The golden part indicates that it is an asian arowana. There is only 2 strains of arowana native to Australia. Jardini's are considered extremely aggressive. Im not sure about Leichartdi's but they are more hostile then the the regular silvers.
the pic they posted is jardini, so i'd assume thats what they have.
i have to tell you though, the description they're using, "high grade golden 24K", don't apply to australian aro. those are description used for asian aro. they're just trying to hype up their sale with those words, which mean absolutely nothing in the case of australian aro.
That looks like the one i saw that was gold. To me this one looked more gold than some of hte jars I have seen but the people on here told me that they can actually change colors to their surrounding which I found out is true. Never the less, there is a guy who claims to have rtg jardinis, and it was on the same page that talks about how they change colors to their surrounding.
