Below is a detailed guide to feeding frequency for betta fish, with recommendations based on different growth stages and rearing conditions:

I. Regular Feeding Frequency
Adult Bettas
Feed once daily (preferably between 9–11 AM).
Control portions to 5–10 pellets of specialized food per feeding (amount should be consumed within 2 minutes).
Juvenile Bettas
Feed twice daily (once in the morning and once by 3 PM).
2–5 pellets per feeding, with food fully consumed within 10 minutes.
II. Adjustments for Special Periods
Breeding Fish
Feed small portions 3–4 times daily.
Increase the proportion of live food (such as water fleas).
Low-Temperature Winter Periods
Feed once every 3–4 days.
Stop feeding entirely when water temperature drops below 20°C.
III. Key Considerations
Feeding Observation: If food remains uneaten after 5 minutes, reduce portion sizes.
Water Quality Management: Remove leftover food promptly and replace 1/3 of the water weekly.
Avoid These Times: Never feed at night (increases risk of oxygen depletion).
Note: Reduce feeding amounts by 30% on rainy days. If white feces appear, stop feeding and monitor closely. For specialized food, choose products containing fish meal or shrimp meal.
