There could be several reasons why your betta fish is not eating, even though you have tried various types of food and maintain a proper water environment. Here are a few things to consider:

1. Stress: Moving to a new environment can be stressful for a betta fish. If your betta was recently introduced to your tank, it may take time for it to adjust and feel comfortable enough to eat. Try to minimize any additional stressors in the environment, such as sudden changes in lighting, excessive noise, or other tank mates that may be aggressive.

2. Illness: Betta fish can be susceptible to various diseases and illnesses that can affect their appetite. Observe your betta closely for any signs of illness, such as lethargy, changes in color or behavior, or physical abnormalities. If you suspect your betta may be ill, it's best to consult a veterinarian or experienced aquarist for proper diagnosis and treatment.

3. Food Preferences: Betta fish may have specific food preferences. While you have mentioned trying different types of food, including bloodworms, it's possible that your betta may prefer other types of food. Try offering a variety of high-quality betta foods, including live or frozen brine shrimp, daphnia, or micro worms, to see if your betta shows more interest.

4. Water Parameters: Even if you maintain the water temperature, you should also check other water parameters such as pH, ammonia, nitrite, and nitrate levels. Betta fish are sensitive to water quality, and fluctuations or high levels of certain chemicals can affect their appetite. Use a water testing kit to monitor these parameters and make adjustments if necessary.

5. Competition for Food: If you have other tank mates, there might be competition for food. In this case, it's important to make sure that your betta fish is getting enough food. You could try feeding it in a separate container or at a different time of day to avoid competition.

6. Dental issues: dental issues or infections could be causing the betta fish to lose its appetite. Consider providing softer food options and monitoring the fish's behavior and oral health.

Remember that bettas may sometimes go through periods of reduced appetite, especially if they are new to the environment or if there are changes in their surroundings. If your betta continues to not eat after trying the above suggestions and ensuring proper water conditions, it's best to seek advice from an expert or veterinarian to rule out any underlying health issues.
