Under normal feeding conditions, the water in which guppy lives generally does not need salt. Because guppy belongs to freshwater fish, it doesn't like to live in high concentration water environment. If salt is added directly to the water where guppies grow, it may cause discomfort or other discomfort. If the salt concentration in the water where guppies live is too high, they may dehydrate.

But it's not that salt can't be added to peacock water. When they get sick, breeders still need to add some crude salt, which can play a role in sterilization and speed up their recovery.

As mentioned above, guppy can be treated by putting salt after getting sick, but it is also necessary to pay attention to the method of putting salt. The first is the kind of salt, like household salt, which is not suitable for guppy. Breeders should choose coarse salt or sea salt, so as not to affect the health of guppy. The second is the concentration of salt. Guppies are not suitable for growing in an environment with high salt concentration, and breeders need to control the concentration of salt between 0.3%. Finally, we should pay attention to the use of methods. Generally, in the early stage of guppy's illness, the effect of adding salt is better. But in the later stage, the effect of using salt is not very good.
