OK I have posted something about this before (GOLD Jardini)

[PoopSmart]

Ok here is the deal. I posted something a while back abonut these red tailed gold jardinis, and everyone told me that the jars will just change colors according to substrate, which is true. That holds true for almost every fish. But I keep seeing these jardinis against the same backgrounds with different colors. Here is an example of what I think jardinis look like (silver with red spots sometimes darker or lighter depending on substrate) and what I think are actually different variations of jardinis.

Here are the examples of what I think are normal (or dominant allele) colored jardinis, body usually dark-light silver-gray, with red pearls (also I think another different phenotype that can be brought out with selective breeding, but I won't get into that), and a tail with sometimes the same body "pearling" coloring on it.

These are all pictures from juveniles to adults that I thought were good examples to illustrate the point.

Now here are the red tailed babies that turn into gold arowanas (RTG Jardinis if you will).

And an example of one of those red tailed babies at its adult stage

Now I got those from 2 different sources, one was a seller on aquabid and the other was the source I got them from first time I posted a similar thread, I found them on a guy's website who planned to captive breed them (if you search jardini it the first link to come up in google).


Now you can see the babies against the blue background in both different phenotypes and notice that with the same background they still have different colors, and more importantly, different patterns on the tail entirely.

This follows with the guy's RTG Jardinis that he captive bred. It looks almost like a sunburst tail, with bright red and yellow, and no spots or pearls on it. The colors are constant without interruption. The first picture is from a seller on aquabid and if you compare that to the baby on the bottom right (from the rtg jar breeding experiment website) their fin patterns are identical.

The adult that is pictured in his hand is one of the same babies just 10 months later. The tail darkened, but the body coloration is much different. I think these are probably recessive genotypes that produce this phenotype. Just like any other fish that is leucistic, xanthic, albino, etc. I dont see why it can't fall true for jardinis as well. There is a black silver and a regular silver. There are some silvers with a substantial more amount of red on them (kind of like the more pearly jardinis), and then there are silvers that have the red replaced with yellow on the fins. I think this is an actual different variation of the regular jardini.

That gold one has got to be a hybrid asianXaussie that color couldn't be achieved by selective breeding and it's tail is very different as well.....

But if it isn't a hybrid, then would you say that it actually does have a different phenotype or physical color difference than the regular jardini?

If its a hybrid, then maybe we can get asian aros into the states by buying these and selective breeding them enough untill all the asian aro traits are shown. Still would be marketed as a jardini right?


But furthermore, this is the real question, who in the right mind would try to hybrid a beautiful gold asian aro that would take a long time of selective breeding and strong genetics, to just take a chance and breed it with a drab looking jardini, and then spending enough more breeding time to breed back and forth between brother and sisters to try to get the result product? I think it would also show much more asian arowana physical characteristics other than just color, like body shape for example. It completely resembles a jardini's body shape. I mean I can even tell that there is more vieja or more texas in a flowerhorn by looking at the body shape (aside from the eye color, and pearls).
