1. Animal feed: Thai betta fish are omnivorous fish. They can eat most foods, but their favorite is animal feed. When artificially raised, they can be fed with some bumper shrimp, red worms, earthworms, water fleas, silk earthworms, yellow mealworms, lean meat and so on. These foods contain more protein, which can meet their nutritional needs.

2. Plant feed: Although they don't like plant feed very much, it is best for breeders to feed them some, so as to ensure their nutritional balance. Plant feeds suitable for them include algae, aquatic plants, tender leaves of vegetables, broken fruits and so on.

3. Synthetic feed: When Thai betta fish reach adulthood, breeders can also feed them some synthetic feed. The nutrients of these feeds are comprehensive, which are made according to the characteristics of fish, and are not easy to pollute the water quality, so they are very suitable for feeding Thai betta fish.

1. Feeding amount: The feeding amount of Thai betta is different at different stages. If it is a juvenile Thai betta, the feeding amount can generally be finished within 5 minutes. If it is an adult Thai betta fish, it is best to eat it in 10 minutes at a time.

2. Feeding frequency: The feeding frequency of Thai betta fish should also be determined according to their growth stage. Under normal circumstances, young Thai betta fish can be fed 3-4 times a day. When they are adults, they can choose to feed them 1-2 times a day.
