If the fish food is only after the expiration date, and there is no deterioration and mildew, it can also be fed. But spoiled fish food, whether expired or not, can not be fed again, otherwise it is easy to cause fish illness, serious will also lead to death. In addition, for some of the more delicate fish, expired fish food is best not to feed, so as not to cause indigestion.
1. Feed selection: Usually, artificial feed is used for feeding fish, and live bait can also be selected. Artificial feed is mostly pellets or flakes, if flakes are used, they need to be floated on the surface, suspended in the water or sunk to the bottom according to the water layer where the fish live. Live baits are mostly fish and worms, but they should be sterilized before feeding.
2. Feeding times: In order to allow the fish to grow rapidly, it is generally necessary to feed them 1-2 times a day. As the fish are relatively hunger-resistant, they can also be fed once every few days. However, although the fish fed in this way cannot die, they do not grow big, and they do not look very beautiful. The color is often not as bright as that fed frequently.
3. Feed dosage: Usually, you have to feed enough every time you feed the fish. For the fish, as long as you feed it, it will eat. However, when it is hungry, it eats something, and when it is full, it eats something. The state is also different. At the beginning, the fish grabs food quickly. As soon as it finds food, it swims quickly. After it is full, its appetite is not so strong.
4. Clean up the residual bait: It is inevitable to feed too many fish at ordinary times. At this time, there will be residual bait left at the bottom of the water. After being decomposed by microorganisms, harmful substances will be produced, and the water quality will be polluted. Therefore, it is necessary to clean up the residual bait in time. Every time the water is changed, the residual bait at the bottom should be discharged, so as to keep the water clean and hygienic.
