Due to the ability to withstand sufficiently low temperatures shubunkin is suitable for keeping in ornamental ponds in greenhouses. Much more trouble, like all goldfish, it can bring him July heat. Aquarium is desirable spacious – at least 70 liters for two fish.
It is highly desirable artificial aeration of water and installation in the aquarium filter with a capacity of at least two and a half volumes per hour. Since the fish, like all their relatives, like to dig in the soil, raising a large amount of mud. The soil is desirable fine and medium fractional.
