Ginrin Koi Mix

General information

Ginrin Koi is a scale variety that has iridescent scales that sparkle.There are many different color varieties of these fish, however, each pattern is unique, color patterns are like the koi’s fingerprint. Their maximum size is 3 inches. To keep these fish, water temperature should range from 36ºF to 90ºF and water pH should be between 6.8 and 7.2. With Koi it is very important to have a good filtration system and good water quality, ammonia levels should be zero or negligible and nitrate levels should be zero or negligible. The minimum pond size recommended is 1000 gallons with a 3 inches depth, the rule many aquarists use to determine good pond size is to add 10 gallons of water for every inch of fish. The pond should have gravel substrate, rocks and hardy plants.

This species is omnivorous. Koi can be fed with pellets and flakes. It is important to not overfeed Koi, special care must be taken in winter since these fish eat less and so food may remain in the pond uneaten and diminish the water quality.

Males are slimmer and have more pointy pectoral fins than females.

To breed this species, some shallow areas on the sides of the pond should be provided and water temperature should be around 68ºF. Breeding is usually more successful in late spring and early summer.

Koi originated in Japan. Doitsu Koi originated in Germany and was later imported to Japan where it was bred with many other Koi varieties originating new Koi varieties.

Since Koi live in ponds they are at risk from predators like eagles, cats and herons so, if needed, the pond should have a net on the surface.
