Hawgdawg:
You are right, the original name Onyx was coined by Bill at C-Quest. He used to the term to describe the "early blacks" which were essentially fish that showed black at an early age. After successive generations of inbreeding/selective breeding for dark coloration, we have the C-Quest Onyx.
And I did state that the true Onyx are from C-Quest, and what I mean by that is the only line of Percula that I am aware of that will produce Onyx offspring are descendants of the C-Quest fish. My frustration comes from people who have a good looking pair of WC Perculas exhibiting the Onyx coloration, who will then sell their offspring as Onyx before they fully color up. In other words, I think in order to call them Onyx by lineage, there needs to be substantial proof to back up the claim, having dark parents is not enough. In the past few years I have seen some other breeders putting out some nice Black Percs that were not from the C-quest line, and I would say they are close to being able to be called Onyx.
And to answer your other question, I think my tastes have just changed over time, as much as I love Onyx, I just can't compare any fish to a beautiful WC looking fish, and no amount of black on a fish that has a messed up looking body will please me. Maybe I am just stuck up lol.
And, you are also right that it is a bit hypocritical of me to assert that the only true Onyx come from C-Quest while then stating that I am working on my own Onyx line, thanks for calling me out on that..

Again, what I mean to be saying is that, IMO, fish should not be marketed as Onyx unless they have a clear lineage showing that they are from dark parents that meet the Onyx criteria, and that their offspring will exhibit the same coloration. So to that extent, what I mean by "my onyx strain" is that I am working on developing a line of perculas that will consistently produce "Onyx" colored percs, but that are not inbred, which is why I have worked so hard on obtaining broodstock from many different locals. Again, the hope is to avoid the inbred deformities.
That being said, I have to give Kudos to Rod for the way he raises his fish. To the best of my understanding he raises his juvie Onyx in a more natural setting that produces higher quality Onyx than are typically other wise being produced.
Geez...that was really long winded, sorry for that!
