Are there any fish-raising experts who can tell me how to use the fish medicine [Malachite Green]?

Malachite green is toxic and can cause cancer! It is not recommended to use it, and most foreign countries have banned it.

Go to a fish shop and ask them to sell you furacillin or methylene blue. Add water until it turns slightly yellow or blue and soak it for a day or two and it will generally be gone. You need to add oxygen and keep the water temperature within the appropriate range. . . . .

In fact, it doesn't matter if you don't use medicine. Tail rot is a matter of water quality. Change the water, add oxygen, wash the filter cotton, filter more substances, ensure that nitrifying bacteria decompose harmful ammonia nitrogen substances, add a little salt, wait for a day or two, if you can survive it, you'll survive, if not, you'll die... Haha...
