This is most likely the fish you purchased as a Rainbow Dace. That is an old common name used for it. It is actually referred to now as a Red Shiner (Cyprinella lutrensis). It is in fact native to TX on down into Mexico, and is one of the most common minnows in the US. Also, its habitat stretches as far north as Minnesota. It has also been introduced in many other areas due to accidental release as a bait fish, and it has shown to be detrimental to native fishes in areas where it has been introduced. It should overwinter perfectly well in your pond, and the ones you bring inside should fair well if you decide to add a heater.
The coloration you find attractive now is probably the deep red coloration of the males' fins, tail, and especially the top of their heads, correct? That color will probably fade, but the fish will show a nice irridescent blue/lavender body, with faintly red/orange fins. However, all my native fish tend to stay very colorful in my planted tanks, and stay sexually active throughout the year. I personally think it is a combination of the security they feel in the heavily planted tanks, as well as the diet of frozen blood worms they receive.
One more interesting fact about this fish is that it was a very popular US Aquarium fish before the steady import of more exotic species. It was sold under the common name of African Fire Barb. Funny, since it's neither African nor a barb. Hope you enjoy your natives and decide to branch out to other native species.
