Creek chubs from the Eastern Piedmont region (e.g. Raleigh) can handle 85 F, but you obviously caught yours in a cool Mountain or Western Piedmont stream, based on presence of blacknose dace. For the BNDace's sake I wouldn't let it get above 75 F. That's great you have a place to keep it cool in mid-summer; i'm jealous. What stream/river basin are you in? NC-DWQ has a list of fishes by river basin here: Click "Freshwater Species by River Basin"
French Broad River Basin. Asheville, NC. As for the name of the actual stream I caught them from.... well I don't really think it has a name. It is literally only about 2 ft wide and at its deepest point MAYBE 2.5 ft deep and that's only 1 small hole the rest of the stream aside from several holes about a foot deep each varies from about 1/4 to 1/2 ft deep. Thanks so much to everyone for all the help so far.
