Cooked rice can be fed to fish. The main component of rice is starch, which is not very helpful to the growth of fish, but basically there is no harm, so it is ok to feed it once in a while, and it cannot be used as a staple food, otherwise the fish will be malnourished and affect its development. Usually, special fish food should be selected for feeding fish. According to the different feeding habits of fish, the types of fish food selected are also different.

1. Feed selection: There are many kinds of ornamental fish, and their feeding habits are different. Some fish like meat, while others like vegetarianism. According to their preferences, special food needs to be prepared. For example, carnivorous fish need to be fed with some small fish and shrimp, while herbivorous fish need to be fed with algae, and omnivorous fish eat both.

2. Feeding times: Usually, fish should be fed three times a day, but if it is a larger fish, it is ok to feed once a day. Because of the fast digestion speed of fish, they will have appetite almost whenever they are fed, but it is easy to break the water if they are fed too much, so they must control their appetite and finish eating within 3-5 minutes every time they are fed.

3. Precautions: After each feeding, if there is residual bait, it should be cleaned up in time to avoid polluting the water body. When changing water at ordinary times, food and feces falling under the water should also be discharged, so as to better maintain the water quality.
