Do you have to bring your fish inside for the winter?

Again ask, does Nature bring its fish inside in order to overwinter them?

Aquarium people usually think in terms of small bodies of water.
But a pond is a relatively large body of water and the rules apply differently
Nature you see, allows its fish to hibernate at the bottom of the pond.

You should allow your fish to hibernate over the winter too
Your fish will be healthy, happy, and very anxious to see you in the spring.
