Koi are the fish that are most commonly associated with garden ponds. They have been raised in the Orient for centuries, with the earliest colored varieties dating back two hundred years. Due to the size of these fish they should be kept in large sized ponds, especially if you plan on keeping more than a few fish. Koi have strong mouths, and like to dig in the substrate. Therefore, only tough leafed plants should be planted in the pond, and be sure to protect the roots and soil of your pots with a layer of gravel.

Feeding Habits Koi will eat all types of food. Live, frozen, freeze-dried, and prepared foods will be devoured without hesitation. Make sure to include plenty of plant material in their diet. Most prepared koi foods include plant material, but occasionally feeding spirulina flakes, wheat germ pellets, or even chopped, frozen spinach would be a good idea.
Compatibility Koi are generally peaceful. They may, however, pick on slow moving fish such as fancy goldfish. Since they are cool water fish, they generally should not be housed in an aquarium with Tropical Fish.
Overwintering Koi can be overwintered in the pond in most areas of the country if the water is at least 3 feet deep. They are not as cold tolerant as the goldfish, so keeping them indoors would be advised in very cold climates. Koi can be kept in a large aquarium set-up in a cool basement or garage until the spring, then returned to the pond.
Additional Comments There are many different color variations of koi available. Their average life span is 60 years.
