The Koi Pond

Introduction

If you’re thinking of adding a new fish species to your koi pond, look no further than the sterlet. Although not as popular as koi, this fish can make a great addition to any pond. Not only are sterlet visually stunning with their unique diamond-shaped sturgeon body, but they also serve a practical purpose in your pond ecosystem. In this guide, we’ll go over everything you need to know about adding sterlet to your koi pond, including their behavior, diet, ideal water conditions, and more.

Behavior and Compatibility

Sterlet are generally peaceful fish that can coexist well with koi, goldfish, and other pond fish. However, they can be shy and may take some time to acclimate to their new environment. It’s important to provide ample hiding places for them, such as caves or plants. Sterlet are bottom-dwelling fish that prefer cooler temperatures and slow-moving water. They also appreciate a mix of gravel and sand substrate to burrow in.

Diet

Sterlet are omnivores and will eat a variety of foods, including commercial pellets, worms, insects, and small crustaceans. It’s important to provide a varied diet to keep them healthy and happy. Additionally, you should avoid overfeeding your sterlet as they have a slower metabolism than koi. Feed small amounts multiple times throughout the day instead of one large feeding.

Water Conditions

Sterlet require a well-established and cycled pond before introduction. Make sure the water parameters are suitable for both koi and sterlet, including pH levels between 7.0-8.5, ammonia and nitrite levels at 0 ppm, and nitrate levels below 40 ppm. Sterlet prefer cooler water temperatures between 50-68°F and a moderate flow rate. Be sure to provide plenty of oxygenation to the pond with fountains, waterfalls, or air stones.

Maintenance

Maintaining a healthy pond environment is crucial for the health of your sterlet and other fish. Regular water testing and partial water changes should be done to keep the water parameters in check. Additionally, cleaning the pond and filters regularly will help prevent any buildup of debris or harmful bacteria. Lastly, be mindful of any predators that may be attracted to your pond, such as raccoons or herons.

Conclusion

Adding sterlet to your koi pond can bring a new level of diversity to your pond’s ecosystem. With proper care and attention, sterlet can thrive and make a great addition to any pond. Just remember to acclimate them gradually and provide ample hiding places and a varied diet. Follow the guidelines outlined in this guide to ensure your sterlet and other pond fish live a happy and healthy life.
