According to search results, the feeding frequency for betta fish needs to be adjusted based on their age, health status, and environment. Here are specific recommendations:
Adult Betta Fish
Feed them once a day or once every two days.
Control the amount per feeding to what they can finish within 10 minutes, approximately 10-20 pellets.
Juvenile Betta Fish
They require more frequent feeding, with 2-3 times a day recommended.
Reduce the amount per feeding—around 10 pellets per meal during the juvenile stage.
Important Notes
Avoid overfeeding, as it can lead to poor water quality or health issues for the fish.
Provide a varied diet, including specialized betta food, frozen insects, or live insects.
Maintain clean water by changing it regularly.
If you’re short on time, betta fish are highly tolerant of hunger and won’t starve if fed once a week. However, doing this long-term will affect their activity levels and coloration.
