Pond Fish

The best fish for your pond depend on its size, depth, and purpose. Popular options include koi for their vibrant colors and graceful swimming, goldfish for smaller ponds, plecostomus for algae control, and catfish for bottom-dwelling clean-up. Our team can help you select fish that match your pond’s needs and climate.

A general rule is to allow one inch of fish per 10 gallons of water. Overcrowding can lead to poor water quality and stressed fish. For larger species like koi, ensure there’s enough space to accommodate their growth. Our staff can help calculate the appropriate stocking level for your pond.

Yes, koi and goldfish are compatible and often thrive together in the same pond. Both species are hardy, share similar water quality needs, and coexist peacefully. Just ensure your pond is large enough to accommodate both species.

Yes, while pond fish can find natural food like algae and insects, supplemental feeding ensures they receive proper nutrition. Feed your fish once or twice a day, but only what they can eat within a few minutes to avoid overfeeding. Reduce feeding in colder months as fish metabolism slows.

To keep your fish healthy:

• Maintain good water quality with proper filtration and aeration.

• Monitor water temperature and pH levels regularly.

• Avoid overcrowding your pond.

• Provide a balanced diet and remove uneaten food promptly.

• Perform regular pond maintenance to reduce debris and algae.

Yes, most pond fish like koi and goldfish can survive Oklahoma winters if your pond is deep enough (at least 18-24 inches) to prevent freezing. Adding an aerator or pond de-icer ensures gas exchange and prevents ice from sealing the surface entirely.

Acclimating new fish is crucial to reduce stress and prevent shock. Float the bag with the fish in your pond for 20-30 minutes to equalize temperatures. Gradually add small amounts of pond water to the bag before releasing the fish.

Common signs of illness include lethargy, loss of appetite, or visible spots or damage on their bodies. If your fish appear sick:

• Check water quality for imbalances in pH, ammonia, or nitrate levels.

• Quarantine the affected fish if possible.

• Contact our team for advice on treatments, such as water conditioners or fish medications.

Yes, adding fish to an established pond is a great way to enhance its ecosystem and beauty. Ensure your pond has adequate space, filtration, and oxygenation to support additional fish. Gradually introduce new fish to prevent stress and maintain balance.

Plecostomus, tilapia, and certain types of goldfish are excellent algae-eaters. Adding these fish to your pond helps naturally manage algae growth, keeping your water clear and healthy.

Yes, summer care is crucial to keep your fish healthy:

• Ensure proper aeration as warmer water holds less oxygen.

• Monitor water temperature and shade the pond if necessary.

• Perform regular water changes to maintain water quality.

• Feed fish earlier in the day when temperatures are cooler.

Water quality is essential for fish health. Imbalances in pH, high ammonia, or nitrite levels can stress or harm fish. Proper filtration, regular water testing, and partial water changes help maintain ideal water conditions. Aim for a pH between 6.8 and 8.2 and keep ammonia and nitrite levels near zero.

The nitrogen cycle is a natural process where beneficial bacteria convert fish waste and organic debris into less harmful substances. Ammonia is first converted to nitrites and then to nitrates, which plants absorb as nutrients. This cycle is crucial for maintaining a healthy pond ecosystem. A properly functioning nitrogen cycle ensures low toxin levels and stable water conditions.

You can use a pond water test kit to measure key parameters like pH, ammonia, nitrites, and nitrates. Test weekly during warmer months and after significant changes like adding fish or plants. Bring a sample to our store, and we’ll help you analyze your water quality and recommend solutions.
