Frequently Asked Questions

What types of koi does Connies Pond and Koi typically carry?
The shop carries a mix of koi varieties suited to backyard ponds, from common pond-grade fish to more decorative grades like Kohaku and Showa. Stock rotates regularly, so it's worth calling ahead if you're looking for a specific variety or size.
Can I get aquatic plants for my pond here as well?
Yes, their nursery background means they stock a selection of water plants that work well alongside koi. Water lilies, cattails, and other pond-compatible plants are typically available depending on the season.
How do I safely introduce new koi to my existing pond?
You should float the transport bag in your pond for 15 to 20 minutes to equalize the water temperature before releasing the fish. Staff can walk you through the full acclimation process when you pick up your koi.
Is Castro Valley a good climate for keeping koi outdoors year-round?
Yes, the Bay Area's mild weather means koi can generally stay in outdoor ponds throughout the year without a heater. You may need to adjust feeding in the cooler winter months when the fish's metabolism slows down.
What should I know about water quality before buying koi?
Koi are sensitive to ammonia, nitrite, and pH imbalances, so testing your water before adding new fish is a smart move. The shop can point you toward test kits and water treatments that help you maintain a stable environment.
How many koi can I keep in my pond?
A general rule is about 10 gallons of water per inch of fish, though larger ponds with good filtration can support more. Overstocking is one of the most common causes of water quality problems, so it's better to start conservative and add fish gradually.
