Kinh nghiệm PHÒNG TRỊ BỆNH cho cá BẢY MÀU

Hello everyone, my name is Nguyen Phat. Today I want to share with you how to treat and cure fish allergy. For me, I don't have a lot of experience in fish farming, but I have some experience that I learned from myself. In addition to catching fish when they are sick, I have some experience like this. When I find a fish that is sick, I will separate the sick fish and prepare a new pond to catch all the sick fish. I will remove all the water from the old pond and put in new water. After that, I will buy a lot of salt and throw it into the pond to make the water salty.
