Betta fish should generally be fed once or twice a day, with small portions each time to avoid overfeeding. A common recommendation is to feed them a small pinch or 2-4 pellets per feeding, spaced about 6-8 hours apart if feeding twice daily

. Feeding once a day is often sufficient and can keep your betta healthy, but some owners feed twice a day to keep the fish more stimulated

. It is important not to overfeed bettas because they will continue eating as long as food is available, which can lead to bloating, digestive issues, and water quality problems due to uneaten food decomposing

. Many experts suggest feeding only as much as the betta can eat in about 1-2 minutes and removing any leftover food promptly

. Some keepers recommend fasting the betta one day every 7-10 days to promote digestion and prevent constipation

. For baby bettas (fry), feeding should be more frequent, around 3-5 small meals per day

. In summary:

• Feed adult bettas once or twice daily with small amounts (2-4 pellets or equivalent).
• Space feedings 6-8 hours apart if feeding twice a day.
• Avoid overfeeding; feed only what the fish can consume in 1-2 minutes.
• Remove uneaten food quickly to maintain water quality.
• Consider fasting one day every week or so for digestive health.
• Feed baby bettas more frequently (3-5 times daily).

This approach balances betta nutrition, health, and tank cleanliness effectively
