What do koi eat to grow fast?

Koi grow fast by eating bread crumbs, fish worms, bean cakes, vegetable cakes, crab meat, duckweed and other foods. Koi are omnivorous fish, gentle in nature, easy to raise, and can be fed with general mollusks, fragments of higher aquatic plants, benthic animals, tiny algae or artificial synthetic granular baits.

The breeding of koi is similar to that of goldfish. They can be fed twice a day, and the amount of feed can be increased or decreased depending on the temperature in different seasons of each year. Generally, they can be fed fish worms, granular feed, small earthworms and other baits, but do not feed them too much. Generally, they are enough to be 80% full.

When it comes to what koi fish eat, you should feed them an appropriate amount based on the size of the fish, climate changes and water quality. It is best to feed them high-quality koi feed, which is more hygienic, has more stable nutritional content, and is better for the health of the fish.

Tips for feeding koi fish

As the temperature changes with the seasons, the feeding of koi fish also needs to be particular.

1. The weather in spring is warm and cold, so pay attention to keeping the water temperature stable. Feed mainly plant bait, and gradually increase the amount from a small amount to facilitate better digestion and absorption of koi fish.

2. In the hot summer, you should avoid feeding meat to koi fish to prevent indigestion.

3. The temperature in autumn is most suitable for the growth of koi fish. During this period, you may wish to add more animal baits, such as silkworm pupae, crab meat, fish worms, etc., to increase the proportion of koi fish's protein intake, which will help promote rapid growth.

4. The weather is relatively cold in winter, so you should keep warm, feed appropriately, maintain fat and prevent diseases.

If Koi grow fast, you should feed them more earthworms, shrimps, egg yolks, corn flour and mixed pellet feed. You can feed them one by one or alternately. Koi are quite greedy. If you feed them too much, they will suffer from food accumulation or constipation. The water should be changed frequently. If you feed more, you should change the water more often. Do not leave excrement and leftover bait in the water. If you do not change the water, the water quality will deteriorate and there will be a lack of oxygen in the water. The fish will not only lose their appetite, but also get sick.

Koi, the original species is red carp (Cyprinus carpio). Red carp, as an ornamental fish, was very popular in the Ming Dynasty. It is said that koi originated from Longzhou koi in Guangxi, Xingguo red carp in Jiangxi, and golden carp in Hangzhou, Zhejiang. It was introduced to Japan from my country in the early days. After long-term artificial breeding by the Japanese people, there are now more than 100 species. According to historical records, Japanese nobles were the first to raise koi in ponds for viewing, and it was rarely seen by ordinary people. In the early days, it was called "red carp", "colored carp" and "flower carp". After World War II, it was renamed "koi".

Best suited for home fish tanks or small ponds

In 1973, as a friendly envoy between the Chinese and Japanese people, Japanese koi settled in my country. Koi originated in China, flourished in Japan, and then returned to China. It can be said that it has experienced a process of "export to domestic sales". Today, koi is loved by more and more people for its unique masculine beauty, and is even known as the "king of ornamental fish".

Biologically, it belongs to the Cyprinidae family, which is the largest family of all fish species, with more than 1,400 species. It is a high-end ornamental fish that is popular in the world today, and is known as a "living gem in the water" and a "swimming work of art." It is popular among people because it has low requirements for water quality, a diverse diet, and is easy to breed.

It is easy to breed and raise, and its diet is quite diverse. Generally, general breeding does not require high water quality. The so-called koi refers to any carp with colors and patterns for people to appreciate. Some koi are also edible. There is a kind of koi in Wuyuan County, Shangrao City, Jiangxi Province, called the red purse carp, which can be eaten and also appreciated.

Koi is not difficult to raise, as the old saying goes; people who don't know how to raise fish can also keep koi alive for one to two years. But it doesn't mean that they can be raised in a rough manner. It should be emphasized that koi consume a lot of oxygen. If they are raised in an aquarium or other small containers, the stocking density is high, and an inflator is a necessary equipment. Koi excrete a lot, so they should be raised in a bare tank, and a water filter device is also necessary. Koi swim fast and like to jump. Decorations that may cause harm to koi and the fish tank should not be placed in the fish tank, and the container should be covered. The minimum requirement for choosing a fish tank is also 80 cm long (this tank can only hold 2 to 4 20-25 cm koi). It would be best if you can use a larger container, of course, because you have to consider the issue of whether the koi will stay after they grow up. But if you don't even have an 80 cm tank now, it doesn't matter. First successfully raise the fish, and then make plans.

To raise koi well, the key is to choose the fish. Buying small fish of 10-20 cm will have the highest success rate of keeping them alive. When choosing fish, you should see if the water is too muddy and if there are a few rotten fish in the fish school. If this is the case, you don't need to look at the fish in the pond. If you pass this level, you can quietly watch the fish you want. Do not buy fish with short and big heads, flat and blunt mouths, skinny or bloated bodies. Choose fish with a symmetrical body, active swimming posture and bright eyes. Cheap fish generally don't have good colors, as the saying goes; you get what you pay for, but the body condition is still good. After choosing the fish, remember to ask the store to add oxygen to your fish. After bringing the fish home, don't rush to open the bag. Put the whole bag of fish on the surface of the water for 45 minutes to 1 hour to let the fish slowly adapt to the water temperature, then open the bag and let the water gradually mix with the water in the bag before releasing the fish.

In the next few days, the water is most likely to become turbid. It is best to change 1/2-2/3 of the water every day. If your fish tank is too large and it is difficult to change such a large amount of water, you can use a suitable small container to temporarily keep the fish for two weeks. When you see that the fish's condition begins to improve, then scoop the fish into the permanent container. Remember to balance the water temperature of the two containers before scooping the fish. Whether it is temporary or permanent, it is best to put enough activated carbon in the water filter, which is to minimize the amount of harmful substances. After the fish are stable, if you use a small container such as an aquarium to keep koi, depending on the water quality, it is best to change 1/8-1/3 of the water every 4 or 5 days. This is very beneficial to the healthy growth of koi and keeping the water clean.

Koi can eat and poop. Different food is fed in different seasons. Generally, the feeding amount is 3%-5% of the total weight of the fish. Koi also has strict requirements on water quality and needs a powerful filtration system. Xipu titanium stainless steel filter is suitable for fish ponds of 4-100 tons.
