Jardini's are smaller arows. but also from what I've been told one of the nastiest ones. I'de pop your question over in the arrowana board. and 220gal seems to be the general conscensus for min arowana size tank. Not sure on availability ect but if he likes arrowana type fish might look at some of the gars instead or even a school of needlenose instead. I could be wrong so I'de check over in those sections for sure.
anyway so would that get on with a fire eel or what size is the smallest true gar?
I WANT A RED TAIL PAYARA google image it they're true monster fish at a foot long in captivity. so screw pirhana lovers this thing would pwn them to extinction !!!
