define cold. and if it's freezing, then no fresh water fish I know of can survive freezing. there are some salt water species that can survive being frozen in a block of ice because they have proteins that keep them from freezing because the water they live in is below the freezing point..
Freezing water meaning 30°f -60°f water

Can you be more specific? There are hundreds of species in North America and Eurasia that thrive in cold water conditions.
I want to keep some fish in my pond in arlington tx but it gets very cold here sometimes snows. I want fish that I don't need to take out for winter housing. I put a green house every year to keep it from getting freezing and to keep it warmer

Peacock bass and alligator gar can NOT survive freezing temperatures. They're tropical species, and are actually quite susceptible to freezing to death.

Some very well-known coldwater fish include lake trout, brook trout, Arctic char, grayling, arctic whitefish, burbot, sterlet, and lake smelt, but really any freshwater fish found more than 60% of the way up the northern hemisphere has to be cold tolerant... even if they will fail to thrive for long periods of time, most of them have the ability to survive temperatures nearing freezing.

If you're asking for freshwater aquarium species that are cold-tolerant, it's probably mainly cyprinids (carp, goldfish, dace, rosies, white clouds etc), although there are some specialist keepers out there (and on here) working with trout, sterlet, Siberian sturgeon, high-fin sharkminnow, and burbot.

Mosquitofish are also pretty cool, but most people find them drab and puny. I remember reading a story, it may have been on MFK, of someone who dumped a bunch of mosquitofish into a stock pond in their backyard during the summer and forgot about it until winter. Upon looking back, the mosquitofish were swimming around under the ice, picking at the hair algae.

Where you are in Texas and want fish for an outdoor pond, you will want something that can tolerate hot summer temps and you cooler winter temps. Perhaps some sunfish or catfish. What species are found local all to you?

sun fish look like the fish I catch all time when I go fishing . as well as blue gills. I don't really like those kind of fish in aquariums or ponds. I don't see them as pet fish rather food lol

+1. My pumpkinseed is quite the wet pet. Very personable, with little fear of me or water changes.
