My fish have never had much energy, and the cold water fish I raise are always not energetic

Fish are the same as people, are big bullying small, strong bullying weak, every time after feeding always the big eat more and occupy more, eat more and eat more, he grows fast, eat less, or simply can't eat, she grows very slowly, so vicious circle, the size is getting more and more disparity, so in the future feeding process, you take it out and feed it alone, he can eat until he eats and can eat enough, he grows fast, and when it grows to the same size as other fish, you can grab food, you can eat enough, he is also spiritual.

You mentioned that this situation is also in my domestic fish, and I thought it would also be a disease. However, it has been observed that there are changes gradually, and it is still necessary to change the water frequently and try not to keep too many other species of fish together!

If you don't have any spirit, maybe he is not particularly good about the current environment, you need to provide him with a more comfortable environment.

Hello, some fish are sick may be the presence of internal fire, can not be seen in the appearance, is not energetic, it is recommended to isolate the sick fish alone, with some anti-inflammatory drugs, flowers, birds and fish markets are sold.

The water should be changed frequently, and there should be an oxygenation pump, and the number of feeding should be reasonable, not too much and not too little.

It's possible to get sick. Fish are very active if they are not sick. It can be observed. I used to raise red crucian carp at home, and I don't know what the name was, and in the end I was able to feed them to death. Some died of support, and some died of illness.

It should be that there is a lack of oxygen in the water, and the fish will look unrefreshed.

Where to buy it, consult the fish seller, they will definitely have a way.

Fish also have physical strength and lifespan, they may also get sick, or they may not adapt to the environment, and I personally think you still don't have to worry.

If you can't find the reason for a long time, it is recommended to test the water quality If we are raising medium and large ornamental fish, after half a month in the tank, it is still this half-dead virtue, then, the first thing to do, or test the water quality is better. The pH cannot be said to be unimportant, unless it is too acidic or too alkaline, otherwise, ordinary ornamental fish can also adapt. The main test should be whether the content of ammonia nitrogen or nitrite exceeds the standard, we assume that the ornamental fish is not in good condition, if everything is normal, it does not matter if the test is not good.

There may be several reasons why fish are not spiritual:

1. The water quality is not good, so it is recommended to change the water.

2. If there is a lack of oxygen in the water, or the oxygen content is low, it is recommended to increase oxygen.

3. The fish are hungry.

4. If the fish is sick, it is necessary to carefully observe whether the appearance of the fish is abnormal, or the eating situation is comprehensively determined.

First, there are some problems with the water quality, or there is a lack of oxygen.

Second, if you eat coloring materials, if you eat too much, it will be poisonous, and the toxins will be excreted from the body.

Third, the fish feed may be damp, and the fish feed will deteriorate.

Fourth, it may also be related to fish density.

Fifth, the temperature is too low in winter, and the fish activity is weakened.

There is a lack of oxygen in the water, or the water temperature is too low.

Water quality, don't overfeed, add a small amount of salt, and change the water regularly.

1.Check the water temperature, if the temperature is too low, the tropical fish will not be energetic, through the observation of the heating up, it is better to keep the water temperature of small tropical fish at 25-26 degrees, and the water temperature to save electricity cannot be lower than 24 degrees.

2.Check the water quality to see when the water was last changed, how many fish there are, and whether the water has a noticeable fishy smell or turbidity. Change some of the new water.

If you have a bare tank, you can consider putting some salt.

3.Look at the fish for obvious injuries and diseases, such as white spots, rotten fins, etc.

First of all, the water temperature is 28 to 30 degrees.

Secondly, whether the water quality is turbid.

Third, whether to feed or not.

Fourth, whether you are sick or not, etc., etc.
