Buying Guide: How to Choose the Best Pond Fish
When I first started my pond, I thought any fish would do, but I quickly learned that choosing the right species is what makes a pond thrive instead of just survive. Your pond is a unique ecosystem, and the fish you select need to be a good fit for your specific setup, climate, and goals. Let me walk you through the main things I consider before adding any new fish to my water garden.
The first and most critical factor is your climate and pond depth. If you live in an area with cold winters, you need fish that can handle it. Many common pond fish are hardy, but they still require a pond deep enough that it won’t freeze solid. A general rule I follow is to have a section at least 18 to 24 inches deep to provide a safe haven where the water remains liquid. For koi, I prefer even deeper areas. If your pond is shallow, you might need to bring fish indoors for the winter or stick exclusively to very cold-tolerant species.
Next, think about the adult size of the fish. This is where many beginners, including myself, make mistakes. That tiny, cute koi or goldfish from the store will grow, and it will grow a lot. Overcrowding is a fast track to poor water quality, stressed fish, and constant health problems. I always research the full-grown size of a species and plan my stocking levels conservatively. A good starting point is to allow for 10 to 20 gallons of water per inch of fish, but always err on the side of more space.
You also need to consider the fish’s behavior and diet. Are they peaceful or aggressive? Do they dig up plants? Some fish are fantastic algae-eaters, like the common pleco, but they can become enormous and may bother other fish. Others, like koi, are known to be curious and can uproot delicate plants. I like to create a balanced community where the fish have compatible temperaments. I also make sure I understand what they eat; while many fish will eat standard pond pellets, some have specialized needs.
Finally, don’t forget about water quality and filtration. More fish means more waste. A robust filtration system is non-negotiable for keeping the water clear and the fish healthy. The types of best pond fish you choose directly impact your filter’s workload. Koi, for instance, produce a significant amount of waste and require a much more powerful filter than a school of smaller shubunkin goldfish. I always match my filtration capacity to the bio-load my fish will create, and I never skip on a good quality pump and filter. Getting this right from the start saves so much trouble down the line.
FAQ
How many fish can I put in my pond?
This is probably the most common question I get, and it’s not a one-size-fits-all answer. A general guideline I use is the “one inch of fish per ten gallons of water” rule. So, if you have a 500-gallon pond, you could theoretically have 50 inches of fish. However, I treat this as an absolute maximum, not a target. I always stock less than this to account for growth and to keep the water quality pristine. Overcrowding is the primary cause of algae blooms and sick fish, so when in doubt, put fewer fish in.
Can koi and goldfish live together?
Yes, they absolutely can! I have kept them together for years. They are both peaceful, hardy members of the carp family and have similar water quality and dietary needs. The main thing to watch for is the size difference. A very large koi might see a very small fancy goldfish as food, so I make sure my goldfish are large enough that they aren’t seen as a snack. Also, remember that koi grow much larger and will eventually need more space than a comparable number of goldfish.
What should I feed my pond fish?
I feed my fish a high-quality floating pellet that is specifically formulated for pond fish or koi. The key is to choose a food that matches the water temperature. In warmer summer months, I use a growth or staple diet that is high in protein. When the water cools down in the fall and spring, I switch to a wheat-germ based food that is easier for them to digest in cooler temperatures. Most importantly, I only feed them what they can consume in about five minutes to avoid leftover food spoiling the water.
Do I need a heater for my pond in the winter?
For the fish themselves, usually not. If your pond is deep enough (as I mentioned in the buying guide), hardy fish like koi and goldfish will go into a state of torpor at the bottom and be just fine. However, I always use a pond de-icer or a floating heater. This isn’t to heat the pond, but to keep a small area of the surface from freezing over. This opening is crucial for allowing harmful gases to escape and oxygen to enter, which is far more important for their survival than warming the water.
How do I introduce new fish to my pond?
I never just dump new fish in! This is a surefire way to shock and potentially kill them. The process I follow is called acclimation. First, I float the sealed bag they came in on the pond’s surface for about 15-20 minutes so the water temperatures can equalize. Then, I slowly add small amounts of my pond water to their bag over the next 15-20 minutes. Finally, I gently net the fish out of the bag and release them into the pond, being careful not to pour the water from the pet store into my pond, as it could contain contaminants. Taking this extra time reduces stress and gives them the best start in their new home.
