Members of my lab went out to Estill Fork of the Paint Rock River in NE 'bama today looking for darters. We found tons of them, of course, and they were all in peak color. In particular, we found this one big, beautiful male rainbow darter. It's just a down and dirty hold in your hand photo, but the colors are amazing even so.

This is the site that I like to use
as an example of how drastic a water change these fish are used to.

I have seen these ultra-blue Rainbows before. I have heard, and I have a hard time believing, that the extra blue is caused primarily by the lower than normal amount of red pigment.

A lot of blues can be caused by optical effects of cellular structure rather than a pigment per se. Darter pigments are unlike any other fish pigments; Brady Porter at Duquesne University had a paper or two 10 years ago describing the unusual properties of these red/orange/yellow pigments that change color purely by concentration differences.
