Bob and others should be along fairly soon to provide second opinions. CB1 - the water in Richmond Mill is tannin stained and I think fairly dark. I don't know if the concentration of stain has been tested, but someone may have Secchi disk readings?. Fish from dark brown tannin stained water typically have pretty dark hues due to the chromatophores adjusting to match the surroundings. Arron's fish lived in a black liner pond, thus their dark hues. I doubt the darkness of the colors are any different genetically between regular BG or CNBG.
