Don’t let predators take your fish on a life adventure

Fish Cave

Protect Koi From Predators Fish Cave

Installation of Fish Cave, Before Rocks Are Added

Our number one way to protect your koi fish from predators is to have a fish cave, or several put in your pond. This usually happens when the pond is installed. But fear not if you already have a pond, we can still create fish caves to save your beloved koi fish. Fish caves are hiding places that fish can go to escape from predators. They are usually a ‘tunnel’ of sorts, which is created to blend in with the surrounding rocks.


If there are many predators around your home, you may want to consider covering your pond with a net, especially at night, when many predators become active. Netting also works well in the fall, to catch any falling leaves or debris.


Koi Fish Predator Decoy

A heron decoy will help deter predators

Herons are territorial creatures, so if they see another heron in the area they are checking out, they will not intrude on this already dominated area. Herons also have natural rivals likes owls and snakes. Decoys can work very well to deter predators, just make sure to move the decoy around frequently so the predators don’t catch on to your game.

There are many ways to limit the impact predators may have on your pond. The first, more important measure to take is to make sure your pond is built correctly. A pond will typically have 2-3 shelves at varying depths, which is key because many predators will not venture into places where hunting is difficult and the fish can flee.
