Does My Koi Pond Need a Fish Cave?

21 Jan 2021 Water Features

Predators are one of the most common problems that plague owners of koi ponds. If not protected properly, your koi can make an excellent snack for a massive variety of wildlife. There are many different ways to protect the fish in your garden pond with one of the most popular ways being to offer them a place to retreat from predators. A fish cave can be a great addition to any pond housing koi or any other fish that could be snatched up by raccoons, herons, eagles, owls, and cats. At Fontana Ponds & Water Features, we offer a wide variety of water feature design and construction services and we can help you decide if your koi pond needs a fish cave.

What is a Fish Cave?

Fish caves are simple nooks that fish can use to take shelter from predators and stay safe through the winter months. They are most commonly seen in koi ponds, as koi can be very expensive and hard to lose to predators. Many koi or goldfish ponds will feature multiple fish caves, depending on their size and the number of fish present. In most cases, fish caves are incorporated into the pond’s structure and are made to look like natural rock overhangs or outcroppings. They can also be made of plastic or concrete and can be installed in ponds after they have been around for a while. Although a fish cave will not protect a pond’s inhabitants from all predators, it can prevent those that attack from above from making a meal of your fish too easily.

Should My Pond Have a Fish Cave?

Determining whether or not a pond needs a fish cave depends on a couple of factors. Make sure that you consider the following questions when contemplating fish caves:

  • What kinds of predators are present in your area?
  • Do you have other protective measures in place for your pond?
  • How expensive are your fish, and how willing are you to lose them to wildlife?

If you have other protective measures in place, such as pond netting, wire grates, or a guard dog, it can still be worth installing fish caves to give your koi a shelter during winter. If you live in an area with birds of prey or other predators, having fish caves is one of the best ways to keep your fish in your pond. Although fish caves are not always strictly necessary, they can always be beneficial to the health and happiness of your fish.
