How Many Fish Is Too Many In My Pond?

You just finished building this awesome pond and one of the first things you want to do is add some koi and other beautiful pond fish. These fish will soon turn into pets with names and are fun to watch, bringing a lot of enjoyment to your day. While koi and other fish can be beautiful additions to your pond, they can also cause problems if you don’t have the proper pond set up or add too many.

For those of you with brand new ponds and want to add fish, do not add all of them at once. Adding 1-3 fish at a time gives your pond’s eco-system time to adjust and get established. Then continue to add more, making any proper adjustments as time goes on.

The general rule for your pond and fish, especially in the first year is; 1 inch of fish per one square foot of water. Or in other words, about 1 inch of fish per 10 gallons of water.

Remember, fish grow and multiply over time.

Keep in mind that your pond set-up plays a huge role into the overall health of your fish. Pumps, plants, proper feeding schedules, routine water testing, aeration and biological filters all play important roles into having happy healthy pond fish.

So, before adding more koi and other fish into your pond, make sure you have enough space and a proper setup, so they can have a happy healthy home that both you and your fish can enjoy!
