Greenside Darters?

Spent some more time in the Little Pigeon River yesterday and came across several darters that I'm not confident in the identification. I think I've narrowed it down to Greenside or Blueside Darters. I think that the individuals are broken up like this, parentheses indicate individuals: (1) (2) (3,4,5) (6,7).
I'm thinking that 1 through 5 have a face shape that fits better with Greenside. Individual (6,7) appears different, but it could also be because it was a lot younger (presumably, it was smaller). Using both my Peterson and the Fish of Tennessee, and I'm still having trouble getting some solid field marks other than ones that I would only be able to determine in hand.

Thanks for the help! I've learned so much on this forum and have been really excited to ID a lot of fish in the water, such a rewarding feeling!

By blueside are you referring to E. jessiae? If so, they are a very plain looking darter when not in color and unmistakable as a stigmaeum type darter when they are in color with tons of blue. I believe the first 5 photos are E. swannanoa and the last two are E. blennioides or whatever blennioides-like fish is in that area.

Agree with Dustin - the fish with rows of little rusty dots are E. swannanoa. See Fishes of Tennessee description.
I think the "greenside darter" variety in Pigeon River may now be considered E. gutselli, the Tuckasegee darter.
Not sure if gutselli and "true" blennioides overlap anywhere ... anybody know?

Nice Swannanoa pictures! I have been out snorkeling with them twice (once this afternoon) and have not managed a single half decent picture of one yet.

Trust me, it wasn't easy! I was afraid I wasn't going to get any. It took me a lot of patient stalking to get those!

Thanks for all the help guys, this forum has been a life saver for me. Just for my personal edification, what are some good field marks for these species? I see the W's on the side of the blennoides sp (which I assume to be E. gutselli), but what else should I look for (especially on the Swannanoa)?
