To protect your goldfish from predators, you can take the following steps:
* Cover the pond with a net or wire mesh.
* Build a fence around the pond.
* Remove any plants or other objects that could provide cover for predators.
* Keep the water level in the pond low.
* Feed the goldfish regularly so they are less likely to be eaten.
* Introduce some larger fish, such as Koi, to the pond. These fish can help to keep the predators away.
