for mixed culture of koi carp and goldfish. In fact, the choice of fish mixed with koi is very limited, because the size of koi is relatively large, the mixed culture of small fish will inevitably have problems, and as a wide temperature fish, the temperature requirements are not strict, so there is no need to use heating rods to control the temperature, and the mixed culture of tropical fish is not suitable. Although the size of goldfish is not as good as that of koi, it is not very small and will not be eaten by it, so it can barely be mixed.
should be paid attention to in polyculture of koi carp? 1. Close body shape: polyculture should first pay attention to the body shape of fish. Fish of similar size are less difficult to mix, because they are similar in size and do not want to eat each other. As long as they are gentle and not easy to fight, they are safer to mix. If you bite every day, it will also cause some losses.
2. Similar habits: Fish raised together should also have similar habits. For example, their requirements for water temperature and pH, if they are all fish that like weak acid or weak alkaline water quality, then it is more convenient to adjust the water quality. If one likes weak acidity and the other likes weak alkalinity, no matter how to adjust, there will always be one party who can not raise the state.
3. The fish tank should be big: In order to ensure that the fish will not fight when they are mixed, we must prepare enough space for activities, otherwise some fish have a sense of territory, especially during the estrus period, if it is too crowded, it is easy to fight.
