Feeding Frequency of Young Betta Fish
It is recommended to feed young betta fish twice a day. Young betta fish need to be fed more frequently because they grow fast and consume a lot of energy.

Feeding Amount and Food Types
Feeding Amount: Young betta fish can be fed about 10 pellets of feed per day, while adult fish can be fed about 20 pellets of feed per day.
Food Types: It is recommended to combine both plant-based and animal-based foods, mainly using feed supplemented with frozen bloodworms. For the feed, you can choose high-protein small pellets. The frozen bloodworms need to be thawed before feeding.
Precautions
The amount of each feeding should be moderate to avoid overfeeding which may lead to poor water quality. When feeding, you should control the speed of the fish and avoid putting too much feed into the water at one time. The food should be diversified, including dry fish food, frozen worms or live insects and so on.
