Kind of a Good Aquatic Environment for Raising Koi Fish
Koi fish are variations of the common carp (Cyprinus carpio). Typical Koi has a white or silver base color with red, gold, black, or orange patterns. It can grow up to 36 inches (91 cm) long. Unlike many pet fish that usually lives a maximum of 10 years, Koi can live for 30 up to 50 years if taken care properly and live in a conditioned environment for raising Koi fish.
Koi fish are generally easy to raise. They are peaceful and love to swim through every level of your pond. They swim at the surface and middle level. Besides, Koi look for food at the bottom in normal temperature and stay at the deeper level of your pond in colder temperature. They form schools between 5 to 15 individuals and swim together.
Considering their large size, the minimum tank size is 250 gallons for one adult fish. Therefore, a large school of Koi will require up to 1,000 gallons. The minimum depth of the pond should 6 feet.
It is best to set the environment for raising Koi fish as an outdoor water garden with various water plants. The best plants for your Koi pond are:
• Water hyacinth
• Water lilies
• Floating pondweed
• Duckweed, and many more
Besides another Koi fish, you can also put other breeds and non-fish creature in your pond, such as:
• Goldfish: The most popular mate—they have similar color and look beautiful when swimming together with Koi fish.
• Grass carp: A good companion as they trim down any plants that might be invasive.
• Largemouth Bass
• Striped Bass
• Amphibian: frog, salamanders, and newts
However, fish species such as Bluegill and small Cyprinids are not recommended to put inside the same tanks as Koi. Bluegill fish are Koi’s natural rival while small Cyprinids tend to be very anxious when they’re put into the same tank as large-sized fish.
Koi fish live best in the temperatures between 74-86 degrees Fahrenheit. To keep it from freezing during winter, set up a heating system.
A good baseline for tolerable oxygen level for Koi fish is 5.0 mg/L.
The pH level of Koi fish habitat should be around 6.8-8.2 and must be kept as stable as possible. Crushed limestone can help stabilize the pH level of your pond.
Although Koi fish will be okay without having any water flow, you can add a small stream or waterfall to decorate your pond.
Those are the tips for making an ideal environment for raising Koi fish. We hope that you can have fun while experimenting with your pond and keep your Koi healthy and happy.
