The fish tank of mixed culture must be large, because animals will have a certain sense of territory, if the fish tank is particularly small, it is easy to trigger all kinds of conflicts, causing them to attack and bite each other, not only will they be injured, but also may die. Larger tanks, on the other hand, are less likely to be injured or killed when faced with such a situation.
In order to let the small fish and shrimp in the fish tank have a place to hide, it is best to plant some aquatic plants in the tank. Common aquatic plants are mosses, which can play a good role in shading, while other large-leaved aquatic plants are often not very practical. It should be noted that the cultivation of aquatic plants requires aquatic mud, which can not be paved with ordinary sand.
The choice of species is also very important in polyculture of fish and shrimp. Simply speaking, you cannot raise too big fish, and you cannot raise too small shrimp, because shrimp rarely have the opportunity to eat fish. They tend to eat fish eggs, and it is more common for fish to eat shrimp. In order to avoid this, you cannot allow fish and shrimp to have too big a difference in posture.
In order to make the fish and shrimp breathe better, be sure to oxygenate the tank regularly. Usually, it can be oxygenated for 2-4 hours a day, and if there is still a phenomenon of anoxic floating head, it will be added for 2 hours. Generally, the more organisms in the tank, the longer the oxygenation time, especially in the case of plants such as aquatic plants.
