Common carp are very hardy and can easily adapt to most conditions, though they prefer large bodies of slow or standing water and soft, vegetative sediments. They can typically be found in small schools, although larger carp often lead a solitary existence. They natively live in a temperate climate in fresh or brackish water with a 7.0 – 9.0 pH, and a temperature range of 35.0 – 85.0 °F.
