Not at all. The exhibit is World Rivers and thus gives us views into random bodies of water from all over the world. I'm sorry but I can't really even tell you which river this guy belonged to though I think it was North American.
well it looks like a Catostomid to me (there's loads of species and I'm not overly familiar with North American fish so I won't go any further than that).
It's a fish in the Kentucky Licking River tank. The only fish in that exhibit that looks similar to this is a Shorthead Redhorse. It might be a Robust Redhorse though.
I kind of agree but Condor pmed me saying it was a Shorthead so I went with his conclusion. Perhaps he made a mistake as he pmed me part of Moebelle's statement and perhaps copied the wrong part.
