My understanding is that black coppers are black lace based. I'm wondering if using super black would be better. I have read that by breeding super black to copper I will get super black with varying degrees of irid. Would using offspring with the heaviest irid crossed back to the copper parent make for a darker black with more iridescence-hopefully beginning to be replaced by copper?
On a side note, will breeding a marbled DS to a regular DS (the same color as some of the marbling on the first fish) keep the marble pattern tighter or is the full body coverage more dominant? I have been hearing to breed a marble to a solid to keep the nice big splashes of color instead breeding marble to marble and the patches getting smaller and smaller like on a grizzle. I will be testing that theory. I have a steel blue that I will breed to a steel blue/green/opaque marble. I have already bred her to another marble.
