Koi are delightful ornamental versions of the more common fish known as “carp.” Koi were bred for color by the Japanese for their private ponds or water gardens. But, as some of you may already know, these lovely creatures aren’t just for show. Their presence can help balance the entire pond’s ecosystem and even help to reduce pond maintenance.
Why, then, are so many pond owners anxious about keeping them in their ponds?
“People fear they won’t survive. It is true that koi can be tempting to cats, raccoons, herons, etc., but there is much that can be done to reduce such threats,” says Bill Renter from Deck and Patio.
Renter suggests adding koi castles and tunnels at the bottom of the pond to give fish a safe place to hide from many predators.
