The Doitsu Kujaku High Quality Koi, Japan Strain is an impressive koi that shares qualities of the Kujaku Koi and the Doitsu Koi. The dark, net-like marking and the red/orange and white coloration of the Kujaku Koi is accentuated by the distinct arrangement of mirror-like scales of the Doitsu Koi. As a result, the Doitsu Kujaku Koi is bold in color and contrasting in scale pattern.

The Doitsu Kujaku Koi we offer are rated by breeders as AAA Grade Select – the highest rating these fish can receive. They are produced by some of the best brood stock in Asia. While Japanese koi can live longer than 200 years, their typical life span is 25 to 35 years. These high-quality Japanese strain koi are a product of years of professional breeding, and will turn your pond into a showcase of champions.

The ideal setup for Doitsu Kujaku Koi is a 1000+ gallon pond with a fine gravel substrate, rocks, and hardy plants. Because these koi savor plant roots and will dig to get to them, be sure to place large rocks around the base of plants to protect them. You will also need to provide adequate filtration to maintain proper water conditions.

Males are easily recognized by their concave anal section and occasionally by breeding spots on the head. Spawning may result in as many as 1,000 eggs, with fry emerging in approximately 4 to 7 days, depending on the water temperature. Feed fry small live foods or frozen daphnia for the first 3 to 4 weeks. At that time, gradually change their diet to crushed flake and pellet foods. Their color will emerge in about 3 to 12 weeks.

Feed Doitsu Kujaku Koi a quality pellet or flake food.
