If the fish only swims obliquely occasionally, the situation will not be very serious, but if it keeps this state all the time, it will basically die. It should be noted that there are many reasons for fish to swim obliquely, such as being frightened, poor water quality, lack of oxygen and disease factors. Because there are too many problems, they need to be checked one by one, so it is difficult to find the cause of the disease quickly and treat it.

2. Why do fish swim

obliquely? 1. Be frightened: Fish are most likely to swim obliquely after being frightened. This is mainly because they are afraid, usually of unfamiliar environments. Therefore, they will behave in the first few days after entering the tank, but as long as they rest for a period of time, the fish will gradually feel at ease. Basically, there is no problem.

2, the water quality is not good: When the water quality is not good, the fish will feel it immediately, thus making a certain performance. It should be noted that bad water is not necessarily muddy, even if the clear water, ammonia nitrogen content is too high, it will also cause it to swim obliquely, so the clear water should be changed or changed.

3. Disease factor: If the fish is sick, it will also swim obliquely, and this disease is usually incurable. If it is found early, there is still a chance to try. If it is found late, it can only be resigned to fate. Sick fish should be isolated as soon as possible to prevent the disease from spreading to other healthy fish.
