Why do my goldfish always grow small?

20 degrees water temperature, feed twice a day. Every two days, a third of the water is exchanged. Feed nutritious synthetic feed and grow up.

Goldfish themselves grow more slowly, so be patient with fish pets.

Why don't the goldfish in the fish tank grow big? The reason why the goldfish in the fish tank don't grow big:

1. The fish tank is too small and there is no space, and it is difficult for the fish to grow up.

2. When buying fish, I bought an old fish, which has passed the age of growing up and cannot grow up again.

3. Only feed ordinary fish feed, general feed will cause malnutrition.

So I didn't grow up much.

4. Goldfish are not large goldfish in the first place, they may be small species.

Additional instructions: 1. Place the glass cylinder in a ventilated and sunny place near the window. It is necessary to pay attention to the stocking density, according to the size of the container, reasonable arrangement, rather less than more.

Because the indoor air circulation is not large, the water is easy to be turbid, which is easy to cause goldfish to die due to lack of oxygen. If you have an air pump.

If you find that the goldfish has a floating head, you need to open the air pump to oxygenate, especially at night, you need to be oxygenated.

2. The bait used in fish farming is live fish and insects.

The most ideal, the water quality is not easy to deteriorate, feeding dried fish and insects, synthetic pellet feed can also be. Now there are live fish and insects on the market**, but it is also troublesome to buy them every day. For the dried fish and insects sold in the market, you should choose relatively fresh and loose particles to feed the fish, and do not buy old and moldy dried fish and insects to feed.

Artificial pellet feed is better to use full price feed with complete nutrients, and it is sold in the market.

3. In order to keep the water quality pure, the amount of bait should be strictly fixed and quantified, usually 1 to 2 times a day is appropriate, and the amount of bait should be eaten within half an hour, and the bait should not be fed too much.

The goldfish in the fish tank are all for appreciation, they grow very slowly, and it takes several years to see them grow bigger. Fish can't see how they grow up in a short period of time, because whales are small animals that are appreciated and generally grow very slowly.

Goldfish don't grow big, they don't feed well, and their nutrition can't keep up. Second, the space of the fish tank is small, and the third is poor water quality, and the long-term state of the fish is poor. Wait a minute.

Many species of goldfish are so big even if they are adults, and there are many under five centimeters, and no matter how well you feed them, the genetic restrictions are so big that you can't continue to grow.

Because the goldfish, itself is very slow, he is not some other animal? So the goldfish itself is small.

There are many reasons why the goldfish in the fish tank are not large, and the following possibilities can be analyzed:

1.The space is too small, and the range of motion of the goldfish is limited, and it cannot grow effectively.

2.The quality of the food is poor, and if the raw materials of the fish food are of poor quality, it will cause the goldfish to not grow long after eating, and even lead to death.

3.There is a lack of filtration and a stable growing environment, which is more conducive to the growth of fish.

4.The water quality is not suitable, such as the instability of pH value, ammonia content, nitrite, etc.

5.The environment is not suitable, such as water temperature, light, etc.

6.Improper feeding, such as overfeeding, overfeeding, etc.

7.Disease problems, goldfish can also cause not to grow when they are sick.

It is not impossible to raise goldfish in a fish tank, Yilanshou.

For example, first of all, there must be a large body of water, and secondly, it is necessary to create an environment suitable for goldfish, such as green water, green algae in green water is the natural food of goldfish, which can reduce the feed cost and feeding times in the process of artificial feeding.

Or fish bugs. This kind of food, although this can provide better conditions for the growth of fish, but it limits the value of ornamentation, so in general, goldfish for ornamental purposes are difficult to raise very large and fat.

Goldfish, also known as golden crucian carp, is an ornamental fish that evolved from crucian carp. There are many kinds of goldfish, and their body length naturally varies.

Reasons: 1. Your fish tank is too small, and it is difficult for fish to grow without space;

2. You bought an old fish when you bought fish, this kind of fish has passed the age of growing up, and it is impossible to grow up again;

3. Only feed ordinary fish feed, and the feed of general source envy will be malnourished, so it will not grow much; The crack is high.

4. Your goldfish is not a large goldfish, but may be a small species.

Methods: 1. Change the water every other day;

2. Control the water temperature;

3. Wipe the fish tank clean, wipe the fish tank with raw taro, then add water, and wait for the fish tank to grow with water moss to stock goldfish;

4. Separate the large and small fish, and put two or three male fish in one tank;

5. Small fish are crushed with boiled egg yolks and fed.

1. It may be that the fish breeding space is small, or the fish food is not good, it is recommended to feed live fish insects, or a well-formulated goldfish feed. It is recommended to feed the fish 2 to 3 times a day as well.

2. Goldfish are small animals, and the growth rate cannot be rushed, even if it is a little longer, it is difficult to see.

3. Before looking at the product, some fish belong to the Pinhui species that do not grow up, so they will not grow up.
