Will They Need More Fin Room?
“I don’t know. They look like they all fit in there pretty comfortably right now,” Paul says unsurely.
Hannah nods her head firmly. “Exactly. Right now they do. If we add anymore they may not have enough room. Then that can lead to all kinds of problems.”
Paul frowns and rubs his jaw. “You may have a good point there, hon. I guess we should find out how many fish per gallon will fit comfortably here. Let’s use the same site we found that fish questions and answers post on.”
Paul pulls out his phone and goes to the site. There he finds the following:
What To Consider Before Adding Fish
Think about the types of pond fish you have and are getting. How large can they grow, how often do they breed, and how many little fishies can they have? Depending on these answers, you may have to get better filters and pumps. Flow rate, temperature, and even climate can also affect how many fish you can have.
How Big The Average Koi Fish Can Get
Koi can usually grow to somewhere between 2 and 3 feet long. We like to figure the average koi in your pond at anytime will probably be closer to 12 to 18 inches.

The Fish Per Gallon In A Pond Rule
For every 10 gallons of pond water, you can have 1 inch of fish. This leaves enough room for them to live comfortably and grow some. A 500-gal pond means you can have 50 inches of fish. 1,000 gallons means 100 inches of fish.
The Fish Per Square Foot Of Surface Area Rule
You can easily fit 1 inch of fish per square foot of surface area. So for 10 foot by 10-foot ponds you have about 100 square feet of surface area. This means you can fit about 100 inches of fish.
It’s best to not pack as many as you can into a pond. This makes sure they’re comfortable.
“We’ve all had that it’s-to-crowded-in-this-elevator moment. Let’s not do that for our fish,” Hanna says. Paul nods his head. “Yeah, it wouldn’t be great. This next part tells us more about why overcrowding isn’t good for fish.”
What Happens When You Over Stock Your Pond With Fish?
Your fish can get sick and/or have parasites.
With more fish comes more fish waste. That’ll put more pressure on your pond’s filters, and if they can’t handle it they’ll just recycle the dirty water.
This leads to algae, parasites, sickness, and a nasty pond.
More fish can lead to higher levels of ammonia in the water. This is dangerous during the summer. Ammonia levels rise in the summer heat. Add that to the higher levels with too many fish and they can die overnight.
“Well, how can we make sure this kind of thing doesn’t happen?” Paul scrolls down to find out.
