1. Betta fish have high requirements on water quality. The water body should preferably have a moderate pH. It can be changed to 1/4 of the water a week and disinfected once every 30 days.

2. Betta fish do not require high oxygen, but the oxygen content in the water is the highest The good thing is that it is about 5mg/l, and the water temperature can be maintained between 24-27°C. When changing the water, pay attention to the temperature difference not too large, which will stimulate the betta and cause disease.

3. Proper light can be given to the betta in daily maintenance. If the light is too strong, it needs to be shaded appropriately to avoid excessive water temperature fluctuations.
