Daily care for betta fish mainly includes the following aspects:
Water quality management: Betta fish have relatively strict requirements for water quality. The suitable water temperature is 24-27 degrees Celsius, and the pH value should be maintained between 6.5 and 7.2. Neutral water is preferable for water acidity and alkalinity, and the dissolved oxygen content is best kept at 5mg/L. Water quality should be regularly tested to keep it clean and avoid sudden changes. It is recommended to change one-tenth of the water every day and completely change the water once a week. Make sure that the water does not contain chlorine to avoid harming the fish.

Feeding: Betta fish are omnivorous fish and need a certain amount of protein to stay healthy. You can choose commercial betta fish feed or live food such as bloodworms and earthworms. Feed once a day, but be careful not to overfeed to avoid food residues polluting the water quality.
Daily observation: Observe the health status of the fish frequently. If the fish is found to be sluggish, have a decreased appetite or exhibit abnormal behavior, immediately check the water quality of the fish tank and the health status of the fish and take measures in time.
Disease prevention: Clean the fish tank regularly, change the water quality, maintain a balanced diet for the fish and enhance the immunity of the fish. If any disease symptoms are found in the fish, consult a professional immediately.
Maintain a good environment: Ensure that the fish tank is placed in a well-ventilated place with appropriate light and avoid direct sunlight to prevent excessive increase in water temperature. At the same time, ensure the safety of the fish tank and avoid children's contact to prevent accidents.
In general, taking care of betta fish requires a certain amount of time and patience, but as long as you master some basic knowledge and skills, you can make betta fish live a healthy and happy life.
