Color enhancers, like spirulina, carotene and marigold extract are added to foods to enhance the colors on Koi & Comets..
During the Fall and early Spring when water temperatures are low, fish should be fed a food high in carbohydrates and low in protein. As the digestive systems are slower in cold water, these low protein foods pass through the fish more quickly, reducing the risk of the food lingering in the gut, causing severe problems.
When water temperatures drop, the fish become dormant. They do not eat or swim, and their respiration slows down. You must keep a small hole in the ice to keep the pond from freezing over using a small aerator and /or deicing unit. Always keep the air compressor (aerator) above the water level to avoid back flow possibilities. If it needs to be installed low, a one way valve to prevent water from suctioning (back flow) into motor when off would prove to be beneficial. Cover the electric motor from the elements to avoid wear and tear issues and possible water getting to electric motor.

Feeding Goldfish & Koi
Goldfish and Koi are bottom feeders. They can be trained to come and eat from the surface by using floating food in either pellet or stick form. These fish benefit from a diet with a protein level of 30-40%. Check the main ingredient in your fish food. The protein in the food should from an animal (like fish) rather than a plant. The better foods use fish meal or anchovy as their protein base. Making them more expensive.
