Betta fish need to be fed once a day. Betta fish are tropical fish with a relatively fast metabolism. They need to consume food regularly to maintain their health and vitality. Feeding them once a day can meet their nutritional needs and ensure good growth and development. Moreover, betta fish have a small appetite. Each time, no more than 10 pellets of fish food should be given. It's enough to let the fish be about 70% full to avoid overfeeding, which can lead to indigestion and water quality deterioration.
The food requirements of betta fish vary at different growth stages and in different seasons. For example, during the fry stage, betta fish need more protein and nutrients to support their rapid growth. In winter, due to the decrease in water temperature, the appetite and activity level of betta fish will decline. At this time, the frequency and amount of feeding can be appropriately reduced. In addition, there are various food options for betta fish. They can be fed with specialized fish food, worms, or live bait such as mosquito larvae. However, it's important to control the feeding amount to avoid overfeeding.
