What should brocade carp pay attention to before entering the pool?
The transportation of koi is very simple, as long as you put it in a plastic bag for oxygen. Young or medium-sized fish can be transported by themselves, but large fish are often transported by operators. New fish are at great risk of carrying bacteria or parasites, and healthy fish will often be infected when they are not handled properly. Therefore, salt and antibiotics should be added to the water for transportation. Anchor head fish fleas and leeches are visible to the naked eye. If found, the wound must be removed and disinfected immediately. The most important thing is to adjust the water temperature. Generally speaking, the pool water of the operator is higher than that of the enthusiast. If the difference in water temperature is more than 5 ℃, fish are easy to catch cold.
