Tropical Fish In Ohio?

Stayed local this weekend and hit Stadium Park for 2 hrs .  Sunfish, chubs, and little bluegill were very active in the crick, once the sun warmed up the slow pools.  Hard to believe such colorfull fish are in our cricks. Click on the photo to see the bright turquoise under its eyes.  Plus it's late November, the fish only know conditions, not what month it is.
