What courses should novices pay attention to when raising fish for the first time? Nowadays, fish farming is becoming more and more popular, and there are many aspects that novice fish farmers need to pay attention to for the first time. Everyone should be well aware of it. Let's see what courses novices need to pay attention to when raising fish for the first time.

What tutorials should novices pay attention to when raising fish for the first time 1 First of all, what should novices pay attention to when raising fish for the first time?

Beginners need to pay attention to the selection of fish tanks when raising fish for the first time, and then do a good job of opening the tank and releasing water before raising fish. The choice of fish tank is usually related to the fish to be raised. The bigger the fish to be raised, the bigger the fish tank, ensuring that the fish can swim. Opening the tank is a necessary step before raising fish, and it is necessary to disinfect the fish tank with potassium permanganate and other drugs. Next, we should cultivate nitrifying bacteria, pour the culture solution every week, turn off the lights and explode oxygen to accelerate their reproduction.

Second, what equipment does the fish tank need?

1, filter: the filter is an essential equipment in the fish tank, which is responsible for maintaining the water quality of the fish tank, especially for the health of the fish. Generally, filtration can be divided into up-filtration, down-filtration, filter cartridge and so on. Among them, the bottom filter type is used for large fish tanks, the top filter type can be used for ordinary small fish tanks, and the straw fish tank is more suitable for using external filter cartridges.

2. Oxygen pump: For fish tanks with large fish or high feeding density, the oxygen pump is also very important equipment, which can replenish oxygen to the water and make the fish breathe better, otherwise floating heads will appear. But for fish tanks, there is no problem without oxygen pump.

3. Heating rods: If tropical fish are raised, heating rods are also necessary equipment, which can raise the water temperature, keep the temperature within a certain range and make the fish grow better. Normally, the temperature should be controlled above 20℃. Below this temperature, the fish's activities and diet will be affected and even get sick.

A small amount of toxic substances will remain in the newly bought fish tank. If you add water to raise fish without disinfection, it will lead to the revival of residual bacteria. If you fish at this time, the fish will definitely have problems, so you must disinfect it before opening the tank. You can use potassium permanganate or chlorine dioxide to disinfect the fish tank, but potassium permanganate will leave color. It is generally recommended to soak in chlorine dioxide for 2-3 hours before cleaning.

Second, fill the fish tank with water and measure the leakage.

You can add water to the cleaned fish tank. Directly add water for more than half a cylinder, conditionally add trapped water and unconditionally add tap water. This is not only to raise enough water to ensure the survival rate of subsequent fish, but more importantly, to detect whether there is water leakage in the corner of the fish tank. If so, you can communicate with the seller in time or choose after-sales service.

Third, the choice of filter materials is not bad.

The filter material must be of good quality. The quality of filter material mainly depends on two points: 1, whether the filter material falls off slag, and 2, how permeable the filter material is. The slag loss of inferior filter media is serious, while the slag loss of high-quality filter media is almost zero. Although the effect of cultivating nitrifying bacteria is equally divided, the cheap filter material is easy to pulverize and has a greater impact on water quality.

In addition, the filter material with good water permeability can breed nitrifying bacteria well, thus achieving the effect of purifying water quality. As a reminder, the newly bought filter materials can be dried for a few days. Sterilizing filter materials with ultraviolet rays is the simplest and most environmentally friendly method.

4. First use fine filter material, then use coarse filter material.

After disinfection, the filter material is slightly soaked in water and put into the filter box. The main filter materials are filter cotton, ceramic ring, time ball and bacteria room. The filter cotton is mainly responsible for physical filtration, and the ceramic ring is used to interrupt the water flow, which is beneficial to better culture nitrifying bacteria in the timely ball and bacteria room.

Five, cotton filtration is the most important.

Filter cotton is the most important equipment in physical filtration. Whether the filter cotton can be used well is the key to directly determine the quality of water. The best way is to separate dry cotton from wet cotton and change it regularly, which can effectively remove most of the magazines in the water and ensure the cleanliness of the water.

Six, pump oxygen open.

After the filter material and filter cotton are put away, it is necessary to turn on the water pump and oxygen pump to explode the oxygen in the water tank and let the whole water cycle flow, so that the digestive system can be established more quickly. It is convenient for the fish behind to adapt quickly,

Seven, fish into the tank for a week and a half.

After the nitrification system is gradually formed, the fish can be put into the tank at this time. The fish in the tank need to put some solid small fish that can eat and pull, so that the fish excrement can better promote the establishment of nitrification system. Generally, small fish can get into the main fish after staying in the fish tank for one to two weeks until they die.

Eight, super warm water does not pour water.

When the main fish is lowered, it should be overheated first. Overtemperature means putting it in a fish tank with the bag to keep the water temperature in the bag consistent with that in the fish tank. Usually soak for 30 minutes. The next step is to pass water, that is, add the water from the fish tank to the bag to make the fish adapt to the water in the fish tank.

Every 5 minutes or 10 minutes, add a small amount of fish tank water to the fish bag. When the fish get used to it, take it out of the bag and put it in the fish tank. Never turn the whole bag upside down and pour it into the fish tank with the fish and water. There will be some impurities left in the bag, so you'd better take it out and throw it away.

What tutorials should novices pay attention to when raising fish for the first time?

There are many kinds of goldfish in the market, such as tropical fish and cold water fish. Some of them look good and expensive, while others look ordinary and affordable. For the novice fish breeder for the first time, it is suggested to start with the easiest fish to feed, such as grass goldfish and butterfly tail, which are not only cheap, but also easy to feed.

Don't be greedy, the fish tank should be big.

Fish farming needs a fish tank. Relatively speaking, the bigger the fish tank and the larger the water body, the greater the survival probability of goldfish. Beginners should not be greedy for fish, just keep three or five. The fish tank should be as big as possible, so that the fish can swim freely in it, and there is enough space and oxygen.

Pay attention to water quality

The water quality of fish farming is very important. If you use tap water to raise fish, you should pay attention to connecting tap water to dry three days in advance to let the chlorine in tap water evaporate. In addition, pay attention to observation when raising fish, and pay attention to changing water when the water quality is turbid. Generally speaking, water can be changed once every three days or so, or some water can be changed appropriately according to the water quality.

It is not easy to feed too much.

There has always been controversy about the breeding of goldfish. Goldfish can survive without feeding for a long time, but if you want to raise beautiful fish, you should feed them regularly. I suggest you feed it once a day, and don't feed it too much. Feed two or three fish for two minutes. You can feed the fish you haven't eaten in two minutes, so as not to affect the water quality.

Hypoxia or not

It is best to use oxygen pump to raise fish, so the survival rate is higher. If you don't have an oxygen tank, you should pay attention to the state of the fish. If you often float up and spit bubbles, it may be lack of oxygen. You can put aquatic plants in the fish tank to produce oxygen and increase the number of water changes.

Observe more and find it early.

With the change of seasons, goldfish will also get sick. It is easy to grow mold in fish tanks in summer and infect goldfish. Therefore, everyone should observe goldfish more, find problems as soon as possible and solve them as soon as possible.
