There are different strains of pure black bars. Anyone can make claims to the unsuspecting public. There would be no way I would pay top dollar to someone that cant PROVE the pedigree. I too have what are called "Pure black bar", but that isn't saying much is it? I do know where the ones I have ancestors came from yet that proves nothing. I know they are true and throw trues colors without variance. Colors aren't the only trait that must be passed down.
Anyone that can't provide pictures on demand immediately, is suspect in my book. Even then, it's easy to google for a picture. I have seen too many "stories" to trust anyone. My skepticism is why I never spend big money on a fish, then too I have never seen a fish that I wanted so badly to throw caution to the wind and pull the trigger on it. Maybe one day that will change but until that day happens I guess I will still short-change some people undeservedly.
