Ive owned a silver in the past and he picked on everyone since he was the larget fish in the tank and he grew reallyfast. Ive been thinking about getting a jardini arowana since they dont grow as large and he wont be the largest one so Im thinking he wont pick on eveyone but ive also had people tell me thire alot more aggressive. I would like to beable to mix him with my agtf, royal ck, and 2 stingrays and maybe adding a gar. what do you guys think? will he just pick on them intill thire dead or will he not pick on them because thier all larger?
