Why did the guppy die all night?

Don't be sad, fish farming is like this, and things you can't predict often happen. The cause of death of guppies, water quality problems, sudden infectious diseases and so on. This happened when I started to raise fish from guppies. More than 120 kinds of beautiful guppies that have been raised for three years have basically vanished overnight. Finally, I found out the reason, that is, there was something wrong with the water quality, which made me feel uncomfortable for many days. When you have time to keep the water clean, save more water. If there are a lot of fish, it is no problem to filter and aerate. Changing water is also important. Don't let the fish catch a cold. If you catch a cold, it can easily kill fish. If you observe more at ordinary times, there will be fewer dead fish. Well, that's the answer for you. I hope you can know more about fish farming, and you will raise it well. I wish you success in raising fish.
