The Hikarimoyo group of Koi represents all multi colored metallic Koi. The most popular variety in this group is the Kujaku. It means "peacock" due to its Matsuba effect as seen on the Gin Matsuba, but now a Kohaku pattern is added, giving it a very rich and contrasting look. The Hariwake is a metallic white Koi, but now the Kohaku pattern is yellow. The Kohaku itself also comes in a metallic version which is named Sakura Ogon.
Koi are peaceful, social fish but can cause stress to other fishes because of their constant activity. They are compatible with similarly active and constantly feeding species like the Goldfish.
Koi grow large, up to about 3 feet or more, making an outdoor pond the only suitable habitat for them. Ponds should be at least 500 gallons in capacity, requiring larger sizes for bigger and more mature communities. For areas that freeze in the winter, pond depth should be at least 4 feet, and heaters must be provided to prevent the pond from completely freezing over. Water should be well oxygenated and efficiently filtered because of the fish’s tendency to excrete large amounts of waste. Outdoor ponds should be protected from predators like cats and raccoons, and from winged fish-eaters like herons, hawks, and eagles. Net or wire screens are recommended, so are shade trees to cover the pond from airborne predators. Floating plants like lotus and water cabbage, as well as bamboo canopies, are often used to provide shade and some protection for the fish especially in the summer.
