I was wondering where did they gold colour come from on the GJD's???
Gold Dempseys are Leucistic... Leucism is a condition characterized by reduced pigmentation.

Is it just a colour morph like the EBJD's???
Yup...

Is this Gold found out in the wild unlike the EBJD's???
It is "naturally occuring", meaning it is a genetic mutation that happened on it's own without human manipulation...
Once a Leucistic (Gold) individual was obtained by a hobbyist/breeder... They were logically paired off with other specimen to produce more Leucistic (Gold) fish. This is nothing more than "line breeding" or "selective breeding", not any kind of hybridization or genetic manipulation.

I am not 100% sure that the EBJD is a morph. I thought I have heard people say it actually occurs naturally. As far as the Gold, it may be the same thing.
Blue Dempseys, just like Leucistic Dempseys/fish/animals, just like albino fish/animals, just like tens upon thousands of naturally occuring thoroughly researched and documented traits... all follow Mendelian Genetics...
It is very well known that when we hybridize two species of fish... some offspring will look like the father species, some will look like the mother species, and there will be a very very wide variety of blends of the two...
It is very well known that this is NOT the case with Blue, nor Gold Dempseys.
It is very well known that Blue and Gold Dempseys both follow the exact pattern that Mendelian Genetics predicts, which is the absolute most common form of passing genetic traits within a species.

I still struggle with whether to call them gold or pink as they have both gold and pink in their bodies.
I would encourage you to refer to them as Leucistic to help promote accuracy in our termonology... "Common names" so often interfears with proper understandings...

Here is a picture of my largest male. He is about 8" TL.
He is one handsome devil...

I actually have one of those gold/ebjd's. I have had it for about a week now and it looks good. You can tell the difference in the EBJD and the Gold/EBJD it is a very nice looking fish. I cant wait for it to get bigger.
I'm thoroughly convinced that a single specimen cannot be both Blue & Gold... I elaborated on the science behind my belief in your thread about your fish...
Although absolutely no offense to you nor your fish... nor it's breeder. I just think it's going to blossom into a typcial Blue Dempsey... which is an awesome fish!
I don't mean to sound like a "know it all"... I've just put a lot of time/energy researching this topic over a number of years and wanted to share what I've learned...
