When we breed guppies, we may observe the phenomenon of guppy's rotten tail. Then, this kind of situation generally speaking is the guppy got sick, is called "the rotten tail sickness". The disease needs to be treated in a timely manner, so measures should be taken to treat the symptoms in time, otherwise the symptoms will become more and more serious, and may also affect other fish in the tank. If the disease is not particularly serious and in the early stage of the disease, it can be treated with salt. Sprinkle salt in the water tank once a day for three consecutive times, and you can probably cure it, but this is only for the initial stage of the disease. If the disease is in the middle or even late stage, then salt generally does not work, need to be treated with special drugs.
In the "rotten tail disease" in different stages, the use of drugs is not the same. As mentioned above, if it is in the early stage, it can be treated only with salt. If the disease is in the middle, the available drugs are yellow powder, erythromycin and so on. However, if the guppy's tail fin, dorsal fin and even the caudal peduncle are found to be rotten, then it may be in the later stage of the disease. At this time, it is necessary to use some drugs such as potassium permanganate, but the concentration can not be too high. If necessary, we need to find a special doctor to treat guppies under their guidance.
