That is a nice fish. Bruce this link is the best pic of a male CNBG I have seen. I tried to post here but the site when copied will not let the pic be enlarged here. Take a look and tell me what you think. Colors , just as in regular BG, are more vivid during the spawn. Copper bars as well as color vary on male fish see second link below ,pics at the end of link. Todd if I find something worthwhile on your question I will post.
