The simplest way to prevent big fish from eating small fish is to isolate them. The same fish tank can also be isolated, as long as the preparation of a special isolation net, to ensure that the mesh is small enough, will not let the fish come and go. It should be noted that the isolated space should be reserved for the big fish so that it can carry out activities.
The reason why big fish eat small fish is often because they are hungry. If they are fed adequately at ordinary times, this situation can also be avoided. Usually two to three times a day to feed, according to the feeding habits of the fish, choose the right feed, each time to feed seven or eight points full, if fed, it is easy to cause the fish to suffer from enteritis.
Big fish in the wild will also chase small fish, and small fish can survive, generally rely on a variety of shelter, if there are aquatic plants in the fish tank, often can let small fish avoid the attack of big fish, if you can not plant aquatic plants, can also provide some shelter, when attacked. Small fish will swim inside to avoid being eaten.
Generally, big fish and small fish should not be raised together. If it is necessary to raise them together, the number of the same kind of small fish can be more. In this way, when the small fish swim in a group, it can also form a certain deterrent force, thus avoiding being eaten by the big fish.
