Red-finned crucian carp is a typical tropical fish, which likes high temperature, so fish that can be mixed with them should also like the water environment with higher temperature. They are large and very strong. Therefore, it is not suitable for polyculture with other small fish. In addition, they usually move in the middle of the water body, and like to swim with their companions, often shuttling between stones and rockeries. Therefore, when feeding, some stones or rockeries can be placed in the water for them to play. It should be noted that do not beat the fish tank to frighten them, otherwise they are easy to jump around because of fright, or even hit to death. Generally speaking, red fin crucian carp is relatively easy to raise.
