My tropical fish are dying one after another, how can this happen?

You first need to know the basics of fish farming:

1. The fish tank should be sterilized and disinfected before use (brush it with high-concentration potassium permanganate water, and then soak the fish tank with low-concentration potassium permanganate water for about a day).

2. The selection of fish is also very important, sometimes the fish that are selected home have been sick (this requires a lot of experience accumulation, and it will not be clear for a while).

3. Take the new fish home, at this time, you should pay attention to the water temperature in your fish tank has reached the temperature that your small fish is suitable for growing (your fish is more suitable at 26 degrees plus or minus 1 degree, this is not an absolute value), do not open the bag, put the bag into the fish tank together, float for 10 to 20 minutes, and then pour the fish into the tank, do not feed it within three days, and then feed it twice a day, each time the small fish eat the best within five minutes

4. Change the water, change about one-fifth of the water every day without filtering the oxygen system, change one-third or one-half of the water for about three days with the filtered oxygen system, pay attention not to use the tap water that has just been connected, after the tap water is connected, it is best to put it for two or three days, and then change it for the small fish Because the tap water contains a large number of harmful substances to the fish Another is to pay attention to the water temperature control of the water change, the water temperature of the new water and the water in the original tank should not be plus or minus 1 degree

5. Pay attention to the problem of oxygen consumption of small fish, if there are more fish, then you have to increase the oxygen pump for oxygenation.

6. After the fish is sick, go to the fish shop in time to consult the medication situation (consult a few more, one is to increase experience, and the other is to prevent being deceived).

As the saying goes, if the water is well raised (see the water change link for details), then the possibility of fish getting sick will be greatly reduced.

Summer infectious diseases, natural disasters and fish disasters, is their fate is not good, and your fish farming technology has nothing to do, if you are interested, you can continue to raise, but it is recommended to change the fish tank or disinfect and clean the fish tank for a day or two.

1. Temperature changes, too low or too large temperature changes will bring great threats to tropical fish. 2. The deterioration of water quality and poor maintenance of water quality will also be fatal to tropical fish. 3. Sudden diseases, diseases caused by foreign substances or other reasons (including 1 and 2) are also very important reasons for the collective death of tropical fish.

Tropical fish should be diligent in observation and careful and scientific care, and if you are not careful, it will lead to extinction.

There are many reasons why tropical fish die, it can be because the temperature is too low, the water quality is too poor, or the fish are not sick in time**. If the temperature is too low and you need to pay attention to heat preservation at ordinary times, it is best to use a heating rod to continuously control the temperature, and the water temperature should be maintained above 20. If the water quality is too poor, the fish need to be changed regularly, usually once every three to five days.

If it is caused by a disease, it is necessary to observe regularly to see if there are any signs of illness, and if you get sick, you should take medication according to the condition.

1. Daily feeding: If you want to feed tropical fish, you must first ensure feeding. Usually feed neither too much nor too little.

Feeding too much will accelerate the deterioration of water quality, which is very bad for the health of the fish, and too little feeding will lead to nutrient deficiency. Usually feed three times a day, and each feeding should be eaten within 3-5 minutes.

2. Regular water change: In order to maintain water quality, you need to change the water in the fish tank regularly, even if there is filtration equipment, the ammonia nitrogen in the water will still increase, so you should change the water once a week, and you can change one-fifth of the water each time. When changing the water, you need to pump the water before you can pour the trapped new water into the tank.

3. Pay attention to the temperature: since it is a tropical fish, there are certain requirements for temperature, the minimum water temperature can not be lower than 20, for some large fish, the water temperature should be higher, at least 24 or 26 or above, and some even reach 28.
