I love Onyx, they were my first fish love back before they were called 'onyx'.
History as I remember it - When we got clowns from the wholesaler the PNG clowns usually had more black and we would find a few with black connecting all three bars pretty regularly. This was back in '99-02 I believe and anything with all three bars connected with back were 'onyx'. Then a shift happened (or they were getting labeled wrong IDK) and SI clowns were showing up with more black than the PNG clowns. Then came C-quest and Rods (c-quest) onxy that re-defined the term and standards. The clowns C-quest offspring had such rich colors and retained it in their offspring. I've known a few people who have amazing looking wild caught onyx and the offspring do not have the same dominate black coloring.
... but I think anyone who loves Onxy already knows this history
I have had MANY onyx over the years, WC PNG & SI, Rods, and now JCA c-quest line. I bet they are still burried online somewhere, I'll try to find some pics. I can honestly say out of all of them, the JCA c-quest I have now is the most stunning.
I'll snap some new pics of her this week. She is paired with a Picasso male, they do not host anything but have started hanging out around the frogspawn 24/7 just this weekend. I've only just received them in sept.
