I had a couple of other coexistence questions to ask as well. Can Rosy Red Minnows coexist with Koi or Goldfish in a pond without all being eaten?
Also is it possible to introduce Koi and/or Goldfish to a pond already containing Smallmouth Bass (I have heard Bass are highly predatory so i am wondering if they would eat them all?)

What's the difference between Koi and Goldfish besides the price?

Here is what Wikipedia says: Koi Differences from goldfish
Koi have prominent barbels on the lip that are not visible in goldfish. Goldfish were developed in China more than a thousand years ago by selectively breeding Prussian carp for color mutations. By the Song Dynasty (960 – 1279), yellow, orange, white, and red-and-white colorations had been developed. Goldfish (Carassius auratus) and Prussian carp (Carassius gibelio) are now considered different species. Goldfish were introduced to Japan in the 16th century and to Europe in the 17th century.[4] Koi, on the other hand, were developed from common carp in Japan in the 1820s. Koi are domesticated common carp (Cyprinus carpio) that are selected or culled for color; they are not a different species, and will revert to the original coloration within a few generations if allowed to breed freely.
In general, goldfish tend to be smaller than koi, and have a greater variety of body shapes and fin and tail configurations. Koi varieties tend to have a common body shape, but have a greater variety of coloration and color patterns. They also have prominent barbels on the lip. Some goldfish varieties, such as the common goldfish, comet goldfish, and shubunkin have body shapes and coloration that are similar to koi, and can be difficult to tell apart from koi when immature. Since goldfish and koi were developed from different species of carp, even though they can interbreed, their offspring are sterile.[11][12]

Thanks Ken. So Koi ARE Carp!
Since Koi and Goldfish are mostly plant and invertebrate eaters, the Rosy Reds will most likely survive.
When stocking fish in ponds with predators, it's best to stock them at a size that prevents them from being eaten.

Goldfish is a close relative to crucian carp (Carassius carassius). These crucian carps have possibility to survive in ponds where other fish might die because of lack of oxygen. Carps need much more oxygen than crucian carps.
