If u want to do something diff and oddball.. try Lei arowana.. cousin of jardini..
A 240 gallon would be nice with almost any arowana.... as long as its 2ft width.. 24" is good for any giant size arowana really.. even silvers..
In terms of aggression.. u can mix silvers and blks together.. but not so much the latter jardini and lei are harder to mix.. should you choose to do more than one arow in your tank..
