Water's high specific heat capacity is ideal for this pond
Detailed Description
The high heat capacity of water has a great deal to do with regulating extremes in the environment. For instance, our fish in the pond are indeed happy because the heat capacity of the water in the pond means the temperature of the water will stay relatively the same from day to night. Fish don't have to worry about either turning on the air conditioner or putting on their woolen flipper gloves.
