Rallys, and NE Cichlids....
First of all, I want to say that I have been nothing but impressed by NE Cichlids - stellar in my book.
As for this particular fish - Xanthic usually is attributed to an overall yellow fish (Like Bolty's golden jag.)
Then there are the "Gold Jags" which are copper with little or no markings.
Then there are yours, which are normal Jags with an increased amount of gold/yellow pigment. These are new, and have been floating around. I would suggest you come up with an all-new name for them yourself. Maybe "Gold Based Jag" or something like that?
(The above was not in any intended order.)
Hope this helps, Jude
