Identification of darter

I may have stumbled onto the answer to my identification problem through one of your members posts and wish I remembered where I saw it so that I could thank him or at least reference he or she here, for possible picture comparisons if nothing else. All help in identification is appreciated, though it will burst my dream of the previously unknown species thingy.
I was a little surprised at the darter find because it was on my property that has (2) 5 acre ponds that receive no water other than from local runnoff or ground water. No creeks even at flood levels. The ponds spill out into a wooded area , a creek of sorts that is all but dry, especially after last years drought that left it completely dry, and this is where it was found. That leaves three possibilities of its origins. 1. It made an almost impossible trip from the Pond River into my tail waters. 2. It came from one of my ponds possibly entering in with dumped minnows. 3. Carefully carried by local Blue Herons or another equally quallified critter. Still open to other possibilities here too.
Sorry for rambling but I feel this could be necessary information reguarding its location, range etc.
The closest comparison I have found on this site was an Emerald Darter. Though there were some slight differences.

I'm pretty sure its one of the E. stigmaeum complex, what's now called the bluegrass darter.
You'd be surprised what they'll swim up during "feast", and where they'll live during "famine". There are also a heckuva a lot of solution holes for them to come through. That whole segment there along the Parkway is divine. Is the geology there outwash from Glacial Lake Tight draining? I need to find a good KY geology book.
I've gotten a recent interest in the Pond, Tradewater and Red. I have a hypothesis this E. blennoides question is answered in Hopkinsville, KY. I can't say a whole lot more, I have to live with someone who WILL sue, but won't run any more samples. Please, someone pick up this tip and solve this question!

Besides, I thought E. stigmaeum had dorsal and lateral marking contiguous?

I just don't recall there being any of that "tinsel blue" on anything other than the stigmaeum clade. But again, that's where I should quit ID'ing things without lookin' in a book first

Before the recent find I had no idea how many darters and how specific their ranges can be. They are a very impressive species and not just for their beautiful colors. I definitely noticed an "attitude" in the darter, that made him stand out from other minnow types. Don't bother asking for an explaination I know it sounds funny but he acted like he was mad to have been caught.
It has taken me a bit of time looking up all of the suggestions that have been mentioned in your replies. When I Googled Images for Etheostoma gracile I saw a picture of a darter labeled "Backwater Darter" Etheostoma zonifer found on www.Outdoor alabama.com that looks like a match. Possible? I know my two days of internet research does not make me a biologist (actually a mining engineer) and I actually had trouble finding a good picture of the Slough Darter so my opinion means even less.
The first picture I took was actually a short movie because I had not checked my camera setting, I know everyone is surprised by that after seeing the great quality of my photos.
Thanks again this continues to very enlightening.
When I entered into gallery on this site my searches always came back empty. Any clues?

Farmertodd thanks for the link that is an excellent picture of the E. gracile. The base color does not look right but I understand the mating colors do change.
Is there any other pictures of a slough darter with the colors more like the Backwater?
I think everyone may be too focused on what species should be at this location, I agree with Newt on the Backwater Darter differences with the one I caught, on a closer look the Backwater has black or dark grey on both the first big fin on its back and on two of its belly fins. Sorry for getting too technical.
Thanks Skipjack, Sometimes I overlook the obvious. I am going back to try to catch another for better pictures and this time I will check the quality of the pictures before I release it.
The spots looked bluegreen to me hopefully better quality pictures will solve that question too.

Location is incredibly important in identifying fish. Species don't just jump around; drainage fidelity is very high, especially in small low-vagility species like darters. Introductions are always possible, but darters are uncommon in bait-bucket or deliberate introductions. Also remember that all fish species are variable; you can't make broad conclusions about a species' coloration based on a photo or two.
*EDIT* Oh, and thanks for the compliments on the tank! I had hoped to get some more of the renovation pics up, but the photographer is off to the ASB meeting this week (lucky stiff!), so it'll be a while longer.

Unfortunately, Newt is right that there is no current KY reference book; the distributional atlas by Brooks Burr and Mel Warren (1986) published by KY Nature Preserves Commission is occasionally available for around $30 and up, but it doesn't have any pictures. It's rumored that a new and improved version is in the works, but I've been hearing that for 8 yrs or so.

Newt and Ben thanks for the tolerance. Slough Darter it is!
A funny colored one. Just joking
