CATDOLL : CATDOLL: How to feed koi so they grow fast

1. How to feed koi so that they grow fast

If you want koi to grow quickly, you need to ensure that there is enough living space and water for it to swim. When raising koi, the water temperature should be controlled between 20 and 25 degrees Celsius. Secondly, you need to install a filter in the tank to ensure the water is clean and thorough. When feeding, you must pay attention to the principle of nutritional matching. Feeding carrots, red worms, bait, etc. to maintain a balanced nutrition can accelerate the growth of koi.

How to make koi grow quickly If you want koi to grow quickly, you need to provide them with a large enough living space and water body. Koi fry need to have a large enough space for them to swim. When raising them, the water temperature needs to be controlled between 20 and 25 degrees Celsius.

If you want koi to grow quickly, you must ensure that there is sufficient oxygen in the fish tank and install a filter in the tank to ensure the water is clean and clear.

If you want koi to grow quickly, you need to pay attention to the principle of nutritional balance when feeding. You can feed it some carrots, red worms, dried shrimps and other foods. Achieving the goal of nutritional balance can speed up the growth of koi.

2. The koi has grown from a small seedling to a one-year-old, and it is only seven or eight centimeters. Is this normal? Is there still room for growth?

This situation is very common. Generally speaking, it can be divided into three situations. First, the reason is the strain. Under normal circumstances, the young koi of various strains can grow to 10 to 15 cm when they are one year old. However, the koi bred from the original carp or the hybrid of vegetable carp and wild carp may not grow very fast due to genetic reasons. Second, the reason is the environment. The same koi fry of one year old grow at different rates under different breeding environments. In a large earthen pond with a large water surface, the growth rate is faster than that in an artificial fish pond; in a large ground tank, the growth rate is faster than that of a general small and medium-sized fish tank. The growth rate and size are mainly determined by the environment. Third, physiological factors. There will always be a part of the koi in the same nest that will never grow up. It cannot be seen at birth, but the difference is very obvious when they are one year old. This kind of fish is also called old man fish. It only eats but does not grow. The fish farm will eliminate it when choosing between the second and third choices, but it is difficult to see when buying fish.

I hope the answer can help you, please adopt it!

3. How big does the koi have to be to lay eggs, and how long does it take to hatch the fish?

Koi can usually lay eggs when they are 2-3 years old. Koi are oviparous animals. Male koi are almost sexually mature and have the ability to reproduce when they are 2 years old. Female fish will reach sexual maturity later and can start laying eggs when they are 3 years old. After the gonads mature, they can reproduce offspring. The cycle of gonadal maturity of koi is about one year, which means that they can reproduce once a year. April to June is the best time for them to lay eggs.

1. How old does a koi have to be to lay eggs? Koi usually lay eggs when they are 2-3 years old. Koi are oviparous fish, and female fish begin to mature sexually and lay eggs at the age of 3. Male fish mature sexually earlier, and have the ability to reproduce at the age of 2. After the gonads mature, they can reproduce naturally. Koi's gonads mature once a year, and they can reproduce once a year. April to June each year is the best month for spawning.

2. How long does it take to hatch small fish? Put the fertilized eggs into the water. Generally, small fish can be hatched within 5-7 days. After the koi lays eggs, the eggs should be taken out separately and placed in the prepared breeding tank to prevent the eggs from being eaten by the koi. During the process of hatching the fry, the water temperature should be stable at 22-25℃ to ensure good water quality and wait for the arrival of the small koi.

3. What should be paid attention to when breeding koi? 1. Parent fish: Parent fish breeding is best started in autumn, because the water temperature at this time is more suitable, mostly around 25℃. They have a strong appetite and grow quickly. You can feed them vegetables, lean meat, fruits and other foods.

2. Fertilized eggs: Fish eggs are sticky and will adhere to the tank wall. You can pick them out by hand and put them into a special breeding tank. After the fish eggs are put in, they should be observed frequently and unfertilized white eggs should be picked out in time to avoid water pollution.

4. Does anyone know what this small fish is called? The longest I caught was only the length of a finger. It likes to eat earthworms.

Ziling goby (scientific name: Rhinogobius giurinus) is a fish of the genus Rhinogobius, family Gobiidae. It is commonly known as comb goby, Ziling comb goby, Chaotianyan, goby, Jile goby, dog goby, bitter goby. It is a migratory fish, but it can also reproduce in completely closed water systems.

Distinguishing features

Small body, about 30~100mm in total length, long cylindrical. Wide head, blunt snout, front mouth. Body covered with ctenoid scales, no lateral line, two dorsal fins, pelvic fins fused into a long sucker. Body elongated and slightly cylindrical; eyes large, pelvic fins fused into a sucker. This genus is extremely difficult to distinguish species with the naked eye. It is gray-brown, with a row of irregular circular spots in the middle of the body, and a light belly; the characteristic is that the head has worm-like black-brown markings. The tail fin is round.

It lives in streams and lakes, and will slowly change its body color according to the environment. It has a strong resistance to diseases and insects, and likes to eat aquatic insects or bottom-dwelling small fish and fish eggs. It has the habit of upstream swimming and lays eggs in sand holes. It reaches sexual maturity at 1 year old and lays eggs in April and May.

Habits

It lives in temperate and tropical regions and is a bottom-dwelling fish. It is ferocious and aggressive. Its reproductive forms are divided into river-sea migratory type, where the fry hatch into the sea and then return to the river, and land-locked type, where the fish complete their life cycle in fresh water. It is carnivorous and mainly feeds on small bottom-dwelling invertebrates.

5. The difference between goldfish and tropical fish

Goldfish evolved from inland freshwater fish and can be called the quintessence of China. It has a very long history of breeding. It is relatively easy to breed and is a common ornamental fish in China.

As the name suggests, tropical fish are ornamental fish that live in the tropics. Due to regional differences, this type of fish has requirements for water temperature, water quality, etc.
