One simlpe rule would cover all arowana species.
Recommended tank size for arowana should be a tank with a length 3 times the length of the arowana. The width/depth should be equal to thte length of the arowana. Not alot of emphasis is put on tank height but a 24" height really should be minimum for large aros.

Funny thing is this sticky doesn't even answer the majority of the questions you asked. Gets me wondering why it is even a sticky?
