Top one as, 1/4ac says, is likely a mosquito fish or maybe one of the topminnows. Lower fish looks a lot like a small bluegill that has noticeably large eyes that strongly suggests it is stunted and not getting enough food for good growth.
My 2 cents.. Top looks like a Golden top minnow and the bottom is either a stunted BG as suggested above, or possibly a RES. I keep some of both in my aquarium over winter and it's obvious the RES have a bit larger eye than the BG do.. Absolutely no data to back that up, :-)) Just an observation on my part.
