Parrot fish don't need to add salt every time they change water, because they belong to freshwater fish. If salt is added every time they change water, the concentration of salt in water will increase, which is not only not good for their health, but also affects their normal development.

Although salt is not needed in normal breeding, when fish are sick, breeders need to add salt to them. Because adding salt can promote the metabolism of fish, it can also kill some bacteria in water and promote them to heal faster. In addition, if breeders want to add salt at ordinary times, it is best to choose to add some salt regularly. For example, salt can be added once every 1-2 weeks, and the concentration of salt should be controlled between 0.3% and 0.5% each time.

It is better to put salt in raising parrot fish. Especially when parrot fish is sick, it is best to put salt at this time. Because salt can sterilize, it can also improve the metabolism of parrot fish, speed up their recovery, and be more conducive to the recovery of the disease. In the usual feeding process, salt can also be put regularly. This can inhibit the growth of bacteria and reduce the risk of parrot fish getting sick.

Although it is better to put salt in raising parrot fish, breeders should also pay attention to not putting too much salt. If the concentration of salt is too high, it will not only affect their normal life, but also cause harm to their health.
