If the pond is of a decent size and amphibians could hide in the margins, fishes could work. Yes. Native species are much better. In very small ones just toads and newts are a satisfying choice. Add frogs if you don't mind noise.

If you have a place for a mini pond my advice is, don't built it.

Go for a small pond instead. Miniponds look nice on yoputube but are really unstable, and much more difficult to manage long term. They "boil" in a few hours at full sun. Freeze in winter and water must be added all the time. Is the same mistake as starting aquaria with a too small tank. Most people just will quit the hobby in a few weeks.
