In nature, it is natural for big fish to eat small fish, and some fish will even eat their own children. So usually mixed fish, the best choice is relatively close to the species, if the difference is too large, small fish are eaten only sooner or later. In addition, we should ensure that the habits of mixed fish are similar, so that there will be no problems in raising them together.
1, isolation feeding: To avoid big fish eating small fish, the simplest way is to carry out isolation. They can be placed in different tanks, or some isolation measures can be installed in the tank, so that they can not see each other, so that the big fish can not eat the small fish.
2. Provide shelter: There is also the phenomenon of big fish eating small fish in the wild, and the reason why small fish have not died out is that they can find some places to escape, and the space in the fish tank is narrow, so they often have no way to avoid. But as long as a shelter is provided to ensure that the big fish can not enter, so that the small fish can swim inside naturally and safely.
3. Adequate feeding: It is necessary to provide more adequate feeding for fish farming at ordinary times. Fish that are full often do not have too strong aggression, so they must be adequately fed. Of course, they cannot be fed too much, otherwise it will easily lead to fish mixed with enteritis.
