keep the temperature between 21-27.

4.The fourth is that there should be enough oxygen, and you can use an oxygenation pump to inject oxygen into it.

5.The fifth is the choice of feed, which can be fed with some artificial bait.

180x70 60 fish tank with a few koi fish.

Good evening netizens, it is good to raise a few koi fish, according to feng shui, it is generally advisable to breed nine tails. In China's traditional culture, nine is the number of the supreme and yang, which has an extremely noble meaning; In Feng Shui, there is a saying that "three or three are endless, six or six are endless", the six-tailed red-top means "good luck", and the five-tailed red and white means "five blessings"; In addition, the saying of "Sanyang Kaitai" and "Shuanglong playing in the water" is also widely spread. Therefore, koi fish is prosperous feng shui, and koi fish are raised at home.

Three, six, five, nine, and two tails are all the best. For the general stocking of koi fish pond burial density, refer to the density table of koi fish stocking in fish ponds. The density of the water cluster box is generally empty, 60 cubic centimeters, 30 cubic centimeters, 15 cubic centimeters, and 6 koi carp with a body length of 15 centimeters and 20 centimeters can be stocked; 90 cubic Lu Xiao centimeters, 30 cubic centimeters, 50 cubic centimeters, can be stocked 8 tails; 110 cubic centimeters, 30 cubic centimeters, 50 cubic centimeters, 10 tails can be stocked.

I hope that you can buy a koi fish tank that suits you according to your actual situation.
