How to raise fish in a fish tank?

1. Three days before buying fish, the fish tank should be taken care of. First, add salt to the fish tank and then fill it with two-thirds of the water for soaking. The purpose is to disinfect the fish tank and allow the new fish to have their own health. If you have a clean home, just soak it for a day, and then expose the fish tank to the sun for two days, and the fish tank will be finished.

2. If there is nothing arranged in the fish tank, it will be a "naked tank", which is not very beautiful. It is best to put some gravel at the bottom of the fish tank, plant some aquatic plants, and put some decorative items to increase the ornamental value of the fish tank. In addition, aquatic plants not only beautify the fish tank but also provide oxygen to the fish.

3. The newly bought fish are very fragile, so after putting the fish in the fish tank, except for feeding, try not to look forward for two days. This will scare the small fish. Wait until two days later Once the fish have adapted to the new environment, you can enjoy them. In addition, it is best to place a light above the fish tank at night because some fish do not like darkness.

4. When you change to a new environment, you must control the temperature well and prepare a thermometer. Generally, the most suitable temperature for fish is 22-24℃. If the temperature is too high, the fish’s food intake will decrease, so stop grow. If the temperature is too low, the fish's food intake will decrease and they will stop moving, which is not conducive to the growth of the fish and is not conducive to viewing.

5. In winter, you must prepare a heating rod, otherwise the temperature in the fish tank will be very low and even the small fish will freeze to death. There is a temperature range on the heating rod that can be controlled at a temperature suitable for fish growth, which is very convenient.

6. Feeding is generally done once a day, and at a regular time, either always in the morning or always at noon. When feeding fish, pay attention to: feed more when it is cold, feed less when it is hot, and do not feed when it rains. Hello. Don't feed too much at one time. Feeding too many fish will cause the fish food to sink to the bottom, which will damage the water quality.

7. Change water frequently. The water in the fish tank is usually changed once every three days or a week. Remember not to change the water in the tank. The water to be replaced should be prepared in advance the day before the water change. The purpose is to ensure that the temperature of the water to be replaced is not much different from that of the water to be poured in. Pump out a little more than one-third of the water, and then pour in the water prepared in advance.

8. Fish disease prevention and control is very important because some fish have diseases and can easily be transmitted to other fish. Generally, sick fish will have symptoms such as damage to their body or gills, white spots on the body, and stop eating. Most of them are due to infection with parasites. At this time, the sick fish must be isolated quickly and the water should be cleaned and changed. , clean out the parasites. Afterwards, you can buy some medicines to treat sick fish according to their symptoms.

Raising water quality

Predecessors of goldfish farming have long had the experience of "raising fish first, raising water", which shows the quality of the water. It will directly affect the normal growth and development of goldfish. The purpose of changing the water is to remove dirt (garbage, fish feces, remaining feed, and old impurities) in the water, keep the water clean, adjust the water temperature, and increase oxygen in the water, thereby stimulating the growth and development of goldfish.

If you want to raise goldfish well, you must have a preliminary understanding of the fish farming water:?

Salary

Refers to the tap water that has just been released, which is used for fish farming. Water is ideal. However, it should be noted that the water temperature is often very different from the water temperature in the fish pond (tank), and temperature adjustment treatment is required (the tap water in some areas contains a lot of chlorine and needs to be dechlorinated).

Old water

It is the dirty water containing feces and dirt at the bottom of the fish pond (tank). Including the feeding water in the pool (tank) that has not been changed for a long time. It has a great impact on the growth of fish.

Old water

is the general name for clean and tender green, green, old green or green-brown water in fish ponds (tanks). Among them, tender green water is the best. There are more green algae floating in the old water, which are also good supplementary feed for goldfish. This kind of water has less putrefactive and decomposed organic matter and more dissolved oxygen. Fish are often raised in tender green and clean old water. The fish raised have the strongest appetite, strong body, bright color and rapid development. ?

Returning to clear water

If you find that the old green water in the original pool (tank) suddenly turns into clear water, and many green algae settle at the bottom of the tank, this phenomenon is called returning to clear water. . This kind of water can easily cause fish diseases and needs to be completely replaced.
