Rats and fish starve to death without feeding. Not only rats and fish, but all animals will starve to death if they are not fed for a long time. The purpose of feeding rats and fish is to replenish their energy and maintain their daily life. However, rats and fish are relatively hungry compared with other animals. Usually, they will not starve to death without feeding them for a month or two. But it is best to feed them at least once a day when raising them at home. Especially, the juvenile fish of rat fish are in the high-speed stage of growth and development, and are in urgent need of a lot of nutrition. Correct feeding habits can make them live better.

Rodents are also omnivorous animals, and they are not picky about the kinds of food they eat. They like to eat live bait with high protein, such as bread worms and water earthworms. These baits have high nutritional value, but their prices are more expensive than other foods, and they need to be sterilized and cleaned before feeding.

The vegetables that rats and fish often eat are spinach and lettuce, and fruits with high vitamin content such as bananas and apples are also their favorites. These plant feeds are rich in cellulose and vitamins, which are beneficial to the growth and development of rats and fish. If breeders have time, it is best to mix these two foods to feed them in normal feeding. If breeders don't have time, they can also choose to feed them with balanced nutrition, simple and convenient fish feed.
