Why are jardini arowanas so much more aggressive than other aros?

[Nabbig2]

I heard that jardini arowanas are aggressive; especially more than other aros. Why? Does it have to do with where they come from?

i guess it must be because they are an aussie native, and there are so many other aggresive aussie natives in the wild.....or maybe not

The same reason american cichlids are aggressive. It doesnt matter WHY they are aggressive. It just matters how you handle it.
