How much food to feed betta fish in a day should be adjusted according to their growth state. If they are in their infancy, they can be fed once in the morning and once in the evening, and twice a day. At this time, they need to grow vigorously and need more energy, so they need to be fed more at this time. If they are in adulthood, they can be fed once a day. At this time, they are fully developed, so they only need to be fed a little food to meet their daily needs. Generally, feed them food that can be eaten within 5 minutes at a time. Don't feed too much. If you feed too much, it will pollute the water quality.

Guppies are omnivorous fish, and there are many foods they can eat. They can be fed small animals such as small fish and shrimp, which are rich in protein and taste good, and are very popular among them. However, small animals will carry parasites and viruses, which will pollute the water quality if they are not cleaned before feeding. They can also feed them lettuce, spinach and other vegetables. Vegetables are rich in vitamins and cellulose, which are helpful for digestion, but these substances are particularly easy to digest and are not suitable for long-term consumption.

They can also eat artificial feed, which is a kind of feed prepared by mixing various substances and suitable for them to eat. It is rich in nutrients and has a long storage time. However, it contains preservatives, and feeding them frequently will cause harm to them. When raising at ordinary times, these foods can be matched and fed to them.
