My camera at that time did not pick up blues worth a lick.You can almost make out the navy blue marks between the faint red marks in the picture as a gray. The dorsal fin doesn't look too bad, a good reference for the color on the sides. Females are highly variable in pattern, often looking like swamp darters.
I have little experience with darters, but thought I would post a photo I had. These guys do do well in aquariums, since not being a darter keeper, I did well with these. Rainbows are also really good choices. They usually have awesome color and adapt well. They can both get pretty "tame" and usually adapt to prepared foods and do pretty good on a diet like that.
