What should I do if Thai betta burns its tail? It's getting worse.

If this happens, please put a small amount of big salt (big salt is also called coarse salt, not when we are cooking) and observe for two days. If there is no improvement, you can buy gentamicin injection and sprinkle a small amount into the water. If this fish unfortunately doesn't come, you should sum up your experience. 1, you'd better change your container to glass. You should have replaceable water at any time, commonly known as making water. Betta likes acidic water environment. You can buy some elemene leaves and soak them in clear water for a week before changing the water. Similarly, you can also buy a slippery piece of wood, boil it in boiling water for disinfection, and then soak it in clean water to change water. Betta's life span is not very long, and it can survive in anoxic environment, but you should pay attention to water quality and oxygen and change to a bigger house. 20*20cm glass jars are recommended. You should belong to Xiao Banyue. It is recommended to buy ordinary betta fish. Although the tail is not as good as other models, the general fighting fish looks good and lively.

The above is personal experience, I hope I can help you:)
