I believe many people have raised goldfish. The beautiful patterns and small figures of goldfish swim around in the bathtub, but if one day you suddenly find that the tail of the little goldfish in your aquarium is rotten, what should you do? You must be surprised. Why did the goldfish tail suddenly break? How to solve it? What will happen if we don’t treat it in time? In fact, if not treated in time, it will not only lead to the complete decay of the tail of the goldfish, but also lead to the direct death of the goldfish. So we should find out the cause in time and treat it symptomatically.

So the problem is, why does the goldfish tail suddenly rot? The reason is generally that when we change the water source for goldfish, the temperature difference of water is too large, or the water quality of the water source has not been changed for too long, and the water quality is too dirty. It may also be caused by goldfish fighting and biting. Goldfish are very susceptible to bacterial infection after injury. Generally, they will be infected with mold, and then mold will cause water mildew, which will lead to mildew and necrosis of the tail of goldfish. In the early stage, it usually shows that the swimming is relatively slow, the appetite is not good, and even no longer eat. Then slowly, the tail is necrotic. Generally, the connective tissue will crack, just like a broken broom.

If the tail of a goldfish in your family is broken, the first thing you have to do is to isolate that goldfish from other goldfish to prevent other goldfish from being infected by it. Because most of the rotten tail is due to the problem of water quality, the first thing to do is to change the water, but not all at one time, because if you change it all at one time, the temperature difference will be large, so the fish will be more seriously injured. Therefore, it is recommended to replace about one quarter of the water source at one time, and then disinfect the goldfish. If it is the initial stage, we will use salt to increase the concentration of water. But if it is particularly serious and the tail begins to rot, use the medicine immediately. Generally, copper sulfate or potassium permanganate solution is used until its condition improves. When it is treated, it should be fed with more feed from live animals, which can make it better faster. Then proper sun exposure is also beneficial to its recovery.

So how to prevent the phenomenon of rotten tail of goldfish? The first thing to ensure is that the water quality of its life should be very good. Then properly avoid direct exposure to the sun. When feeding goldfish, be very careful not to hurt its scale membrane and body. Special attention should be paid to bacterial infection and parasites. The above is the solution to the rotten tail of goldfish. I hope it can help you. Also remember to be more careful when feeding at ordinary times, because rotten tail disease will endanger the life and health of goldfish, but it will affect its beauty.
