How many Koi can one can safely keep? -William

William,
The standard that most people go by is this:
One Koi for every 150 gallons of water in a pond, or 1:150.

150 gallons of water per Koi will give them plenty of room to swim around and plenty of space to grow out.

Some people go much higher than 150 gallons per Koi, some go up to 1,000, 1,500 or 5,000!

Many hobbiests do get concered if they have 22 or 23 Koi in a 3,000 gallon pond. They don't need to worry, it only lowers the ratio by a few gallons.

The amount of filtration that you have for your pond is far more important than a gallon ratio. Being underfiltered is far worse than being overstocked.
