How To Care For Koi Fish

Koi fish can survive in cold and tropical climates, but their ideal temperature is between 65-75 degrees Fahrenheit. The pH level in their tank should be between 7-9.  They should not be kept in direct sunlight and proper water ventilation is vital, so they should have a high-volume filter.

Their tank should have a smooth, muddy or fine gravel substrate. They will tend to dig through the substrate, so live plants might not always work well in their enclosure.
