After changing the water for parrot fish, you need to wait for a while before feeding them. It is generally recommended to start feeding on the day after the water change. This is because after the water change, parrot fish need time to adapt to the new water quality and environmental changes. Feeding too early may lead to indigestion or other health problems.

Specific Feeding Time and Precautions after Water Change
Waiting Time: After changing the water, it is advisable to wait at least one day before starting to feed, ensuring that the parrot fish have adapted to the new water quality and environment.
Water Quality Management: Keeping the water clean and stable is the key to raising parrot fish. Regularly change part of the water and clean the filtration equipment to ensure good water quality.
Water Temperature Control: The suitable water temperature for parrot fish is generally between 25°C - 28°C. When changing the water, make sure the temperature difference between the new water and the old water does not exceed 2°C.
Proper Feeding: Select high - quality feed and determine the appropriate feeding amount according to the size and activity level of the parrot fish. Avoid over - feeding, which can cause water quality deterioration.
Breeding Environment and Nutritional Requirements of Parrot Fish
Environment: Provide a quiet environment to avoid scaring the fish. Ensure 2 - 3 hours of light exposure per day and make sure there is sufficient oxygen.
Nutrition: Do not rely solely on pellet feed. Mix it with other foods to ensure a balanced diet. The size of the pellets should be appropriate to avoid difficulty in swallowing.
By following these measures, it can be ensured that parrot fish can smoothly adapt to the new environment after the water change and grow healthily.
