Fish for Ponds

There are few things as rewarding and enjoyable as creating and then caring for a pond of fish filled with your favorite fish. However, there is a certain amount of knowledge, maintenance, and care involved in order to have a beautiful new fish pond with healthy, thriving fish.

The Best Types of Pond Fish

The Goldfish

Small members of the carp family, the many varieties of goldfish are rather hardy fish that fare well in different types of freshwater, which is why they make the excellent starter fish for the new pond enthusiast.

To keep your goldfish healthy, your pond’s water temperature should be kept between 40 and 105 degrees Fahrenheit, although they do tend to do best at the lower end of the temperature spectrum. The water should be kept at a Ph level of 6.0 to 8.0, and these low-maintenance fish will do best in ponds with a high level of oxygen.

Koi

Koi, which are Japanese carps, are among the very most popular pond fish due to their sheer beauty, wonderful personalities, and also because they are relatively easy to care for and enjoy a long life span. It’s not unusual for a well cared for Koi to live past 30 to 35 years.

Koi fish will thrive in water that’s kept very clean and clear, and chlorinated water is extremely dangerous for the Koi. The optimum fish pond Ph level is between 6.5 and 9.0, and 50 degrees Fahrenheit is the best temperature for this type of fish.

As they are rather social fish, Koi ponds should contain a minimum of three fish with at least 500 to 1,000 gallons of water that is three feet deep. Since Koi can grow up to three feet long, the bigger the pond, the better, and to keep your fish safe from predators such as raccoons or cats, keep a net covering the top of the pond. You may also want to invest in a protein skimmer to keep the water as clean as possible and free from waste, and a pump to increase the water’s oxygen level, allowing you to add more fish, but taking care not to overstock.

Some of the lesser known, or less common types of pond fish include the Black Moor, the Ranchu, the Lionhead, and the Bubble-eye Goldfish. Pond Comets, Fantails, and Orandas are popular choices, however, it’s important to not mix Fantails and Orandas with either Pond Comets or Koi due to the aggressiveness of the latter two.

And, while there are several different varieties of interesting fish suitable for a garden pond, always do plenty of research first to ensure you aren’t adding fish that aren’t compatible with one another as the food chain is a rather important point to take into consideration. The same is also true for the type of aquatic plants you add to your pond.

Tips for Fish Pond Care and Maintenance

  • Cleaning and changing the water: It’s recommended to change 20% of a pond’s water twice each and every week, and a long-handled, wide net is essential for keeping the water clean, and for removing debris from the bottom of the pond.
  • Feeding: A good rule of thumb to follow, especially for Goldfish ponds, is to only feed the fish as much as they can eat within five minutes time, and remove the any uneaten food with a net after 10 minutes.
  • Water temperature: When starting a new pond, timing is of the utmost importance in regards to temperature. Never add fish to a pond before the spring, or generally around mid-May, depending on where you live. While the most common pond fish can indeed withstand colder temperatures, the initial shock of cold water can actually be fatal to a fish if it hasn’t had time to acclimate itself to its surroundings.
