I have a 100 gal pond with 5 koi’s and 1 goldfish and they just love it and have NO problems.
One is a foot long and will not get bigger because of the space.
My koi’s range from 6 to 12.
My goldfish is 12 long.

Not nearly big enough for Koi. They can grow to 3 feet long. You have more than enough in there to allow your Koi to grow.

If you went strictly by the numbers, you would be overcrowded. Adult koi need 200 gallons and if you allowed each adult goldfish 40 gallons, you would be at 400 gallons, but as ponds tend to create a more healthy environment naturally, I want to tell you that I think what you have will be okay, but definitely don’t add anything else. Also, the rule for koi and goldfish is that the filter pump 10 times the water per hour as the size of the tank or pond, so, in actuality, you need a 2,000 gph filter. As your fish grow, you will need this extra power. Keep an eye on things. If they grow too large, you’ll need to think about expanding the pond or giving some away. Have fun with your pond! I’ve had several and have loved them all!
