Betta fish mainly eat the following types of fish feed:
Artificial Feed: Betta fish can eat artificial feed specially formulated for tropical fish. These feeds usually contain a variety of nutrients and can meet the basic nutritional needs of betta fish. Common brands include Hikari Bio-Gold (which can enhance the red color of fish), brine shrimp eggs and so on. These feeds are rich in carotenoids, which help make the body color of betta fish more vivid.

Live Bait: Betta fish also like to eat live bait, such as brine shrimp, tubifex worms, water fleas and so on. These live baits can not only provide rich protein and other nutrients for betta fish, but also increase their activity level and promote their health.
Vegetable Feed: Betta fish also like to eat some vegetable feeds, such as algae, aquatic plants and so on. These vegetable feeds can not only provide necessary vitamins and minerals, but also help betta fish with digestion.
Suggestions on the Rearing Environment and Management of Betta Fish:
Water Quality Management: Betta fish have relatively high requirements for water quality. The suitable water temperature is between 22 - 28 °C, and the pH value is between 6.5 - 7.5. Regularly change the water to keep the water quality clean. Avoid using chemical cleaners to prevent harm to betta fish.
Lighting: Betta fish need appropriate lighting, but avoid direct sunlight. Appropriate lighting helps to make the body color of betta fish more vivid.
Environmental Arrangement: Place some aquatic plants and stones in the fish tank to provide hiding places and playing space for betta fish. Meanwhile, some plankton models can be placed to attract the attention of betta fish and promote their activities.
Through reasonable feed selection and good management of the rearing environment, we can ensure that betta fish grow up healthily and display their vivid body colors.
