If you want to watch the puffer fish live a healthy and happy life at home, you need to follow the following principles:

Principle 1: Minimize their stress. Stress will destroy their immune system and make them easy to get sick. Establishing a comfortable family and living environment for them is a good way to relieve stress. You might as well arrange something for them to hide in the jar. Aquatic plants with broad leaves, caves and heavy trees are a good choice. These little guys will be more active in the evening and at night. During the day, they usually like to hide and rest. In addition, constant water temperature and PH value are very important for them, because they are actually very sensitive. Besides, they like the house with bottom sand. Of course, filtration and water flow are also necessary, but the water flow is slow, maybe they like quiet. It is also important to choose the right partner for them. We can choose suitable playmates for them by considering factors such as body shape and habits. Of course, there may be unexpected situations. For example, little guys often do them a little harm or simply eat them as snacks. If his playmate is fierce, then the little guy may bear it for a while, and if he can't bear it, he will fight with his opponent, who is either dead or seriously injured. After all, the little guy is not easy to mess with. There is something called tetrodotoxin in his body.

Principle 2: Give the kids the right food. The little ones are carnivorous. They don't eat plants, and rarely eat all kinds of artificial feed. The above food can't provide the nutrition that the little ones need to grow up. Usually, frozen or fresh blood worms, earthworms, shrimps, shellfish, crabs, squid and snails are all their favorite foods. Be careful not to overfeed, which may lead to constipation. They often pray for food, even if they are full. Because they love to eat so much, if their bellies get very big, it means they eat too much. You can feed them 1-2 times a day. Usually, their stomachs will collapse a few hours after feeding. If their stomachs are always bulging, then your little guy may be constipated.

Principle 3: always check the physical condition of the little guy. As a daily habit, carefully check the whole body of the little guy every day to see if there is any possibility of external diseases, bites and injuries caused by parasites, bacteria and fungi. By the way, observe their activities and see if their actions are abnormal. One of the advantages of this routine inspection is that the little guys will know you soon. When you come to the tank, they will hover and swim up and down in front of you. Pay attention to several bad signs:

1. He has a bad appetite. Actually, the little guy is very greedy. If he is found to have a bad appetite or picky eaters, there must be something wrong.

2. Press the line. If you find dark gray lines between the back and abdomen of the little guy, these lines can extend from the mouth to the tail, which is also an unwanted sign.

3. For the type of white belly, if the little guy's belly turns black and the color deepens, you should also pay attention.

4. Under normal circumstances, the color of the little guy's back will change with the time of the day and other factors, but if the color of his back gradually darkens, it will not become a normal body color for a long time, which is also one of the danger signals.

If problems are found, carefully check the living environment of the little guy (salt temperature filtering PH, ammonia and nitrite concentration). If there is no problem, make sure that there are no other terrorists (some big fish) in Tanqueray, and Tanqueray has enough hiding places for him to rest. If all the above conditions are normal, it is necessary to carefully check his body for physical damage.
