Permit me one qualifier.
When we stocked Richmond Mill Lake, I chose to stock some pure coppernose bluegill, some pure strains of natives and very likely some where intergrades of both strains.
While some of the photos above are definitely coppernose bluegill, some of them are likely crosses between natives and coppernose. So, don't assume all these fish are straight coppernose.
Those with brilliant copper-colored tails and the vivid copper band across their noses are definitely coppernose.
But, those with copperish-yellow dorsal fins may not be pure coppernose.
