Fish need to be fed every day. Under normal water quality conditions, you need to feed every day, but you can't feed too much or too little at one time. It is most suitable to ensure that the fish can finish it within half an hour. Fish are very resistant to hunger. They can survive without eating for a long time. However, if they are not fed for a long time, they can easily turn into old fish. Such fish will not grow big and look ugly. However, if it is a new fish tank, it should be fed once every 3-5 days before the water is well maintained to avoid the feces produced by the fish after eating, which will not be digested by the ecological environment of the fish tank, thus polluting the water quality and affecting the development of the fish.

Notes on raising fish:

1. Feed in an appropriate amount, not too much or too little. Too much will cause the fish to burst to death or digest. It will affect the ecological environment of the fish tank, and you should not feed it too little, otherwise the growth will be unhealthy. Under normal circumstances, feeding once a day is enough.

2. Change the water in the fish tank regularly and set up a filtration system to filter out fish feces and create a good ecological environment.

3. When raising fish, you should pay attention to the size of the fish tank. It should match the size of the fish and create enough living space. You should also pay attention to the density. If it is too close, the fish will be hypoxic.

4. The fish tank should not be placed with its back to the sun. It is best to have the sun shining on it, or prepare fish lamps to supplement the lighting.
